Of course, everyone should take advantage of every situation, not just crypto exchanges hacks, there are news that can down the market, for instance the covid-19 scare last year. If average joes and institutions have bought bitcoin that time, then for sure they are in the profits as of today. But since we are in a bullish cycle, then bears should wait, don't try to short bitcoin as you will get REKT.
It is true that I experienced it when Covid 19, the drop in the price of crypto in the market dropped drastically, so at that time the confidence in crypto initially declined, but a few months later in late December Bitcoin proved it by sustaining the initial surge that made people views on crypto start to rise. restoring and trusting crypto is one way to save assets. on the other hand, hacking exploits the current condition as if playing with prices. there is their interference behind all this.
