Unlike the dollar and the euro, bitcoin is not issued by central banks. Instead it is “mined” or created in computer “farms” like this one.
It uses computers souped up with six graphics cards tasked with the heavy lifting of thousands of thousands of calculations needed to solve complex algorithms to process bitcoin transactions and be rewarded with bitcoins in exchange. “It’s possible for everyone to do it at home.
There is no one stopping you (and) there are no technical limitations,” said Philip Salter, head of operations at Genesis Mining, told AFP. Last year saw a meteoric rise of hundreds of virtual currencies led by bitcoin, which was fetching almost $20,000 per unit in December as both amateur and professional miners jumped onto the bandwagon.
