It so happens that the account has finances in Ethereum. I would like to use it on betting. Can you tell me which bookmakers work with such finances?

The one who knows on this issue, will definitely be able to tell you something. I am not very well oriented in this matter. But if I am not mistaken, eth betting can be tried to open using one of the links that are presented on the site https://betclone.com/crypto/eth.shtml Have a look, I think you will be able to find something suitable.
