About #1, many casinos have touted this but in the end, it's ultimately to protect the casino's interests.
Are you sure you guys aren't gonna process KYC in case some withdraws or deposits are suspicious?
No KYC requirement I think might not work for a new casino like in some instances where a gambler makes suspicious deposit or withrawal. Most likely, if you stick to that, your casino might not last longer as the house will be taken advantage by some wise gamblers. I suggest do not go for a KYC free the whole time, thats fine with small bettings and small winnings, but for high rollers that are also capable for big winnings, you can always require for KYC like established casinos do.
We are going to take normal small bets at the beginning >$100 when we have a big bankroll maybe we can start incrementing the account limits for high rollers
