You probably didnt test/use the site yet coz personally I can say you are lying here. I do use the site and it is one of the fastest out there.
I play there for a long time, and the speed was reduced, now a very slow rate, you need to set 0.0001 Ethereum to speed was quick, but such conditions have on any website with an increase of the bet increases speed, so when they say that they have a quick rate, they're lying, bets fast only for those who play bigger stakes, for all other rates slow . It is impossible to play on small chances, for example, to catch a zero you need six months to turn on 1 Satoshi, and at a bet of 100 Satoshi you will not have enough 10 bitcoins to catch him
