Just curious, do you have any proven track record or similar file for showing the profitability of the joined airdrops? I have seen Russian based airdrop lists but the majority of the lists were useless. The admins hire the programmer for writing the simple script and they put referral links for milking other airdrop hunters, this is what I have seen in the similar sites or services.
Due to the situation on cryptocurrency market, many airdrops are just worthless or projects are not even started out.
On my website/list I'm trying to post only the best ones (that's why there are fewer than on many lists) = projects which may achieve something in crypto space.
Big airdrops which really paid (I remember or I participated): BOMB, Atomic Wallet, Velic x ICON, Keybase x Stellar Foundation, all Binance airdrops, KuCoinPlay.
