How to Buy Fractions of Bitcoin
This is a guide on how to buy fractions of Bitcoin. If you’re new to Bitcoin and cryptocurrency, you might look at the headline price of around $15,000 and think Bitcoin is too expensive. Is Bitcoin too expensive to afford? Actually no, because it is trivial to buy fractions of a Bitcoin. Each Bitcoin is divided into 100 million units, each called a ‘satoshi’. If you’re looking how to buy fractions of Bitcoin, the process is similar to buying a full Bitcoin. However, when you only want to buy smaller amounts of Bitcoin, there are some additional ways you can do so, which don’t scale up if you’re looking to invest tens of thousands of dollars. You don’t need to buy a full Bitcoin.

Bitcoin Conversion Guide

Before we proceed, here is a quick Bitcoin conversion guide to keep things straight.

Bitcoin is a cryptocurrency that can be divided up to 8 decimal places. That means you can easily buy fractions of a Bitcoin, even if you can only afford one cent! Just to get you familiar with the terminology, here are the conversions:

  • 1 mBTC (milli-Bitcoin) = 0.001 Bitcoin or 1/1000 of Bitcoin (a thousandth of a Bitcoin)
  • 1 uBTC (micro-Bitcoin) or 1 bit = 0.0000001 Bitcoin, or 0.001 mBTC (a millionth of a Bitcoin)
  • 1 satoshi = 0.000000001 Bitcoin or 0.01 uBTC (a satoshi is the smallest unit of Bitcoin)

Note: bits is becoming more and more popular method of denoting the number of Bitcoin, and you generally don’t have to deal with pesky decimal places. This has the added advantage of seeming similar to 2 decimal places that people are used to for money (e.g. dollars and cents). Others say we should just skip the intermediate bits and just move to satoshi.

Easy (Retail) Ways to Buy Fractions of a Bitcoin

If you’re new to Bitcoin or don’t know much about the technical aspects of it, you can still buy fractions of Bitcoin without too much hassle. However, be careful to only use trusted companies in the space, because there are a fair number of scams out there. Don’t chase a quick, slightly cheaper exchange rate if you’re not sure about the company and whether they are trustworthy.

Here are some options for you as a retail investor just getting into cryptocurrencies.


If you’re living in the United States or most of Europe, the easiest and most trusted way, especially for retail investors, is to buy Bitcoins at Coinbase. Coinbase stands out as a venture capital backed company that is geared towards the retail investors. This is a company that has raised $100 million in its last funding round and is valued at a cool $1.6 billion (Update: it is not valued at around $8 billion and is the largest Bitcoin company in the US). You can easily buy fractions of Bitcoin – e.g. $100 worth of Bitcoin or $500 worth of Bitcoin. If you use this link, you’ll get $10 of Bitcoin free when you purchase $100 worth of Bitcoin.

This is a full list of countries served by Coinbase: Austria, Belgium, Bulgaria, Canada, Croatia, Cyprus, Czech Republic, Denmark, Finland, France, Greece, Hungary, Ireland, Italy, Latvia, Liechtenstein, Malta, Monaco, Netherlands, Norway, Poland, Portugal, Romania, San Marino, Singapore, Slovakia, Slovenia, Spain, Sweden, Switzerland, United Kingdom, United States.

Update: Coinbase currently operates in over 100 countries, so chances are, this is the simplest way for most of you reading this. Here is a list of countries supported by Coinbase.

The signup process at Coinbase is somewhat similar to what a brokerage firm needs, only everything is online and the verification process can be more straightforward. They will ask for an identity document, and if your identity matches, you can start buying your Bitcoin almost instantaneously, i.e. within 10-15 minutes. However, sometimes the automated identity verification fails, which means you’ll need to wait to be manually approved. In those cases, you might need to wait a few days, depending on the traffic. You buy Bitcoin by linking your bank account or debit card. Coinbase also provides a handy online Bitcoin wallet, although it is advised not to hold too much money in any Bitcoin custodial wallet.

