Betting on shifting prices of cryptocurrency market is nothing but gamble. It's not trading.
It is like you would say that by sportbetting you are engaged in sports activities.
Trading - earn money in long run
Gambling - lose money in long run.
I don't know how someone can say it's the same thing.
You are right about gambling here, if you play long enough you will most likely lose, but trading is not a complete opposite of that.
I personally know newbie traders who lost more money by trading that I lost by gambling.
