Bitcoin was released in 2009 by someone going by the pseudonym of Satoshi Nakamoto, who wanted a virtual currency that was unrestrained by regulation, he subsequently left the project. Cryptocurrency is therefore an attempt to replace money transactions with a digital medium of exchange using peer-to-peer networking. The first decentralized cryptocurrency, and still the most successful, is Bitcoin.

The idea is that you use cryptography to control the creation and transfer of money, rather than relying on central authorities. There have even been crowdfunded cryptocurrencies such as Lisk. Many other cryptocurrencies have just died because of lack of interest, and the simple fact that no one used them. Non-Bitcoin cryptocurrencies are collectively known as altcoins and they are more or less based on the same idea of a decentralized digital medium for exchange. Since Bitcoin is open source, anyone can develop their own cryptocurrency using the same technology.

Bitcoins derive their value partly through their scarcity, which is defined by a cryptographic lottery. Coins are awarded to whichever miner happens to compute a number below a certain threshold. Originally, Bitcoin mining was handled by standard PCs with powerful graphics cards, but as the hash difficulty has increased, the preferred method to mine Bitcoins is to employ a Bitcoin ASIC, a chip that has been designed specifically for this task. GPU processing power, miners have once again been turning to graphics cards for mining. This lottery favors those with the biggest and fastest machines, and currently there are about 17 million Bitcoins in circulation. 21 million because of the way the system was designed. As the Bitcoin network gets bigger, the hash gets more complex, and miners get fewer Bitcoins for their trouble, hence they always need better hardware and higher Bitcoin prices to make it worthwhile.

As a currency, Bitcoin is still a niche market. However, multiple established retailers accept it as payment including Overstock, Expedia, Newegg and the Dish Network. Since Bitcoins can be spent on the internet without the use of a bank account, they offer a convenient system for anonymous purchases, which also makes it possible to launder money and buy illegal products. Credit card fees, also known as swipe fees, can often exceed the value of the purchase, making this costly for retailers. However, Bitcoins increased transaction fees have proved to be a barrier preventing it making inroads into the world of micropayments. Another problem with Bitcoin is the volatility of its value which exceeds the volatility of other currencies and gold, resulting in huge fluctuations in comparison to the US dollar.