This is a company that has raised $100 million in its last funding round and is valued at a cool $1.6 billion. It is a trusted player in the space. You can buy Bitcoin by linking your bank account, and you can buy even small fractions of Bitcoins. When you initially login, the funds might take up to 3 days to appear in your account, after which you can purchase Bitcoins. You can also sell Bitcoins via Coinbase, and you can use it as a convenient online Bitcoin wallet. In addition, they offer multi-signature wallets too, which means Coinbase will no longer have any custody of Bitcoins.

Another good thing with Coinbase is that you can also buy fractions of Ether here, not just Bitcoin. Ether is the next most popular cryptocurrency after Bitcoin and has a vibrant developer community that not only advances Ethereum as a protocol but also builds applications using Ethereum protocol, thus providing value for the underlying Ether.

Square’s Cash App

If you use Square’s cash app to send money to friends in your local currency, you might be lucky and have the feature enabled that also lets you buy fractions of Bitcoin. However, please note that this isn’t universally available, and seems to be limited to the United States (and not to everyone). You can check out square’s cash app here. Note that it is being rolled out slowly so you may not be able to buy Bitcoin using the Cash App at all.


This method isn’t active anymore, as Circle removed support for retail Bitcoin buying, instead focusing on institutions. However, they appear to be getting back into the game.

In recent months, a formidable challenger to Coinbase has emerged: Circle. Circle doesn’t charge you any fees (although its prices to buy Bitcoin tend to be a little higher than Coinbase), and the best thing is, you can buy Bitcoin through credit cards. This is not possible at Coinbase. However, you have to pay the credit card processing fees in that case. You can avoid this fees by linking your bank account, just like with Coinbase. How to buy fractions of Bitcoin with Circle? Just enter the dollar amount, even as small as $10 and Circle will buy it for you. Note that Circle has currently stopped selling Bitcoin. However, Cash App from Square is an alternative.

Coinbase and Circle are the best ways, but if you’re looking for options, you can try Expresscoin or BitcoinInsanity. Both these places allow you to buy fractions of Bitcoin through credit card. BitcoinInsanity also allows you to buy through PayPal. However, the prices are higher.

For peer-to-peer trading, LocalBitcoins is a nice option. Use this if you’re outside the United States (or really want privacy with your Bitcoin purchase) and it’s hard to buy on online exchanges in your area.

Country Guide

Here are some other trusted places you can buy Bitcoins online in various countries:

US: Coinbase or Circle

UK: Coinbase, or check out this guide written by Coindesk. Be aware of the fees, which seems to be the norm for UK exchanges

Europe: Coinbase operates in these European countries, and should be the best option: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Finland, France, Greece, Hungary, Ireland, Italy, Latvia, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Spain, Sweden, Switzerland

India: Unocoin, Zebpay, or Coinsecure.

Philippines: or

Finally, if you just want a small fraction of a Bitcoin and willing to work online for them, there are a few options that you can explore (the payout is usually much lower than having a full-time job, so take that into consideration) in my Earn Bitcoin Guide.

Buy Gold with Bitcoin

Here’s a guide on how to buy gold with Bitcoin. You’d be surprised by how many different options you have in converting between Bitcoin and gold/silver, some of them physical gold coins or bars and some of them at an IOU level so you can speculate on the value of gold vs. Bitcoin.

Lots of people who are interested in Bitcoin are also interested in precious metals, especially the early adopters who were disproportionately libertarian in their philosophical and economic thought. Bitcoin, in fact, was and still is, often touted as ‘digital gold’ based on the scarcity of each. Gold has also been used in commerce for thousands of years and has a free market proven vibe to its properties. Both gold and Bitcoin attempt, in small ways, to bypass fiat currencies issued by governments, and both have become a store of value during turbulent economic times when there’s high inflation (think current day Russia, Venezuela, Argentina, etc.)

Here are some options for how to buy gold with Bitcoin, either the physical commodity or just getting the exposure to gold prices through a third-party. I’ll explain the options individually.

Amagi Metals: Amagi is another long-time Bitcoin supporting precious metals seller. They probably have the best pricing for your gold and silver coins if you pay with Bitcoin.

