Lately, I have noticed in most crypto groups I'm in,  many crypto enthusiasts are increasingly participating in airdrops and crypto events organized by exchanges or project developers to earn USDT or tokens. 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.
