$BTC Don't say that if the mining machine costs 50,000 to 60,000, Bitcoin will not fall. According to the halving every four years, how much will it cost next time? A large number of new coins are launched in the primary market every day, and the funds are scattered. Bitcoin soared by 10,000 points, and the copycat rose a little, and fell by a thousand points, which was even faster than the rise. The current model of the currency circle is to speculate on the heat. Don't think about how many times it will increase. If you buy ten coins, it is estimated that they will fall dozens of times and then increase several times. Most people play copycats. If they make a profit of 30%, they can basically run away. Don't say that the follow-up is the bull market of copycats. From 15,000 to 73,000, there are a few copycats that will increase several times. The later you enter the market, the worse it will fall. The currency circle is no longer a spot that can make a profit. Who said that the rise is unlimited and the fall is limited? The rise requires a lot of funds, all real money, and the fall only needs to be cashed out. It is difficult to rise by 5%, but it is very fast to fall by 10%.
