Question is, is there an official statement or there is something stated in the terms and conditions that we can use VPN or VPN is allowed when playing at Bitsler giving the benefit of a doubt that the player has no bad intention in using such VPN in logging in at Bitsler.
Generally, there is no problem with using VPN.
But terms and condition says that:
14.1. Having more than 2 accounts is strictly forbidden(by person/IP/house/family).
So, if you use VPN and have a same IP with anther Bitsler user, you might get in trouble. But as examplens said, the probablity of having a same IP with another Bitsler user is very low.
