Don't you see that if alts still increase even higher than before? if you are looking for the best strategy and try to sell some of your coins to the stable coin to anticipate the dump and you can keep the rest in your wallet and prepare it when bearish signal will be coming soon.

The end of altcoin season can't be determined yet and you must always watch the market to see whether there will be a bearish signal or not but i do believe if we will not see the bearish trend in a short time.
The fundamental of crypto is really strong at this moment dude. It's not only that but the adoption keeps growing everyday.
