It took me almost a decade and multiple market cycles to learn these 8 crypto lessons. 1. Taking profit is harder than holding through an 80% drop. In a bear market, fear makes holding easy because you think you have nothing left to lose. In a bull market, greed convinces you that a 10x will turn into a 100x. If you don't take profits on the way up, the market will take them for you.(Lark Davis)
