20 people were supposed to win. In the next season, if you win and take the first place, I suggest that you change the rules 10 rounds before the end when you know more or less who won to change the pot only for the winner.
I do not see anywhere in what you shared that it was explicitly stated there would be 20 winners. Nothing was set in stone from the beginning, it was all dependent on how many players joined the pool at the end of the day:
The first place jackpot prize will be a guaranteed 0.1BTC and then the rest of the money will be split between 2nd-10th places. If we get 50 users signing up that will be a further 0.125 in the pot so there should be over 0.3 in total.
This suggests more that we should have expected 10 winners from the get go.
