my advice is to reduce awards delegates up to 3 coins per block first year, up to two coins in the second year and to 1 coins for all other years except inflation in the first year will be 39 %, which is first of all a lot, and secondly, each delegate receives in the first year more than 300K coins with less than 50K, you get a decent amount for the year, isn't it? although this is my opinion
hmmm, your maths seem a little off...
15,000,000 1st year 15mil/101=148,514.8514851485 lisk per delegate
or you could do minutes in a day (which makes more since due to down and or uptimes)
1440 minutes in a day each node hits on average every 17 minutes so:
1440/17 = 84.70588235294118 times per day average each of the delegates hits a block.
84.70588235294118*5 = 423.5294117647059 Lisk per day, per delegate (average)
423.5294117647059*365 = 154,588.2352941176 Lisk for the first year (average).
it only goes down from there.
remember this is for a 100% uptime and perfect world delegate.
