Even if you are saying the truth about BC.game. It’s very hard to prove that by using only the statistics of the result since coin flip is pure random games. I’m not a player of BC.game but this is same scenario with slot games with close source code. It’s very hard to prove if the game is rigged and the only thing we are relying is just the reputation of the casino.
Can you provide proof for the change of algo?
From what op said, I don't think there should be a firm of prove exceo we try it out but op i hate it when people come out to speak ill of others businesses especially in an open space like this which you know isn't right at all.
I haven't used BC games but I've known them on the forum to be cool and I want to know if you ever tried contacting them and I wouldn't have to blame them if there are cases that seem like this because I'm sure they know it will be a bad reputation for them as a company of players always complain of losses and if coin flip which is a random game has such issue, what they would simply do is contact the game provider and that shoukd do the trick.
But there is one thing I've also noticed in gambling, when the losses are getting much, gamblers begin to feel cheated and I hope that's not the case with op.
