Territory fees are a tough one aswell. Drop em too low and you'll get a bunch of waste territories. They need to be that right balance of affordable, sustainable but also prohibitive enough so as to not flood SN with pop-up territories. Perhaps a sliding model would be more appropriate, and yes have a high start up cost like 100ksats. But from then on, the bill is a percentage of revenue generated by the territory. As it stands SN rewards pool gets 50% daily. Perhaps a fee of say 20% of overall territory income per month? This is just numbers plucked from the sky. It's not too similar for brick and mortar rents. Larger businesses require more space (and generate larger incomes) their tax is higher and their rental is higher for a larger space. For a small business occupying a small portion of that real estate, the rent would be smaller. It's like renting an office rather than paying for the whole office block.
My own posts aside. As it stands in music I'd see 2-3 daily threads from various names. I'd have to make the posting fees 1666 per post to break even. All that's going to do is create a ghost town of zero posts because no one will pay that to make their post.
I'm curious as to how fees are going to adjust and adapt (if at all). But 100k deposit for a at best so far 3k return per month... That's not smart investing that's sunk cost and chasing losses.
