Since block reward random, a little bit hard to calculate, but maybe this raw math can help
max supply = 500.000.000
total POW = 200.000
average coins per block = 2500
let assume block time 60 seconds, i can't find how much block time,
so in a day, there will be 1440 block mined = 3.600.000
in a month = 108 Mil
Please note, this is just raw math, there is much factor which affect, like nethash rate, miner lucky, etc
so the coins mined everyday maybe more or maybe less.
EDIT : with current nethash around 30 GHz - 50 GHz, i doubt we can mining much like that, maybe around 500k - 1 Mil coins per day
well, dude
do you read carefully ?
that's just a raw math, and the reality now is only around 500k - 1 Mill coins mined per day, so that around 15 Mill - 30 Mill coin per month
and now only around 12 mill in circulation, because 20 mil coin locked and no one can access it.