Agora Commodities: Agora is another Bitcoin supporting company that accepts Bitcoin for gold and silver coins and bars. The company is also a long-time supporter of Bitcoin and its community. You can buy your bullion in USD or Bitcoins.

Bitreserve: Bitreserve is a company founded by Halsey Minor (the founder of CNET) and aims to be a convenient currency exchange platform. It is definitely centralized like Coinbase, in that it holds your private keys. In return, you get the ability to seamlessly convert between Bitcoin, USD, GBP, Euro, CNY and yes, also Gold. If you want to get ‘BitXAU’ from Bitreserve, you just send Bitcoins to the ‘Gold’ card on your account, and that’s it. It will be worth a few ounces of gold, depending on how much you send. The gold is held in reserve by Bitreserve (and is therefore fully backed by the physical commodity, not ETFs and use GBI for this). The conversion is instantaneous, and you are effectively buying gold with Bitcoin when you send Bitcoins to your gold card. You can spend it as you would spend Bitcoin, by sending to any Bitcoin address. Do be aware though that there is a transfer fees of 2.4% in and out. The company is promising, has raised about $15 million already, and has a plan for the future. They are trying to add Oil to the mix, which would be quite interesting.

Bitreserve Gold Card

Ripple Singapore: This is a Ripple gateway for gold, silver and platinum. This is an IOU of course, and if you trust this Ripple gateway, you can buy and trade gold and silver throughout the world on the Ripple protocol. Ripple gets strong reactions from people in the Bitcoin community, but this is definitely one of the options. If you want to buy XRP (Ripple tokens), you can try Poloniex or Kraken.

BitGold from Bitshares: This is another interesting idea, using Bitshares. This isn’t an IOU (unlike Ripple) and the price of BitGold on the Bitshares network (one of the BitAssets, along with others like BitUSD, BitCNY etc.) is market determined, and is maintained close to the real price of gold by delegate feeds (101 delegates for the network). This is still a work-in-progress but as more people join the network, the tighter the spreads between BitGold and Gold price should be, and the liquidity is currently poor but hopefully will improve in time. You can buy BTS (Bitshares tokens) on an exchange like Bter.

Advertise Bitcoin Site

If you’re looking to advertise a Bitcoin site, you’ll learn soon enough how difficult it can be. One of the main reasons is that it is a small and niche community, and therefore harder to reach via traditional advertising platforms and methods like Google Adsense or Facebook ads. If you’re looking for the most bang for your buck in advertising dollars (or Bitcoins!) then it is best to promote directly to the people in the Bitcoin community instead of trying to advertise on venues that are open for all.

Even though hundreds of millions of dollars have flown into Bitcoin startups in the last few years, funded by venture capital firms, there are surprisingly few very good avenues to advertise a Bitcoin site to the community directly. Most of the best avenues are the ones that were built by the early community. Perhaps some startup will work on this problem soon enough, but for now, we have the following advertising methods.

Here are some of my top recommendations on where you can advertise a Bitcoin service or site that gets some eyeballs within the Bitcoin and cryptocurrency economy.

1. Anonymous ads: Anonymous ads is one of the most widespread advertising networks in the Bitcoin space. It is a pay-per-view (CPM) type of advertising, so you pay a flat rate to anonymous ads and it shows your ad to an audience. Although most of the sites here are in the Bitcoin and cryptocurrency niche, there are many that are not, so be sure to target your ad specifically to Bitcoin sites. They manually review all publisher sites and classify them accordingly. For instance, this blog is classified under Bitcoin, Blogs and News tag.

2. CoinURL: This is the largest pay per click advertising network in the Bitcoin space, and the rates are quite cheap, especially compared to something like Google Adsense. If you’re using Adsense to advertise your Bitcoin site, then I think it makes a lot of sense to try out CoinURL as well, since it is geared towards the community and the rates are lower too.

3. CoinAd: I would recommend using a paid-to-click type of service only for low-budget type projects, even though some of the biggest names in the industry, like, advertises here. If you have a good landing page with a fair conversion rate, this is a nice way to attract a lot of eyeballs in the community. This type of advertising is particularly good for Bitcoin gambling sites.

