It's better to earn real tokens, not fake ones as most of these ICO's are scams and they promise in any method to scam people. I joined so many Airdrops, bounties, but only 2 to 3 paid me and they were in less price. I wasted my time by promoting them on Social media sites.
I suggest you to discover much, but after all these also they don't pay anything for us.
why give up now, crypto has been at its peak, its in their prime, so dont surrender mate, theres a lot to be discovered for in this crypto world
