Price stability for a few days makes me a little less worried about the possible price action. However, don't you think rewards are maybe too high, as presumable coin holders want to extract fast profits from thier masternodes?
Rewards are not too high. From block 72001, block rewards will start reducing, from 2 P59 coins to 0.59 coins at block 177212 and further. Block rewards will eventually become lower, which will reduce supply.
Yes rewards will become lower with time, but you could accelerate it by blockchain update, so less coin will appear on exchange and price goes higher.
