Going to ignore the first half of your message because its just you being smug and contradicting the lower half of your message.
(Seriously how are you still trying to argue about provably fair while I never said it was the problem?)

But yes! Perfect justdice quote, now we're getting somewhere!

So let me recapitulate, you're telling me that after all the security and provably fair mishmash, in the end, justdice uses the last 3 bytes of the hmac output, creates a number, and divides it by 10k? This part right here buddy, that you need to verify every time you want to trust a website.

Sure, im very sure justdice are legit. But you could EASILY, for example instead of divide by 10k and get the dice roll, you divide and substract 5 every time. Or use modulo to turn every nth number into a 0 bet... Oh and flash news, YOU WOULD GET THE SAME RIGGED OUTCOME EVERY TIME. So where can you check that they dont do this? You need to read the verifier source code.

If the verifier isnt open sourced, you cannot prove that the website isnt scalping the house edge. Even if it is open source, you need to verify that the part where the hex output becomes a bet roll is uniformly distributed on the target interval.

Bitsler and Primedice can cheat you with false and misleading claiming that you breached their terms and conditions and confiscate your account balance, like it happened thousands of times in the online gaming history!

I am not an expert but I consider that this fact lies in the differentiation between private and public hash. If you don't use your private HASH then when placing the bet you will get a random public HASH. Given that, I understand that when in a private hash there is a possibility of getting the same number 1/101 in a public hash this probability is different and eventually it may lead you to a loss (talking about Dice).

I repeat that I am not an expert it is just my own assumption.

I saw the website and was interested because I was planning to make a Youtube video going all in on live roulette, and I did, I deposited 350 and played I won almost 600 dollars, then I withdrew my balance, I decided later in the day that I was going to go all in with the 600 dollars so I did I played and won double ( was feeling super lucky), so basically now I got 1200$ of balance so I decided to withdraw, my withdrawal was denied so I talked to support and they told me to email the security email, they asked for id proof and address proof, which I provided, and it was accepted, after that they asked for KYC procedure, so I did that and it was also accepted but they sent me this in email:

I have no idea why this happened, it's honestly very unprofessional and a complete scam from my perspective, I have done nothing to violate the terms and conditions, yet I get banned for some random shit I have no clue about, this does not make any sense and very unfair.
