I wondered the same thing too. I'm not certain but it looks like ~1k-2k/month minted for POS rewards. If rewards stop entirely network security could become an issue.
That is true so maybe the team can come up with a new max supply like a few million coins or we just keep going like we have for the past year. The circulating supply is still low compared to most other coins out there but I do know that a lot of people like to know what the max supply will be.
