Is there a way to limit/turn off roll animation when rolling single bets? I find it unnecessary long an annoying after some time.
I read in your ToS that: "For safety, we store a limited amount of bitcoins in our hot wallet." - how high is this amount exactly?
Nope, you can't turn off the animation.
Sorry, but I can't answer to your question. The information about amount of bitcoins on our hot wallet is confidential.
