I don't agree with you that this is one of the best online casinos. They managed to be the first to introduce a game system using cryptocurrency, but they didn't think about the safety of their customers. Login to their site is forbidden for many countries and VPN in this case rarely helps. This is a commercial platform that simply steals money from people. Gambling is prohibited in my country, which is why I've always been interested in bitcoin poker and still make a living from it. I advise you to give up low-quality sites so that you can finally start earning a lot of money!
Best or not is absolutely about personal preferences, someone may say a site is the best but other one may say the site is not the best.
It might be not the best for you maybe because you cant access it without VPN, can you?
Gambling is also prohibited in my country but I still able to access and play in most bitcoin casinos out there including roobet.
