I can see you put a lot of thought in to the "tokenomics" of the project and you are already seeing great support for such a new thing! Burning will really help too.
I do not really understand why you would aim to kill the project in three years? I think that may put people off as they will be worried that it is not a long term thing (3 years will come round very quickly!).
Just saying you are going to "kill" CC has a very negative vibe imo and I would reconsider promoting that as a "feature" of the system.
