bitcoin per block = 50
daily block = 144
halving = every 210,000 block
halving cycle = 4years
total coin = 21mil

the amount of cycle need to empty the block will be 34 cycle.

34 cycle times 4 years = 136years. http://planetcalc.com/3718/ (input -50 in intial value x0 and 50 in intial value x1)
===================

if i want to create new coin with 10 times per block value, which is 500, it will goes like this.

coin per block = 500
daily block = 144
halving = every 2,100,000 block
halving cycle = 4years
total coin = 210mil

from my understanding, it should be 34 cycle, which is 136years. should be the same as bitcoin.

but why i get 37 cycle = 148 years?

what parameter should be taken into calculation if I want to have 136years, exactly like bitcoin cycle?
