In Japan, you can have a good dinner in a restaurant, paying the bill with cryptocurrency.

However, not everyone is in a hurry to spend their savings in this way, which are stored in the form of a digital currency. Most owners of bitcoins who buy coins from miners, deep down hope that the rate will rise unexpectedly and there will be an opportunity to sell crypto currency profitably. This is one way how to earn with bitcoins. Thus, many of those who bought the digital currency as soon as it began to gain popularity, were able to make a fortune.
