I want BC.Game to come up with a solution, like:
Allowing conversion to digital currency (BTC, USDT, etc.)
Allowing withdrawal in a different way
Or any other useful way for me to get to my money
I feel sorry for your loss, but also feel sorry to inform you that your money possibly has gone forever. This becomes a usual practice of bc.game to scam funds with every way possible. I say this without asking for evidences or tagging the rep here because the details says it all. You are allowed to register and complete KYC and make deposits using your bank account or payment card whatever, then suddenly popup your country is restricted. At least they should refund you the initial deposit if they are honest enough, but unfortunetly they won't. I hope you didn't lost so much funds.
Check this board about pending issues with bc.game and you will find plenty of them. Some cases got resolved but this is due to several possible reasons. It is a selective scam.
