I think of it that way!
During such a crash (yes, it IS a crash!!) lots of people lose their mind and starts to trade bad/ impatient/ make bad decisions!
Now, trading is a zero sum game and whenever you make a trade there is someone on the opposite site, so if you are good at what you are doing and can keep a cool head, I am pretty sure there is a lot of money to be made during such a bearish market!
