Play on proven sites. Because now there is a bunch of bitcoin casinos / dices that deceive people.
On which site did you play?
oh man, this is Bitsler, it's clearly shown from that image. Of course there is no doubt bitsler is in list of proven dice websites, it even has so much traffic and it's so popular, believe me if bitsler isn't fair, it wouldn't be so popular.
You can verify rolls, also when you play dice there is some perxent of loss even when you bet for 10 times and chanse of win was 50%. It happens..