4. Reddit: I hope I don’t have to explain Reddit to you. If you can afford it, advertising on Reddit can be a very effective way to reach the wider Bitcoin community. You get the top link on the page, which is visited tens of thousands of times a day or more.

More ideas? Let me know in the comments.

Tourism Industry Bitcoin

Today there was interesting news that Expedia has started accepting Bitcoin for hotel bookings. This is an important milestone, as the travel industry is an important one for Bitcoin to crack. It is, I believe, the first step towards Bitcoin usage and adoption by travelers and tourists, a very big industry that would hugely benefit from using Bitcoin. In fact, international tourism is a $1.4 trillion dollar industry – let that sink in for a minute.

As more and more merchants start accepting Bitcoin, it is now time to look at the other side of the equation – consumers. What incentive do consumers have to pay with Bitcoin instead of credit cards? In the future, consumer adoption would be the key to Bitcoin’s success as a currency. Traveling/tourism is one of those industries where consumers have a clear incentive to use Bitcoin – they can end up saving as much as 10-15% on a trip as they don’t have to convert money back and forth into different currencies and pay the middleman a huge fees. Anyone who has used an airport currency exchange knows what a ripoff this can be.

Bitcoin Travel

With Expedia opening its doors to Bitcoin, it is only a matter of time before other travel/booking websites and agents do the same. They have a clear incentive to promote Bitcoin – lower credit card fees. The travelers have a clear incentive to use Bitcoin not only for booking but also for expenses incurred in a foreign country without inefficient currency conversion.

In addition, think of countries like Venezuela where there are strict capital controls. It’s much easier to use Bitcoin as a substitute for hard money instead of your dollars, which might always get you in trouble if you’re exchanging them at the unofficial market rate. Same with Argentina. Bitcoin needs to reach a critical mass of merchants, which seems to be happening at a rapid rate. After all, there is absolutely no downside to any business accepting Bitcoin through payment processors like Coinbase or BitPay that convert the Bitcoin to local currency immediately.

When it comes to currency, I think the travel industry would be the stepping stone for Bitcoin’s success.

Feb 072014

The concept of Bitcoins has taken the world by storm, ever since its inception in 2008. Since it is considered to be one of the best sources of legitimate cryptocurrencies, a lot of people and companies alike are beginning to see the importance of using Bitcoins to do their financial bidding.

There are 3 major ways to transact in Bitcoins: mining, buying and trading. Now the pertinent question here is, “Is it better to mine, trade or buy Bitcoins?”

Let’s check each in detail and see which comes out to be the best of the lot.

Bitcoin Mining

Bitcoin Mining is the process through which Bitcoins are created and circulated into the Bitcoin system, as well as added to the blockchain, which is a record of all Bitcoin transactions through time. The mining process is rather complicated and needs an expensive and well planned strategy in order to make a profit. A lot of Bitcoin mining today is run via large data centers and not in people’s homes. There are some reasons which make mining all the more difficult and cumbersome to carry out. These can be categorized in the following manner:

  • Security of the networkThe mining process is decentralized. Anyone who possesses a good strong hardware system and a stable Internet connection can carry out the mining process. However, if an individual or an organization possesses more than half the control of the Bitcoin network’s mining capacity, then there are chances of the network being unduly influenced. This is where the breach of security happens, making the procedure insecure.
  • Transaction fee: Given the high transaction fee involved with the mining of Bitcoins, there is a diminishing interest within the minds of people. The declining rewards and the increase in the transaction fee, creates a negative ripple in the market, causing a substantial shift in the minds of the people.
  • Mining complexities: The level of mining difficulty gets adjusted every 2 weeks. As the complexity level fluctuates, so does the mining possibilities. If more computational power is employed, chances are that the mining procedures would also become more difficult, causing miners to avoid mining in the long run.

