How to put it? If playing spot trading can make money, who will play contract trading? Last year when the meme market was good, it actually snatched up many contract users. But in the recent market trend, if you don't short, there really isn't any way to make a profit. Playing spot, contract, and meme in the cryptocurrency circle is high-risk. The contract itself is not wrong, what is wrong is human nature. Actually, I have found that the risk of meme contracts is still higher than that of contracts, but high risk often means high returns.
