Investors will have their rewards reduced from 90% to 15% of the pool.
That's incorrect. SP holders didn't get any rewards in the first place. They were debased by about 10% , with the recent proposals they will be debased by only 8.5% , this proposal is beneficial to steem power holders.
You are confusing the reward pool with debasement. My statement was correct.
Bitcoin miners are constantly debased, technically, but their rewards make up for the debasement if they can sell their rewards for more than it cost to produce them.
Not confusing anything.
I'm guessing you are talking about the inflation here which is anything but a reward.
Your statement is incorrect for multiples reasons.
They will actually have less inflation with the new proposals.
