you need to take into account certain risks. Among them is the fact that the price of bitcoins and other crypto-currencies does not have real assets, therefore, it is often subject to strong fluctuations. If today you can earn several thousand dollars on investments in BTC, tomorrow there are risks to lose ten times more. In reality, not one digital currency, and bitcoin is an exception, has not yet been recognized as a legal tender. There are no legal bases guaranteeing the security of such operations. Any risks associated with BTC trading are entirely on the investor.
