I saw it too late; I was playing cards. After thinking for a minute, the volatility subsided, and I missed out. The market is too dry right now. You have to monitor the market constantly and make judgments and take actions within minutes. You can't survive without real trading skills. The scariest thing is that US stocks are still at high levels. If US stocks experience another big correction, will cryptocurrencies even survive? Good luck, hold on until the next cycle.
