Just take it as something you can learn from and move on. I'm sure all of us here have missed out on making a massive profit one way or another in cryptocurrency (I for one have), but we're still here and we're all still making money through crypto, even in this bear market. I'd suggest taking a break from gambling if possible, but there's not much else you can do besides moving on from this. PrimeDice's working and there doesn't seem to be anything wrong here- you just happened to lose.
I really like your word. "Move on " same like what i feel when im losing a lot of money and there is anything to do expect just accept it as learning for what i did and move on . and if it feels not right to continue you can stop and still do anything more right to earn money
