The price of an existing Luna coin can only increase if the Circulating Supply decreases. This can be implemented by forking or buying coins from the market and further burning. It looks like the team decided to implement the first scenario, time will tell how successful it will be.
The supply will not decrease because the team is not optimistic about burning tokens based on requests from the community, the team only provides the burning address but the team itself does not send Luna to that address not even suggest for users to burn their tokens, I don't know what the team plans for the best decision for communities other than the Luna token version 2.
