Yes, going forward... the rewards pool has no ceiling as far as how much value it can distribute everyday, and I imagine the price of Steem will rise a lot faster than inflation will decrease.
I imagine that the function of Steem Dollars will be reevaluated by the community at certain points in the future, especially in the possible event of a US dollar collapse. But I don't see it going anywhere soon.
Hard to predict when the Dollar will collaps, but most likely within the next 10 years.
Yes
If the pool goes to 0 what will happen? Will they need to increase mining output? Make it so there is more steem mined per year?
Still confusing to me honestly.
