What i meant was, a calculator where you'd type in your coin holdings, and it would show you how much you get per day in POS
This can be simply done in excel spreadsheet, taking fixed constants such us monthly staking rate and days per month.
Monthly staking rate = 5% is 1.05 as a coefficient
Days per month = 30 days (simplified average)
Following that we can calculate daily staking rate:
Daily staking rate (in words) = Monthly staking rate ^ (1 / Days per month) = Daily staking rate
Daily staking rate (in numbers)= 1.05 ^ (1 / 30) = 1.00162766
So, if you have like 1,000 HYPER you can expect = 1,000 * 1.00162766 - 1,000 = 1.62766 HYPER/per day or 50 HYPER/month.
