It is an airdrop so how can it be a scam? There is no way to guarantee the price of a coin wont drop. In any case, altcoins are in red, perhaps you want to wait to see whether the price increase.
That are indeed my thoughts. Everyone is calling something a "scam" even if they get it for free. So funny world...
Like I said, it is not just money that can be involved in a scam. It is also your personal data that can be obtained through it. Even though you are getting it for free but realistically you are still "buying" the tokens with some of your personal assets.
