On the evening of March 25th, at the B.TOP conference supported by the live broadcast of chain nodes, Wu Jihan, founder of Bitmain, stated that with the increase of the base of bitcoin users, its volatility decreased and the trend became more and more flat. This bull market may not fit well with halving. Since 2020, the global economic environment has become extreme, and the currency price has shown uncertainty. Miners must be fully prepared for this. Bitcoin does have the role of risk aversion in extreme situations. At present, there is only an economic crisis, not a world collapse. As the epidemic is brought under control and the global economy recovers, Bitcoin will also usher in spring.
