What kind of airdrop is this? OKX randomly sent 5,500 NIGHT tokens. @star_okx Can you make it clearer? We're so confused, asking around everywhere. We want to brag about it, but don't even know how to do it properly. Always quietly handing out benefits every day. @okxchinese @Haiteng_okx @Cryptosis9_OKX @Mercy_okx @mia_okx
