An airdrop asking for $9 to deposit for KYC? I didn't get you may be but if the above statement is correct, I think the project is a scam one. Why they ask for $9 for KYC while they can simply ask people to complete the KYC? You should certainly avoid this.
KYC was via Coinlist, it is not a free of charge. Dfinity is obv not a scam, lol. Huge VC firms are backing it, Polychain capital, az16 etc.. Tungsten will be now released and airdrop is coming later this year. GL
