The table only confirms what I said, we are talking about mathematical probabilities, not abstract things, most of the spins were always 50 sats/points/tickets, with a FUN price of 50, today the spins are 17/18 sats/points/tickets with a FUN price of 4, so the site should pay up to 4 times more than what it was paying, and it is no longer sustainable, especially that for now the investments on FUN are blocked.
Even if most of the rewards are the base amount, the 5000 amount rewards still made up a proportionately greater share of your total rewards based on the original odds. Below is the chart of what the rewards were when they debuted the premium membership. It shows the second tier and third tier rewards had 10x and 13x greater chances of being rolled compared to the current chart.
Because they charge a premium for every token sold, the current cost is 7 sats and to become a level 1 premium member it would cost 17,500 sats. When the token was 50 sats and they charged 51 sats on FBC, it cost 127,500 sats. The cost was 7x higher back then but the rewards were expected to be 11x higher. As high as the price was back then, we could recoup our investment faster.
The ratio of rewards received to investment amount is not higher today than it was at the beginning, but it might be higher than at some other point after they adjusted the odds, presumably to keep the program sustainable. Other factors such as declining popularity of the website might also be contributing to its current unsustainability.
