With so many airdrops right now, it's quite difficult to know whether an airdrop is very good or not. It might even lead to fraud, which is very possible, and we have a hard time detecting it properly.
Airdrops right now are not only introducing new projects that will be created, they have even become an arena for seeking profit alone, so you are right in saying that it is not impossible that some of them want to commit fraud. Anticipation like this, of course, by using a new wallet and not one that we often use, always being careful is the best way to do it.
75% fraud will exist and definitely exist from a comparison of 1:10, and as we know currently the existing airdrops also use daily logins and where participants are required to pay 0.1-0.4$ every day, if multiplied by 1 million users for daily logins alone, the dev has already pocketed a fantastic amount
Actually, the current airdrop has deviated from the first format when it first appeared and was known, but now I agree with you that the greater % is fraud. They start to want to cheat after seeing the enthusiasm for what is happening. If there is a lot of enthusiasm, then the fraud mode starts to be carried out, and it is no wonder they make a lot of profit.
If, as you said, the airdrop uses daily login with participants having to pay, of course it is really necessary to be aware and not follow, but indeed, sometimes many believe that is what makes the airdrop continue to do fraudulent acts.
