Legit but limited airdrops i would say, at least with coinmarketcap airdrop you won't get scared of wasting time with scam project unlike other airdrop source that promote all the shit project that are worthless, i wonder why op is so kin on looking for airdrop sites and groups because nowadays you can hardly receive anything meaningful form this random airdrops, unlike before, airdrop of this days are not worth the trouble, better to engage in doing bounty, work for it and get some reward if you get lucky.
