This doesnt prove anything. You have to admit that there is a posibility that i only have an account and a friend that recommended me ur site sent me the btc.
There’s a possibility too that it’s your mom but since that you are playing in online casino. An evidence such as similarity on IP and account history is enough evidence to tag your account as multiple account.
Your reason is already used by many user that being accused with same issue. Whether you are saying the truth or not. The evidence is very strong in an online case.
