I’m personally playing Notcoin and HotStrike right now (is just launching, so I think there’s a chance to earn something early on.) But, as many here have mentioned, you won’t get stable earnings from these games; it’s more entertainment than a source of income.
I know one of my colleague who spent his 7 months tapping in these airdrop game for collecting golden colored looking coin hopium for earning huge but at the end he gat coin worth around 11 dollars but his expectation was least 50 dollars and surprisingly the allocations of coin was given more on bases of referrals which the many youtubers and celebrities who referred many users by their referral link earned more than a regular users who spent more time in it now he don’t believe in these scheme anymore afterwards. If you want to make 5-7 worth of dollars with these airdrops project then you can join using it in your free time but joining on purpose of earning more than like said stable huge income then don’t jump it, will only be waste of your time OP.
