Whenever you want to build provably game but as long as ponzi scheme exist, you will never build a provably fair ponzi.
As we know Ponzi scheme will scam people in the end.
Better gambling it rather invest into ponzi
This is exactly what I disagree with. You call losing your deposit a scam. Well if you gamble enough with a legit gambling site, you will also lose your stake. In both cases you lose everything, yet one is ok and the other isn't. In both cases you also have a risk of being scammed by an operator, but one is okay and the other isn't?