Buying Bitcoins

Before you actually think of buying Bitcoins, you should think through all the options and then arrive at a well informed decision. Today, there are many great sources throughout the world to buy Bitcoins, like Coinbase. Here are some reasons why you may want to stay away from buying Bitcoins:

  • Losses: With some of the other financial instruments available in the markets these days, there are safety procedures in place, which help you in case of any imminent disaster. However, with Bitcoins, there is no such safety net, which can bail you out in case your Bitcoins get lost or stolen. While you can store the Bitcoins in a wallet on your hardware or keep them with a third party, there is still no surety, that your investment will remain safe eventually.
  • Regulation: If regulatory advice is to be believed, one would realize that there are higher chances of being swindled out of your hard earned investment as would be the case otherwise. The lack of strong regulation on this volatile virtual currency can leave you bare, making it hard to invest in Bitcoins.
  • Trading Bitcoins: Like any financial instrument, even Bitcoin trading is somewhat reliable and profitable. The trading procedures use the rise and fall in the price of the virtual currency, to actually estimate the profit/loss in the exchange. Sharp skills to trade Bitcoin’s value fluctuations is what makes a successful Bitcoins trader; a trader by profession is required to offer exchange services to other Bitcoin traders, so that he/she can himself make a net profit on other investors’ transactions. A trader can make buying offers, when the price is low, and later on sell the currency at a higher price, allowing him to make a profit. However, in order to be a successful trader, one has to possess impeccable knowledge on how the system works.


These are the three ways to transact in the Bitcoin economy, and in the process, gain some Bitcoin. Simply buying Bitcoin is the simplest of all but has a limited profit potential. Trading Bitcoin is risky but can have the highest return among the three methods.

best bitcoin sites
Here are the best Bitcoin sites that will allow you to earn Bitcoin online. If you’re looking to make some Bitcoin performing small tasks online, then this is the perfect list for you. I update this list regularly, with only the best sites out there.

The Bitcoin economy is a fast changing one, and there are several sites that come up that allow you to make some Bitcoin online. You should remember that this can also be a time-trap and you can get sucked into it for long hours without having much to show for it. This is why you need to filter these down.

Also, I am not covering the obvious ideas – yes, you can just get a job, get paid in USD and convert those to Bitcoin but that’s not the point of this article. Remember that small amounts of Bitcoin can add up, as the following Wired article shows.

For a more comprehensive list, see the how to earn Bitcoin online page.

Updated: 08/15/2018

A special mention to online wallets like Circle and Coinbase that make it really easy to buy and sell Bitcoin to a lay-person. Of course, if you have substantial amount of Bitcoin (say over 2 BTC), get a LedgerTrezor or KeepKey – hardware wallets that stores your Bitcoin offline in a secure enclave.

#1 Coinbase: Coinbase has been the staple of the Bitcoin and crypto world for quite some time now. Valued at several billion dollars, they are a lot of things, including an online wallet and an exchange. They are looking to expand into everything from institutional custody to blockchain identity. If you’re new to Coinbase, you can go through this link and get $10 of Bitcoin for free. Coinbase is fast expanding to other geographies and also other cryptocurrencies, such as Ether, Litecoin, and BCash.

#2 Binance: Binance has become the #1 crypto trading website in the world. It is estimated that last year Binance made more money than the London Stock Exchange Group! That’s saying something (although that was at the peak of the crypto mania of 2017). Still, if you’re looking to invest or trade in Bitcoin, Ether, and other cryptocurrencies, you should definitely make Binance your first destination. It has liberal limits of 2BTC withdrawal without KYC, making it one of the best bitcoin sites out there in terms of ability to trade Bitcoin with altcoins without giving documents to shady exchanges.

#3 21 Tasks21 is the Bitcoin startup with the largest funding so far. It is purely a Bitcoin company so far, not a ‘blockchain’ startup. This makes it one of the best Bitcoin sites out there, and certainly one of the most promising ones. It uses Bitcoin to try and do things that weren’t feasible in the old economy. Even if these things don’t add up to much today, they can be game changers tomorrow. There are a few ways to earn money via 21. If you’re someone well known, you can set a price for people to reach out to you, and when you reply to their message, you get your set price. This reduces spam, and you get paid for the effort (or donate your earnings to charity). There is also 21 tasks that you can do on your phone or some of them on your desktop. The earnings are decent – significantly higher than the PTC type earnings. In the future, it will perhaps compete with the likes of Amazon’s Mechanical Turk. 21 got acquired by Coinbase recently.

