This is one of those policies that could either make or break your gambling website. What are the reasons on why you decided to adopt a KYC policy in your withdrawals? Is this being regulated by the country you are setting up? To be honest, lots of potential customers are lost with this implementation alone; I do hope that you at least create a compromise where customers would be able to recover or at least receive a compensation for this.

Though every customer has the free will to decide which gambling website to pursue, with tons of online gambling websites also available in the internet, you are severely limiting your customers; thus reducing your potential profit.
