Technically, regarding the KCY procedures, level one for me would fine
KYC level 1 is usually still very basic even sometimes does not require any documents and I have checked directly in my account there are really no documents required, but players must be careful in filling out all information because it is very possible if you are gambler that use large funds will be asked to meet the next KYC level who need documents and must definitely be in accordance with the information that has been first filled by the user.
most people just play on a gambling site for fun and don't think they will get a big jackpot, so when they withdraw big money they are surprised that the next stage of KYC must be filled, but i see gamddom will not do that, they will still be able to process your withdrawals in large amounts and without KYC.
