Based on alot of people talking about it, I've come to the conclusion (that may be wrong) that PrimeDice is the most popular bitcoin casino. But why? I can't use primedice in my country, so I don't know.
Is it the community?
Is it the increasing faucet?
Is it the good looks?
Is it the good reviews?
Is it the knowledge that they've survived more than a million dollars in loss?
Basically Primedice is considered the best due to some basic reasons, which are :
1) Fluent transactions
2) Brilliant and effective layout and user interface
3) Trusted staff and very old site.
