replying here due to nesting:
Most investors, potential or otherwise, would like to have their investment have value. A change in the curation system would be a change in the rules to give investors more for their money. Thats not instability, its value.
There is only one type of investor who would be negatively impacted by such a change. I hate to use the N word, but i think here its appropriate.
Ninjas. The people who have millions or tens of millions in SP because of the "ninja mine" that wasnt really a premine or an instamine, it just had precisely the same effect as either of these things.
I know i know. They invested sweat equity. so theyre investors too. But if you give the sweat investors all the return, and the money investors none of it... well.. what incentive is there for money investors.
