Either put a entry fee on in which generates some revenue like any normal tournament would do. If you keep paying out more then you bring is is the real issue here.
I'd also like to see more sponsored tournaments from other games etc that sponsor it for branding or can put up their own prices. This is a great "burn" or way to bring revenue back into the game. It should have been implemented long ago and might be too late now.
I don't think there's enough support to bring fees back. I'll make a poll when peakd lets me know the SPS stake weighted polling is ready and we can see what people think. The main reason I wanted to get rid of them in the first place is that they were more or less acting as a tax that no one had approved.
For example, some tournaments had like 20% of the pool relegated to simply refunding entry fees for people that didn't place high enough to get a prize... That means we're giving out 80% of the prizes we have apportioned in the whitepaper. If we want to do that, that's fine but we need a vote to reduce inflation, we don't need an unapproved tax on all tournaments.
I'm definitely open to suggestions on how entry fees could return. Like I said, I'll get a poll up with some options soon, I think the Peakd team is about ready to have SPS stake weighted polling and then I can make more dynamic, multiple choice options.
