This airdrop is for anyone who completes the tasks as joining Playkey's Telegram, for example.
Later there will be a second airdrop, to Castle coin holders.
Both airdrops are managed by Castle, which is soon going to release an Airdrop Platform.
I suggest you to join Castle's Discord chat to learn more ;)
