Doesn't this seem counter productive? If people stop mining, and the remaining miners get less coins, they will have little incentive to continue mining, so they will stop and move to another coin that is more profitable. Hastening the leave of the remaining people mining because they will get less and less as more and more people leave.
The opposite being, that since it produces more coins if you mine on it with more hash, that it will dilute the value further and make the existing coins worth less.
It's the worst solution I can imagine.
I think too much effort is being focused on getting people to mine the coin. The miners don't make the coin valuable. The miners just dump the coins for cash to pay for expenses. If you want to improve the coin, you have to make consumer focused features. Give people a reason to use the coin or hold the coin. Otherwise you have people just mining worthless coins. Might as well just release all of them to everyone in a lottery and save the environment the wasted electricity.
You'd be better off providing the "bonus" to people who hold coins. That will at least improve the scarcity of the coin and make them more valuable.
I can print paper coins on the copier all day, but they are still worthless.
