$PI If you don't understand this project, just hold on to the coins you've mined well, don't always think that you can make money by simply selling high and buying low, the money in the market isn't as easy to earn as you imagine, others aren't fools. If you don't even know where to look at the data, and don't take data as the core, always guessing and analyzing blindly, if you gamble today on tomorrow, and lose, don't complain. If you can't understand why others can win while you keep losing, then you deserve to be cut.
