That's NOT the whole story ser. The WHOLE story is also hearing the reasons WHY the casino is blocking the withdrawals of those users. Because, there's definitely a reason WHY it's happening. This isn't a mere "let's scam these users and get their coins". There's a reason for it.
This is the fact but is just that the compliance team hasn't given a clear response why this user withdrawal has been halted.
I don't really see this user as not being guilty but if the Rollbit compliance team doesn't give clearer reason for this, I guess that mau be taken as he/she is not guilty and this isn't good for the solid reputation they have.
