With races prize pool cut you should also cut number of players that receive reward to top ten positions, more for those who wager the most.
They actually recently increased the winner number from top 30 to top 50 actually making even more people to win something while also dropping the prize amount. I think that makes more sense because you are not giving some people a lot of money but you are giving a lot of people some money, that way they could call on a lot more people to try.
There are only a handful of people who could win the top prize, yet there are a ton of people who could race for the 50th spot, combine all of those people who race to be in the top 50, that would mean a lot more money would be wagered combined compared to just the top 10 people who would gamble anyway and a lot anyway, involving more people would benefit wolf.bet a lot.
Or maybe this is a wrong decision making and they won't and eventually change back, only time will tell.
