So, if I understand correctly, someone with poor math and logic skills has either lost a bunch of money on a gambling dice website or had their kid lose a bunch of money on a gambling dice website?
It is quite plainly obvious to anyone with a basic understanding of maths and statistics, that you cannot beat these games in the long term. None of the so called "strategies" will result in you magically making substantial amounts of money/bitcoin off of games of chance, because they are all "rigged". Just not in the way you think they are. They aren't coded to steal your money by being devious or "cheating". They're pretty up front about what your odds are and what your payouts are going to be.
I have a "free" site that I occasionally waste 5 minutes on because it is fun seeing how long before the classic martingale strategy dies horribly (a loss streak of any more than 10 means you are now over 1000x your original bet, so you either have to start VERY small with a VERY large bankroll and have a no limit game, I start with 1 satoshi
). It is right there in front of me, that should I choose to go with the 2.0 payout, then my odds of winning are only 47.5%. That is a house edge of 2.5%... there is NO WAY you can beat this over a long term of betting. The only way to win at this is to place ONE very large bet, get 2.50000000000001+% lucky, on your ONE roll and walk away with a profit.
If you stick around, the odds will beat you in the end... Games of "skill" however, well... that's a slightly different kettle of fish.
