Is this a comparison to choose correctly between gambling and trading. By definition, it is much different. But it seems the OP is confused because nowadays there are not a few exchange excuses that are in the name of trading but in it is gambling. Like a trading platform but the point is that it only includes gambling.
Maybe it's such a concept that ends up getting the OP confused and asking which one is more profitable. For me both are profitable if really in different conditions. Gamble profit when you are lucky, trade lucky when you make profit. On the other hand, there are quite strong differences. Gambling if you lose, it's all gone, but when trading if you are faced with a bear market, you lose nothing as long as you don't sell.
The problem is how smart are we to choose which is much more rewarding/gambling or trading crypto? Define !!!
