Just make sure that you are just using small amount of capital, it's very likely to submit verification
when you have huge amount of money to withdraw.
That's typically the scenario with most gambling sites. Some sites don't require Know Your Customer (KYC) verification initially, but once you start winning significant amounts, they may trigger the KYC process. Currently, most of the gambling sites I play on do not require KYC. However, I have familiarized myself with the information in case they do require it. You are correct that we should not invest a large amount of capital as it could be compromised if we fail to meet the KYC requirements.
if casinos declared that they will collect KYC, this doesnt mean that they will collect it early on. It is a nice thing that there are casino that only collect KYC when there are rediculous amount of money that is being taken out from their casino or if there are unusual activity on the account. Many gamblers are spared from doing KYC even if it is required. I myself only submitted a KYC on a separate casino twice even though I play on different casino. If my information is leaked, there's only two casinos to blame.