#4 Anonymous Ads: This is my favorite Bitcoin ad network and I like this more than others like CoinURL, BitMedia, Operation Fabulous, BitAds. Unlike the others mentioned which are pay-per-click, anonymous ads is a pay-per-impression system and the payment really depends on a number of factors. The stats are amazing and everything is open for you to see. I use this on my site as well and I am happy so far. If you own a website or blog, this is a very passive way to make Bitcoin. They are perhaps the longest running ad-network for the Bitcoin community, and the owner has been a very regular member of Bitcointalk forums since the very beginning.

#5 Coinality: Coinality is hands down the best jobs aggregator in the Bitcoin space. If you’re interested in the Bitcoin and cryptocurrency space at all, definitely keep an eye out on Coinality. It allows special listings on its own site, but also sources jobs from across the web from Upwork and Elance to mainstream job sites like Indeed. They also have jobs of all types, from full-time developers to freelance writers. You will find small gigs, like logo design to full-time software developer positions on companies like Coinbase.

#6 BitcoinGet: The popular site that was mentioned in the Wired article on how homeless guys were able to use BitcoinGet as a form of ‘digital hustling’. There are two popular ways to earn some Bitcoin here – Micro-tasks from CrowdFlower and watching Virool videos. The micro-tasks pay anywhere from 30-600uBTC depending on the task, and there are several tasks that you can do in a single day. The virool videos currently pay 40uBTC for 30 seconds of video. Availability depends on the location (e.g. in the US, on an average, there are 10-12 videos per day, so you can earn close to 400-500 uBTC just through the videos and then some more from the micro-tasks). Payments are automatic, and usually processed pretty promptly within a day or two. The site has also added Surveys to the list of ways to earn Bitcoin.

#7 Paid to Click (PTC) Sites Paying in Bitcoin: BitsForClicks (previously Coin Ad): This has remarkably become the most popular and sustained Paid to Click Bitcoin site. There are several reasons – it has a very good inventory of ads and it always has a steady supply of ads. Being one of the oldest, still surviving Bitcoin PTC sites also helps. The low minimum payout makes it a low risk investment in terms of time for many bidders. They have done pretty well so far – it is a relatively old site, and is growing in popularity with the advertisers. If you have to pick just one Bitcoin PTC site, this should be the one. As a bonus, if you like this niche, also check out BTCClicks.

 Bitter: Bitter started off as the best Bitcoin PTC (paid to click) out there, but the experience has deteriorated over time. Still, if you’re a PTC enthusiast, it is worth checking out. On the plus side, they don’t use silly ‘bux scripts’ that all other PTC sites seem to be using, but instead do it from scratch, in HTML5, giving Bitter a much nicer user experience. There are also no silly recaptchas to complete – the verification is simpler. This is especially important if you’re accessing this via TOR where recaptcha is a pain.


#8 iFaucet: This is the best Bitcoin faucet rotator, which can give you a fairly significant amount of satoshis for faucets if you follow all the sites. It manages the entire process for you, and is a fairly comprehensive and updated list of all the Bitcoin faucets out there. In addition, it has very good search filters, so if you hate one type of captcha, you can remove it from the list. You can also blacklist sites that you don’t like. Finally, iFaucet blocks annoying popups and other undesirable page elements, so it’s a smoother browsing experience.

#9 Predictious: Predictious is a Bitcoin prediction market, and you could earn money by suggesting new bets/statements and also predicting the right outcomes of future events. However, be on the lookout for some new decentralized prediction markets that might eat centralized prediction markets’ lunch. Most notably, Augur, built on Ethereum but allows Bitcoin bets directly, is building a fully decentralized prediction marketplace that will easily undercut Predictious in terms of trust, security, and fees. Augur has raised several millions of dollars overall.

Ads4BTC: This is a very nice Bitcoin PTC site, quite similar to Neobux in its look and feel, but with Bitcoin payments of course. They generally have a good ad inventory, which is essential for a long-term sustainable PTC. The ads are sorted based on the time, and the payment per ad is upfront as well. The site has a lower payout available through a microwallet, or regular Bitcoin payments as well but at a higher minimum payout.

