I like the simplicity of multidice.
Bankroll still isn't that much because you're just starting out. The fee of 0% is good as start to attract more players and investors.
They have 35+ currencies, means they have 35+ different bankroll so basically they have to divide their funds for the bankroll. I am not sure how much is the total bankroll if we sum all the bankroll of each currency but I guess the bankroll will look bigger if they have less currencies.
I've looked into their stats of what they've actually shown and that's not really that much.
Even if they're supporting a lot of currencies and payment method, they're transparent and honest with what they're showing. Well, every good casino started out from small bankroll until they've got a lot when they became big.
