So far I haven't received a better payoff airdrop. Just a bunch of useless tokens I have been receiving from airdrops.
It will be difficult for us to see what happened in 2017 about airdrop to happen again. Presently now, airdrops are worthless. You'll be promised a $15 worth of airdrop, at the end will be receiving a $0.04 token. It's so annoying
You should keep yourself from enrolling into airdrop that's coming from less popular project.
The succesfull airdrop usually comes up with many hype and that way you can sell the airdrop token at high price because of the hype. However, it's true that 98% of airdrop are just worthless token so it's normal if you never encounter any valuable ones.
