I think airdrop is very profitable but for now it is a lot of airdrop and cause useless at all ...
so if you want to follow airdrop should be more selective so as not to get a not valuable airdrop ...
It seems to me that now it is almost impossible to find a airdrop, which will bring profit, but you can try, suddenly you are lucky. In the market that we have now you have the chances of success are very tiny.
