I supplemented this table with a plot and suggest exponential decay.
This is what Brave suggested with 5% monthly reduction.
You can see that decline is massive in earlier month, which I do not think will be good for the community.
What I suggest is an exponential decay of the rewards. I also believe that a plot is worth a thousand words, so I will let you decide on the exponent.
Yellow has an exponent of 0.02, which looks much less aggressive than 5% monthly reduction.
Hope this helps @clayboyn and @bravetofu
Thanks AZ. Very helpful to put this into a clear visual.
Btw @clayboyn had already suggested it a while back, so I think credit for the idea should go to him :)
