have you ever found a scam project or airdrop?
what wil you do after working the project for a couple of week, but you get nothing..?
that was one of my reason to keep working on another project at the same time, doing that wouldn't waste your time to stay awake on those project, watch their group or anything else.
in my experience, 4 of 10 token from airdrop already landing to my wallet (of course it also depends on when they distribute)
