I'm still a non-kyc user,
In case of account opening or gambling Bitseller doesn't ask KYC documents to its users. And KYC verification is not mandatory for deposits or withdrawals. However, if you make large deposits or withdrawals, KYC documents may require to protect your funds,
In other words, if you win a large amount in bet, they reserve the right to ask for KYC documents to verify your authenticity.
Better read their TOS to know about it.
Most of the time it happens, casino ask KYC verification when gamblers withdraw a huge amount of money, also if the site suspects your account of doing some unexplained activities, better to read everything from the site house rules. It's really annoying when you suffer from
this kind of concern.
Personally, I only use a small amount of money to gamble. I never have any issue with KYC as long as the site has a good reputation.
That's right, as long as the gambling site has a good reputation, you should not have a problem submitting your KYC, the words "they reserve the right to demand for kyc anytime" should make the gambler aware that anytime the site would ask for a KYC requirement regardless of their reasons.
