When they first appeared on the market, bitcoins were valued at the modest amount of $1. After this soared to a value of $1,000 in November 2013, it has since settled at $630 a piece. The proliferation of bitcoin users goes hand in hand with the emergence of operators providing bitcoin-related services – enabling, for instance, the exchange of bitcoins for conventional official currencies. Since the inception of bitcoin, the European Banking Authority (EBA) and the European Securities and Markets Authority have been charged with its supervision.
