Primedice was one of the oldest betting site that I know,
It is one of the best and most of the players are kind.
Back when I was still playing there some of the players would have some fun in the chat and tip other player.
It is one of the oldest and one of the most trustworthy casino that you can ever gamble with.
While stake reached it's 4 billion bets, as per title PD has made 29 billion bets and that's no joke.
Primedice was launched in 2013, while Stake was launched only in 2017 so the difference between them is quite big. Anyways I see both of them as being some of the most trustworthy bitcoin gambling websites existing and their team is just incredible doing such a great job with promoting and supporting their projects so well.
