Yeah, the exchange wallet part is probably what gets overlooked the most. Sending crypto back to the same address sounds simple enough, but with exchanges its not always that easy. Funds might not even get credited properly.
And I agree, the 1x rule itself isnt really the issue. Its finding out about it when your withdrawal is already pending. A simple warning before depositing would save a lot of confusion and complaints imo.
Good explanation. I think most players see the provably fair label and just assume everything is fine without actually checking anything.
Saving the original server seed hash is a pretty important part too. Otherwise you're still trusting whatever the casino shows you later. And tbh I doubt many people even bother using these verification tools.
Also worth remembering that provably fair doesnt mean the whole casino is trustworthy. Fair game results and reliable withdrawals are two different things. Still nice to see casinos making this stuff easier to check.
