2015 Bitcoin price

While a single Bitcoin costs tens of thousands of dollars , the cryptocurrency (trading symbol BTC or XBT) can be bought and sold for fractional shares, so your initial investment could be as low as, say, $25.

In 2011, the Electronic Frontier Foundation (EFF) accepted BTC for donations for a few months, but quickly backtracked due to a lack of a legal framework for virtual currencies. In February of 2011 , BTC reached $1.00, achieving parity with the U.S. dollar for the first time.

You cannot mine just 1 Bitcoin, instead crypto miners will mine one block, with the reward set at 6.25 BTC per block . Each Bitcoin block takes 10 minutes to mine. This means that in theory, it will take just 10 minutes to mine 1 BTC (as part of the 6.25 BTC reward).
