wow that's unbelievable, $3500,
i recently just starting to join airdrop since i'm still researching on what coins i will invest.
Good for you you gain a lot, as I join POLYMATH last airdrop and I acquire 250 POLY hopefully it will reach 1.5$-2$ that's a big gain for me rather than having nothing.
Try this one

HAVVEN ICO - a decentralised payment network that utilises a dual token system to reduce price volatility.
check their whitepaper. :-) I'm not saying that you invest on their ICO but atleast join their airdrop. Nothing will be loose
