Hello Crypto, personally I can tell you that I was a tradder, hunting airdrops, it was something too exhausting for me, it was very difficult to find a place that accepted the exchange and at the same time it looked bad, because they gave those "gifts" with the Intention to support your project, but the vast majority just wanted to get out and out of there.
Generally, those who give them, block them for a while, some "invest and buy the token" that increases their value, but then the same day, in a matter of seconds, they release the change or withdrawal, people go crazy, changing and selling and that causes his fall from which he hardly recovers.
So many promotions end up being scams, they offer and they say they are stable and good projects, people invest and then they leave with all the profits, they disappear, personally I understood that in both parts it is scam, I do not like the airdrops, I prefer the projects that consolidate at once, instead of those that offer a lot and end up giving little or nothing, or do what everyone does, change, charge and forget about that page, this last is just as ugly.