ABitBack: This is another popular site to make some free Bitcoin online. The most popular service here is Radio Loyalty that pays you 1 point (30uBTC) every few minutes for just listening to the radio. Supersonic Ads and Virool Videos are also popular, although Virool videos pay less than at BitcoinGet. There is also support for Litecoin (also see how to earn Litecoin).

Coin Chat: This is one very great way to make some Bitcoin just chatting with your fellow Bitcoin enthusiasts and learning about everything from Bitcoin to politics to programming. You can just have fun and chill in any of the chatrooms and you’ll randomly get some Bitcoins. It isn’t very much, and you should do this only if you enjoy getting to know other people on the internet in the Bitcoin community, but say an hour of serious discussion can yield about 1mBTC.

Bit Visitor: I had to include this because it is one of the oldest, still working paid-to-click ad viewing site that pays quite well. You can reach payout almost every day because the minimum is just 100uBTC. The site has had problems on and off, but overall it has a good name in the community and attracts lots of eyeballs and businesses.

Daily Bitcoins: This is the only faucet I’ll mention just because it is that good. It pays 10uBTC every hour. If you have the time and you spend a lot of your time online, you might as well use it every hour. Note that there are also several bonus payouts, with as high as 1000uBTC payments (rare) but several 50uBTC payouts. You’ll find these under Prizes tab on the top. You’ll also get several vouchers for PeerBet and coupons for advertising on that site as bonus.

Rewards Live: Rewards Live is quickly becoming one of my favorite site for micro-payments in Bitcoin, even though I was initially skeptical of its success. They are doing pretty well and look quite sustainable. Rewards Live perhaps has the highest number of different ways to earn Bitcoin online, which is why I would classify them in the list of best Bitcoin sites. Here is just a snapshot: Matomy, Sponsor Pay, Radium One, Super Rewards, WallAds, RevU, Payment Wall and more being added. Even the payout options are plenty – you can withdraw via Bitcoin, Litecoin and Namecoin, but if you don’t want to go via the cryptocurrency route, there are scores of gift cards where you can withdraw as well (of course, I would suggest Bitcoin/Litecoin/Namecoin!) The site is adding luck-based giveaways to the various ways to earn money, which is an added bonus.

These are the best Bitcoin sites that I know of where you can earn some Bitcoin online. I have a more comprehensive free Bitcoin section that might interest you as well. What do you think of these services? Let me know.

Bitcoin Scams

Beware the Bitcoin scams – they are here, live and well, all ready to rob you out of your Bitcoin. If anything, the frictionless Bitcoin transactions make it an ideal vehicle for scammers. If something appears fishy, just because it has a fancy Bitcoin name in front of it doesn’t make it legitimate. You need to understand the very basic ideas of risk and return and anyone who ‘guarantees’ you a return above that of the treasury bonds is simply lying (the libertarians in the audience will note that the government is lying when with the treasury bonds too, but that’s a discussion for another day).

Even though many people who consider themselves tech-savvy promise they’ll never fall for these scams, there is plenty of evidence to the contrary, especially with social-engineering attacks (e.g. see this for a few examples) and other resources these scammers employ. With Bitcoin, things become even more tricky since there is no ‘chargeback’ so to speak and it’s virtually impossible to identify the real identity of a scammer.

Bitcoin Ponzi Schemes

The most common form of Bitcoin scams take the shape of a simple ponzi scheme. If you don’t already know, that’s a scam where new money is used to repay old commitments instead of a real investments being the source of wealth-creation. This is obviously unsustainable and has to fail at some point of time (the Madoff case was a $50 billion ponzi scheme).

The best known Bitcoin scam to date also happens to be a ponzi scheme by a Texas man who ended up collecting more than 700,000 Bitcoin! What was he promising? A 7% weekly return. And people genuinely thought this was legitimate. What a tragedy!

