Same as last season, yes, that info was discussed but never finalized. Last season we had IIRC 50+ players and discussed for 20 prize spots, but in the end it became 10, and actually we only discovered the prize amounts after the competition ended.
Here is the sign up thread for last season
[1], I think it was made very clear that we will have ten winners:
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.
Right, but I think it's possible that the prize will be shared between more than 10 users.
This is also from the sign-up topic posted by sign up thread.
The payouts for last season were as follows and this season will be similar but of course it all depends on how many people play but it will be between 10-20 max:
I am not sure, but since we have more than 50 users in the pool, we may have more than 10 winners.
