Anyway, you can't play better than the exchange; only the big coin exchange can't control the market.

I was wrong. I originally thought that Bitcoin would stabilize above 110,000, and that altcoins would have a nice rebound. So a few days ago, I went long on a batch of altcoins, but ended up getting stuck. If Bitcoin pulls back, there is a risk of liquidation. What I thought would be a rebound turned out to be a trap. My understanding was insufficient!
