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.
