I faced an issue in Primedice that as of now doesn't allow me to verify bets. But please don't take this as FUD!
Currently on Primedice due to some errors on their side users can't verify bets.

In order to verify your bet you need to reveal the hash by creating a new one and then click on your bet. But right now they have acknowledged that there is an error on their side and users can't see the more info required to verify when clicking on their bets.

Anyway, just a heads up. Probably and hopefully they'll fix it sooner or later and users will be able to verify their bets. Old and new.
