I get it why there is no need for house edge, its because you are basically betting against him. The problem with this is that if someone programs a bot with their API (if they ever release one), it will spam thousands of bets and the net win result will be basically 50/50 since as spins -> infinity then the wins of red or black are either.

However if its just for a few bets then it should be fine for now at least. Since this site just launched a few hours ago.

However the no provably fair issue is a huge deal breaker. You need to prove the bets or else this is another Yobit dice type of site. Where its impossible to tell if you lost by bad luck or were cheated.

Another issue is with the max bet. You need to use risk according to your in house capital so you don't end up going insolvent.
