Some time ago, a developer named Satoshi Nakamoto decided to create a decentralized, completely digital currency. As a result of his hard work, now there is a significant group of traders that have been successfully trading this currency right under our noses for the past few years. The currency and open source software used for trading are both called Bitcoin.
it's interesting seeing rates written from a Forex trader's perspective:
Initially, the Bitcoin was priced at 1,309.03 BTC per dollar, and now, four years later, the price is about 0.070771408 BTC per dollar
