If we knew what happened in the last cycle we will avoid holding altcoins when bear market comes. No altcoins will go higher when the bear market starts, even Eth, Sol, and BNB will join the bearish movement. Because of that, I will never hold any alts when the bearish is starting because no one can overcome the selling pressure even the best coin in the world which is Bitcoin. Invest only when the bullish market starts or if still bullish.
