Interesting stuff. Thanks for thinking outside the box.
Regarding regular burning, I think it's a nonsensical idea. Why create them in the first place if you are going to burn them? Do we see anyone burning their fiat notes? Would you do that? I know I wouldn't.
I'm a fan of the idea of a variable powerdown, with Hive Power that is locked longer (subject to a longer powerdown period) gaining access to greater rewards. So greater curation reward, and greater interest via newly created Hive. Permanently locking up Hive such as in the case of your PHP could be another step in the reward incentive.
My thought exactly. Why not lower the overall cap instead? You could even change them to be burned before distributed by allocating a % to @null, right?
True, even if not permanent, having a longer power down with greater rewards is an excellent idea to test I believe. The longer your commitment, the more stable the ecosystem, and that should merit greater rewards.
Thanks for the feedback!
