I agree with you, straight KYC after registration is sure far better and easier than having to go through KYC after one have won a significant amount of money and wants to withdraw, but the casino insist that the customer must pass kyc verification before his or her withdrawal will be processed.
It's not going to change about the possibility investigation, an unverified account will be asked to submit KYC while the verified account will be asked to submit KYC too with a reason of check whether the account is still controlled by the original owner or not. Even you've submit your KYC, they can ask more and more KYC or they said the images are blur etc.
Depends on what site you are dealing with but in most cases you would really be asked out for more verification on the time that you would really be winning up something significant and this is why it would really be always that ideal that you should only just choose and deal up with those places which are considered to be legit and long time running or simply does have that reputation or else
you are really that putting yourself on great trouble if we do speak about new platforms or not really that so popular. Hitting up huge multipliers or jackpots which is unlikely to happen but if you do have that kind of extreme luck then possibilities are always there, it is really just that on depending on the site that you are dealing with because not all would really be that legit enough on paying up huge wins.
You would really be able to save up yourself on potential problems if you do just simply stick into those companies which does have that history on paying up
huge win or jackpots without strings attached. I do prefer on joining or registering into these platforms rather than into those new ones.
