I realized what made the freebitcoin website unable to be accessed easily in recent days because it turned out that this casino was included in a website that was blocked by my ISP so I had to access it via VPN to be able to access it perfectly.
All sites containing gambling would be blocked by almost all ISPs in my country. Usually when a site is blocked a positive internet notification will appear but using Brave Browser the notification doesn't appear so I don't know that it has been blocked.
After being a member of this casino for quite a long time, freebitcoin was one of the casinos that could be accessed without a VPN, but now that's not the case anymore, and because FBIN is very VPN friendly, there are no worries about using a VPN.
Be careful, Freebitcoin is VPN friendly unless no other user is using the same VPN address as you. Otherwise you will be unable to claim your free rolls and you'll receive messages saying that someone used the same IP as you
Well, you are very right, but is also interesting to know that even without using VPN, Many of us still encounter the free roll error which sometimes say that someone else have used the same IP to claim as we..
But all the same, it is still very advisable not to use free VPN since that could make the whole matter worst, and also using free VPN to play on several other casinos may result in the system flagging your account for multi accounting which could trigger KYC request from the casino.
