Quarkchain has finished its ICO long ago. Just out of curiosity, why are they making an Airdrop now?
Quarkchain already make bounty airdrop since December 2018 : https://bitcointalksearch.org/topic/bounty-closed1000000-qkc-rewards-quarkchain-5085884 (Round 1 Airdrop)
And in March Quarkchain make a Round 2 Airdrop : https://quarkchain.io/quarkchain-bounty-program-round-2/
i think they want people over world know about Quarkchain, Especially the qpocket wallet, download in qpocket.io.
Qpocket now Fully support TRON - TRX, BTT, TRC10, TRC20 and all the DApps running on TRON. Qpocket will support more native token using QuarkChain’s Boson consensus,

So i recommend to invest in quarkchain for long time, but you can get free token too from airdrop and hold it like me
When Quarkchain bounty campaign has started, QKC price was about 950 sats. But is about 300-350 sats now.
So it is not good to distribute bounty tokens so late.
Quarkchain bounty in my post start in Early March (Round 2 Bounty Campaign), but if you want join new bounty campaign. You can join the Origin Protocol campaign at number 4, It's same as Dfinity Airdrop but the worth of airdrop not so high like Dfinity Airdrop.
