its hard for me as well as to how some of these sites would not be able to fake and cheat easily as a good chunk do not know how to check and all the details behind doing so.
Im looking to do my own little small betting over outcomes on this we both know would be fair.
That's why you should always need to choose the well-reputed sites to gamble because these reputed sites know that they can make a good profit in the longer run without cheating people. As long as gamblers play these games longer then surely these gambling houses are going to make a lot of money and that's why they will not try to cheap players for small amounts.
Sometimes sites are cheating and just not caught like I remember a site did that, they used to skip the seeds somehow and scam site, while they were highly reputed. Can't recall their name but yeah truly trusted until then.
I believe for this same reason we should more gamble on sports than in dice, because the verification system is quite complex and we can't just verify each bet using that long and tiring procedure.
