I participated in more than 200 airdrops this month, but I received payment only from 6 projects. And I think that this is a good result.
And all that 6 projects were $0 coins or not presented on the exchange?

i dunno why you guys spend your time on such trash like airdrops
You talk only from airdrops who do not pay...
Why do you not talk about my WSPU2 airdrop faucet where you are sure to be paid?
My airdrop is the only airdrop where you are paid if you want to be paid before you get your WSPU2 token.
Why is my WSPU2 airdrop not interesting for people?
Because it is a real token based on economy and not a scam token where many many dollars are promised in advance.
With my token system you get reality...and so far rality is only worth $0.0035 or so.
And once the WSPU2 is worth $0.01 or more you will say to yourself:
Why have I not claim for free the WSPU2 when they was only worth $0.0035 or so?
But so is life...
Don't get me wrong, but I think you must be thankful that you didn't put money on it. But then not ALL airdrops are in fraud, or scams. It is depends upon the project if it's legitimate or not. From now on, you should be very careful in investing money not only in airdrops but in all.
