A great investor can make money in any market. Doesn't matter if its a bull or a bear. They also have extreme patience and don't get caught in FOMO.
I would consider very few people to be great investors or even good. most just do what everyone else is doing.
Like the investor is so smart to see the movements that will occur from the decline and increase in prices later. It's very much liked by many people not to continue to complain with prices going down.
