I like primedice. but wait for more than 30 minutes with average transaction fee but still no one confirmation. No time to waste on primedice today anymore. I will play tomorrow when it reaches my pd account.
That's an issue we can't help with.
Try adding a larger TX fee next time if blocks are being mined and you aren't having your TX's confirmed.
Why not make it so you can play instantly but you can't withdraw before 1 or 3 confirmations?
If it works like that, malicious users could deposit bitcoin and go all in immediately. If the bet loses, they can try their best to double spend the unconfirmed deposit transaction, and if the bet wins, they will just wait for a few confirmations, withdraw the bitcoin, and repeat it again.
