Hey, @d-zero.
I wonder if there's a way to identify or differentiate between power ups that come through investment and power ups that come through rewards? If having money liquid as soon as possible is the issue, my guess is, people want to be able to take most or all of their invested money out, but might not mind having the earned SP through rewards still there.
Probably just as tricky as your choose your weeks idea, but regardless, I don't know if it's really going to get us anywhere to change it to four weeks, when what people really want is to be able to draw it out on demand. Regardless, even there you're waiting a week for the first of the four to divest, which can seem like an awfully long time the way the crypto markets can be.