The New Bitcoin Ponzi Scheme

The problem with Bitcoin ponzi schemes is that there is no oversight. It isn’t terribly hard to slap together a website that accepts Bitcoins (it only needs to accept Bitcoin, not pay back!) that promises riches. I was surprised that BitVisitor, a generally respected advertising network in the Bitcoin community, ran this Bitcoin ponzi scheme ad on its network. I hope people didn’t fall for it.

Site: GrowCoins (growcoins dot com. I refuse to link out to this site from my blog)

About the company – from the company’s homepage: will work for ever, With our company your dreams come true. is engaged in the investment increase your money. That is, if you urgently need a large sum of money, or make money online, our site is for you. Our company has many experts who are constantly monitoring the rise and fall of shares in other companies and exchange rates.

Here are the advertised rates:

Bitcoin Scam Ponzi GrowCoins

Yes, GrowCoins is a ponzi. What a shocker. Look at their ‘diamond’ package above. They are promising to pay out 10.5% daily forever. If you are still considering, this is how 10.5% daily interest rate is going to look:
Day-1: $100
Day-30: $2332
Day-100: $3.63 million
Day-365: $4.39 X 10^18, which is 4.39 trillion trillion dollars.


The early adopters in the Bitcoin community are fairly smart, and one would expect they shouldn’t fall for such outright scams. Then again, the biggest ponzi scheme in Bitcoin’s history did manage to get more than 700,000 Bitcoins which is a lot. These are best weeded out of the economy, but with something as incredible as Bitcoin, there are bound to be these kinds of Bitcoin scams I guess. Stay away.

Where do you buy Bitcoins in the US? There are several different ways to do it, depending on an interplay of privacy and cost. Right now, in the Bitcoin market, there exist considerable price differences with different sources. You need to be intelligent about buying Bitcoins in the US because you can usually get a much cheaper rate than at MtGox for instance. Here are some best ways to buy Bitcoins in the US that I found –

1. Coinbase: Extremely convenient, not anonymous, best price

If you’re not looking for anonymity, Coinbase will give you the best price, period. I found the price here to be lower than even the in-person meetups where people had made a market in BTC/USD. It is also usually about 10% cheaper than MtGox price, so there is really no reason to buy on MtGox ever (even including the 1% fees charged by Coinbase). The only reason you might want to move away from Coinbase is if you want to buy Bitcoins anonymously.

I have the highest confidence in Coinbase also because it is backed by some of the biggest Venture Capital firms, so I know they are not pulling a scam.

Also, if you complete all the identity verification processes, you can buy up to 50 BTC instantaneously each day. That means you don’t even have to wait for confirmations to spend your Bitcoins that you bought. I think it’s a great service.

2. Bitcoin Brokers: Completely anonymous, Premium Pricing

This is a completely anonymous service. You deposit cash into the bank account of the seller of the Bitcoin and you’ll get your Bitcoin when the seller confirms or within 48 hours of this. The price is based on the MtGox price plus a premium, usually 2%-3% so it is definitely much more expensive than Coinbase. However, you don’t need to disclose any identities in this case. The service itself acts as an escrow and you pay a 2% fees.

This is a good method to buy Bitcoins in the US if you’re located far away from a city or a place where it is hard to meet people in person and you still want to maintain your anonymity. Or for whatever reason, you don’t want to meet sellers face to face to confirm transactions.

3. LocalBitcoins: Convenient, semi-anonymous, average pricing

Localbitcoins is a site that aims to bring buyers and sellers together. The price is usually higher than what Coinbase offers, but you have relative anonymity here because you don’t really need to reveal your identity when buying Bitcoins. That being said, there’s always an element of risk when you’re dealing with this locally because someone might try to scam you. Keep your guard up and always meet at a public place and wait for at least one confirmation of the transaction before you part with your cash.

If you live in a place like New York, you can buy Bitcoins in New York from a very enthusiastic little group of people who meet at Union Square every Monday from 5pm onwards, called now the Satoshi Square meetup. There are similar meetups in a number of larger cities all over the country. This can be a good place to buy some Bitcoin and network with the community.

These are the three easy ways to buy Bitcoins in the US. Have you tried any of these? Do you know of other ways? Let me know.
