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.
I guess that was an honest typo, but really? Only $5 as a compensation? That is a big typo to be honest. People can claim that the hashes they were provided were totally invalid. and can probably even sue them. What is more funny is that almost 24 hours have crossed and they still haven't fixed the typo! They are not even taking this typo seriously lol.
Indeed. He should tell the name of the site, so we could help him to make some valid proof that the gambling site he assume that is cheating is true. Instead of calling a lawyer first, he should definitely ask help from other people to make a valid evidence, so that his accusations would not be too embarrassing.
