Is it because these "people" are afraid to trade or they do not believe they can make money from trading? Don't get me wrong, I understand that this can also generate passive income, but what I'm curious about is whether these activities truly yield significant profits or not.
They are simply afraid to losing their money, especially most of the users that participated in airdrop campaigns come from 3rd world country and they really can't afford money to do trade, hence they joined most or even all of the campaigns available out there for some not guaranteed pennies. Even then they get the rewards from there, they just sell it right away after they get the reward. If you call that trading then sure.
