Many many complications, lol. It even got to an extent that even many scam air drop would give one task to do in promise to deliver air drop and then on the sale date they would ask one to make some deposit to claim the whole air drop
This is one of the main reasons why I am absolutely not interested in Air Drops at all. Even the legit Air Drops would pay in tokens that have no value at all. In the end, you just suffer.
