Absolute phenomenon. This is one of the most famous digital currency names. Bitcoin, which has had a turbulent history full of fluctuations, is gaining more and more fans. It can be paid even in many eshops and other places. From my point of view, bitcoin is not yet at the peak of his glory. Digital currency, whose great advantage is its anonymity, opens the way for new ideas and opportunities for business. In spite of high volatility, bitcoins may surprise us in the future.
