I'm thinking of adding a separate category, bitcoin / crypto casinos on my website
https://allnetent.com/en/What are the best programs for this?
Also who had, any luck promoting Bitcoin Only Casinos?
Do you mean you plan to make a casino that focus only in bitcoin as payment and no other alternative currency ?
You need to considered the fees we have now in sending transaction on btc which is around 1-5$ per transaction its big lost for players mostly those only use small amount money for playing
that's the use of other currency to lessen the fees we need to use for transferring money.
