so it could be a block at spawn or a building that you put some money in and over time it increases by maybe 1% or something, it could also just be a feature of having a town.
Any kind of interest system would be bad for the economy, as it would just hand out money for doing nothing
but if it were a tiny amount and only town owners could do this then there would be less money and it would need to start with a lot of money to gain like 10k in a month.
