I would be very careful about selling any crypto gambling accounts because some of the online casinos do not look kindly on such things. If I were you, I would read the account conditions from the online casino website before attempting to do anything that may or may not get your account banned, as well as your funds frozen. It happens more than people think and I myself would not risk it.
That's right, the risk is too great if such a thing happened.
better to keep than when it happens then everything will be lost.
on the other hand of course there will be a reason why the account is banned, is there something there the OP doesn't explain in detail.
but whatever it is, I think reading the provisions first is a good decision so that later when it can be traded, there will be no impact there.
