KYC is often used as a scam tactic!
Because if you lose (even millions) they will never ask for KYC and give your losses back.

Witty but I don't agree.
List of sites asks for KYC if you win the big amount.
- STAKE
- PRIMEDICE
- FORTUNE-JACK
These sites are reputable and made a good reputation to all. So I think that there is no scam tactic in here.
