Fundamentally, cryptocurrencies are challenged by global Central Bank restrictions as well as the potential prospect of identifying them as unlawful. The driver of serious growth could be the legalization of mining and investing in cryptocurrencies in Russia - after a complete ban on mining in China, farms moved to the Russian Federation and Kazakhstan, causing a lot of talk about the advisability of further work with cryptocurrencies. A particularly good sign for bitcoin will be the resignation of the head of the Central Bank of the Russian Federation, Elvira Nabiullina, who categorically disagreed with the Ministry of Finance and demanded a complete ban on cryptocurrencies in Russia. Given the tightening of the trading range, Bitcoin might rise or fall sharply in the near future. After breaking through 44,000, a sharp increase may begin, support is the mark of $37,000.
