The bear strategy is a bit different than the bull strategy. You sell and wait for the price to drop, so you could buy at a cheaper price.
Or you can just trade in short position, you will make money without need to wait the price down and wait until the price rise.
I think it's the same as you gamble, but when you have bought bitcoin that you used to think was gambling if you hold it for a long time you will realize and know then you know about bitcoin, you are saved from gambling attitude on bitcoin (unless you make a sale because of panic when bitcoin is correcting).
It's already different, if you hold Bitcoin for a long time, you're inventing instead of trading or gambling.
Cryptocurrency trading is a skills-based activity, and how much profit you make depends on your skills and knowledge about the market, unlike gambling that skills don't work, and only luck does this is the situation where a gambler depends solely on his luck to win, but in trading, at last, the trader could speculate his expected profits.
Skills do work in gambling, it just depend on the games you play.
If you play sports or poker, your skills will increase the chance to win, the same thing like trading. Bitcoin or other assets are inevitable with black swan event, if something happen, it can make the price to fall or rise.
