Betfurry seems to be accepted in Germany but I'm not sure. You can register on the site and if it is not accepted in your country then you can't even visit the site without vpn so when you visit you can see if the site is accepted in your country or not. And on another side you can check if they keep kyc option for your country if kyc is kept for your country then i don't think any problem if you access the site also using vpn. as I don't live in Germany I don't know the exact information whether Betfurry is acceptable for Germany or not. so you can check yourself
Germany, together with some other countries are restricted on Betfury. Allthough Betfury allows the use of a VPN, I wouldn’t open a new account by using the VPN just to avoid issues. But livechat should be able to help on this issue.
If there's a confirmation that they allow to use VPN while you are restricted country then I think its fine if you use it since they are the one suggested that usage. But to avoid more bigger problem to occur in future while playing much better if we deposit a small amount o ly to avoid problem so that we will not get any issue of balance freezing if this incident happen. But to be sure all of this and validate all to have proof when crazy things happen always reach up their support and ask all about this so that you will have something to present as a proof when some issues happen.
