it will take 35 days to mature and then you will receive 9% in pos and then there goes 35 days again before the next 9%.
I see that when I allow POS mining in my wallet, a block is find in less that 3 seconds (in average one every 2 seconds): I test this for 12 minutes (more that 320 blocks mined).
Instead POW mining takes more that 30 seconds to achieve (even 1 minutes).
Is the POS difficulty recalculation to slow in updating it?
