As for coin supply ---> "moneysupply" : 21072 This amount times 2015% equals 424,600 one year from now...how are ppl coming up with billions? Please, Rainman or somebody, help me understand the math

Daily compounding makes all the difference. Average inflation rate is about 4% per day right now. So it's really not 2014% per year, it's 4% per day which is VERY different.
Yes i got the same 4% from last 2days but it was 5.5% on 26th jan
I don't know why are you receiving 4%, I'm staking from the first day of 2014% and never received less then 5.5% for 24h. If reward go to more than 24h I received proportionally to that, more than 5.5%, but never received less than 5.5%
