An airdrop program now has change a lot. People can not easily get their reward before they do the task. Yes, the participant must do a long process and time to waiting the distribution of the reward needs a long time.
But that doesn't stop people to trying to participate on the airdrop. I don't have any good list of the airdrop programs because I think those airdrop will have the similar task. That makes confusing to join or even to just following the project.
People can frustrate when they see the project turn into a scam as many project already like that. They will think that what they do so far is just waste their time. This time they will not easily to get the good airdrop that can give them money.
Indeed, getting airdrop prizes is getting more and more difficult even though the task is simple, but it takes a long time to do it, that's something natural considering that there are so many airdrop followers at the moment, and the need for precision in choosing an airdrop before starting, that's what needs to be considered.
