For the sake of the social contract it can't be 1% or higher, anything equal or bellow 0,999% is valid.
Please elaborate. I feel like maybe there's something I'm not understanding.
If you read the first post on this topic it says:
[2] Proposed: minimum maintenance reward of <1%/year for mining incentive starting after approximately 8 years.
1. can you see that at the moment is just proposed?
most likely will not be definitive 2. if says after 8 years, the problem is that we can't be sure if after 8 years the coin will be still alive so why are you always thinking that far?
Because crypto is not just backed by math or cryptography, its monetary rules are set in stone, it can't be changed later.
