Actually the only two cases that i found to buy NRVE tokens are to buy a niche or to pay fees for Publications (if there are any others please let me know).
I would like to suggest these two ideas in order to increment the NRVE token value:
1) token burn - burning tokens reduce supply therefore increase token value
2) enabling dividends of some percentage of profit when someone has a certain number of NVRE tokens (for example if someone has 10k tokens he might be able to receive dividends of the 5% or 10% of platform earnings)
3) use them to boost content
4) use NRVE tokens to unlock some premium features
