So the more MicroCash you have the higher the percentage of the fees you get. It doesn't necessarily reward early adopters, it rewards people who have MicroCash.
MicroCash: Taking from the poor and giving to the rich.
Interesting.
If I understand correctly, if an address has a greater-than-average amount of currency then it will get interest.
Paid for by all the accounts with a less-than-average amount of currency.
So there's an incentive for everybody to (try to) be above the average. That seems like a recipe for a lot of disappointed people, especially since a graph of size-of-account will have a long tail with of lots of little accounts.
Making a half-thought-out-prediction, I'd say the end result would likely be one big centralized account controlled by the largest exchange with over 50% of the currency in it, because there would be a natural incentive to store your money in the biggest account so you get the most interest...
Yeah and thus making this whole principle worthless if everyone puts their MC "investment" into one exchange because then there will be no interest because there will likely be only one account.
