Okay, the issue happened with PrimeDice, it is very popular, The amount I lost is actually small it's like 0.4BTC and 2ETH... But here are the details of the issue
This is the server seed and the hashed server seed of my bets
Their provably fair statement said they were using SHA512 to hash the server seed.
This is the hashed result using a SHA512 calculator
As you can see the hash doesn't match... I contacted the support demanding an explanation, this is what they answered:
Basically they told me it was just a typo issue, they gave me a $5 bonus "for letting them know about the mistake". I just don't understand how they claim to be the #1 Bitcoin gambling site and making these kinds of mistakes in such an important section of their website... That's shady for me, and I definitely will never gamble there again.

They specified an invalid SHA512 algorithm instead of SHA256.
This looks like a typo. Although it does not do honor to such a site.
I rechecked the hash with the SHA256 algorithm and it is really correct:
