One by one, I don't know what to panic about, they are all old traders, the 30% pullback of AltCoin is expected, and it is a cliché to control Positions and pay attention to risks. I haven't opened an account for a day today, and short-term profit and loss should not affect long-term judgment, which is the psychological quality of a mature trader. I'll open the account now and look at the Position and you'll know, hey fuck, what about my Position?
