Since it's a "decent" amount you are planning to deposit, you will really trigger the site's KYC-related stuff or such forms of verification.

A decent deposit will really be subject related to money laundering, especially for a gambling site that is legally registered and complying with the gambling laws. What you need to do from there is to actively play on that site and established a decent amount too of wagering amount.

But honestly, as long as the site we are talking is reputable, don't mind complying with the KYC if it's really necessary to do so.
