I am not sure I understand the currency suggestions, or who is suggesting it, but I read @exyle's post and I agree with him.
- Keep the reward system linier and make changes to SMT's on a case-by-case basis instead of making changes to the base code.
P.S. I resteemed @exyle's post.
Yes, that is one of the questions being asked to witnesses, if to change the current linear reward system with a superlinear one. The witnesses seem to agree this is a bad idea (for now).
But there are other changes they seem to agree would be good for the ecosystem. You can see them all (and their votes/comments) here:

@exyle makes a great point, that this should be changed at the SMTs level, and there's no point in even discussing it before SMTs are out.
