Yes, providing incorrect data can endanger the player's position, maybe many players only play with small values and never think about winning big but what if that happens and the security system from Roobet asks the player to do the next level KYC and this will become a problem or what if in the future Roobet changes the rules there will be a withdrawal limit from each KYC level, so be careful in acting to avoid unpleasant things in the future
If a platform has flexible KYC rule, it means you should afford risk of higher KYC level will be required in future. Create your account, deposit money and bet with the risk in your mind.
It does not mean they are scammer or including such rules to scam you in future. They only require higher KYC (if they are not scammers) if they detect suspicious things from your account (cheating, same pattern of betting big and win big, etc.) or money laundering on their platform. In my opinion, if you are good user, you can surpass their additional KYC requirement.
Anyway, always remember, not your keys not your coins and KYC is dangerous, on any platform.
