Dear Rollbit team.
Have you thought of Shiba Inu? I see Wolf.bet added Shiba Inu on their casino and I think it is a good step from them. Shiba Inu has low price but it is too hot and gamblers would like to bet with as many coins in quantity as possible. Shiba Inu meets this demand from gamblers.
Instead of adding Shiba inu while the famous Dogecoin hasn't been added there yet it's kinda funny to add Shiba without DogeCoin first

Rollbit has fulfilled the complete deposit method BTC, ETH as main coin and LTC as low cost alternative so there is no need for new coins, unless there is a profitable cooperation.
