Verifying later on is a good practice for privacy, while the other way around is assumption of having a security of the deposit and future withdrawals. Where in fact your account can be locked even though you are already kyc verified, since your KYC is not the only thing they will look at when there's a "suspicious" activity on the account. For those users who have single playing casino, that's good, not for those who have multiple casinos. Why people plays in different casino? Simply because they don't share the same odds, games, game provider, etc.
Even if someone uses multiple platforms, they should only go with the ones that are the most trusted and reputable platforms so that they don't face any issues when they do their KYC verification with them. When you are doing KYC verification on a platform that is new in the market and you haven't heard any reviews about it yet, you will surely not have peace of mind and you will feel like your identity documents and personal information might be misused.
So, when a gambler wants to try different games or see better odds at a different platform, they should first make sure that the platform is trusted and then they can go for it. If they want to try a new platform, they don't need to do KYC at first but shouldn't deposit a lot of money.
You're absolutely right to exercise caution while using platforms, particularly those that are brand-new and haven't shown their utility. I've watched companies come and go; some are legitimate, some aren't so much
To put it bluntly, KYC is garbage. A total, total, irrefutable trash. Alright, so what? If we want to play the game in this contemporary environment, we have to accept this garbage. It's an evil that's essential, yet neither you nor I love it
For the gamblers you alluded to, intelligence is paramount. Sure, give the new games a try and relish the rush of a good wager, but always, always, exercise caution when it comes to where you invest your money. As you said, scout the area before jumping in headlong. Use the excellent judgment you possess and resist the temptation to be duped by any platform
