Have you ever proven fairness of a game yourself or know someone who has or do you simply trust a casino claiming their games are provably fair?
Why would you ever trust a casino without testing their provably fair method?
Not sure how long you have been in this niche of gambling with cryptocurrencies, but the term trust here does not make sense without being able to be verified. Thats why most casinos that have been running for long have a transparent method to use a third part verifier to verify your bets.
It is very simple and if ever you find a casino which lacks such a verification method that you can use or straight up does not mention anything about it, you can be sure that the site is a scam and immediately report it here in this forum in the "Scam Accusations" section for public reference.
