Agreed, VPN is not recommended to bypass the country restriction by the casino but it is fine/safe enough to bypass the restriction by providers. I was actively playing in duelbits since the first day and I always use VPN when I want to play slot from some specific providers because I cant play it without VPN. At least I have never experienced any effect of using VPN so far although I have never made a huge win (max few thousands $ only).
I don't think you are doing the right thing. You violating the rules of the providers. If providers ask Duelbits to hold your fund and verify a KYC, You will be unable to do that according to your used VPN Country. If they confiscate your funds due to this, You will say they scamming you. A few thousand dollars is a smart amount.
Correct.
Some shitty casino do that, and because of that make me paranoid with that. At least from my experience gambling win a few thousand $ in Duelbits, Stake and Rollbit they are not hold or ask me KYC.
Well, They are in the market to do the business. When you sign up for a casino, You should read the T&C. If you already signed up, that's mean you have accepted the T&C. Since they have the right to ask for KYC (According to their T&C), It doesn't make sense to call them shitty casino.
