What does this mean? Well.. it means that there are 34 pub keys associated with "prime nodes" which stake @ 350%/yr. Yes... that isn't a typo. Prime nodes have a minimum quantity of 125,000 XPY and, for ease of calculation and playing it conservatively, we'll assume all address have this amount.
So... according to
https://chainz.cryptoid.info/xpy/#!rich there are 51 prime address. Since there are 49 pub keys associated with higher than 5% staking rates we have to assume, and have found to be the case at least according to the richlist, 4 addresses will stake at 5% like the rest of the plebs (balances found below in edit).
125,000(.05)(4)+125,000(.1)(3)+125,000(.2)(2)+125,000(1)(10)+125,000(3.5)(34) =
25,000+37,500+50,000+1,250,000+14,875,000= 16,237,500
So that's an additional, after one year, 16 million two hundred thirty seven thousand five hundred coins just from the "Prime Nodes" in additional coins added to the blockchain. That does not take into account anything else except the "Prime Nodes".
Hyperinflation will take care of this coin on it's own.
If I'm wrong, please feel free to correct me.
EDIT: Edited due to faulty rich list. Further digging shows that there are 49 prime nodes to match the 49 pub keys. The additional 2 must have been a coding or mathematical fault. There are, however, 4 wallets with balances higher than all 49 of the prime nodes, shown below this. For the purposes of easy math, I have adjusted the 5% staking above to 4 instead of the original 2 even though the actual staking will be much, much higher on three of these wallets.

Hey guys, I just want to add my 2 cents to this scam thing.
show how the nCoinAge is computed. Which means the following, 350*CENT parameter is converted to 350/365 = 0.96% daily compounded rate, or yearly this means around 3250%. Whoever coded (copied) this coin has problems with math and 350% annual rate (if this was desired) was converted to 3250% rate
