Talk about a current trading logic for altcoins in the short term, open the coin market capitalization leaderboard, scroll to the bottom, select altcoins with a market cap below 50 million and no observation tags, invest a small amount for a short-term trade, aim for a 20% profit and then exit, do not hold onto them.

Also, during the recent fluctuations of Bitcoin, do not buy certain altcoins that were performing strongly, because the next period is likely not their stronghold, but rather coins that have dropped significantly earlier will experience a wave of oversold rebounds.
