Proof of Brain could become the new savings currency for Hive. Those who want the liquidity of liquid Hive but they want to get better value will buy POB. This is inspite of POB being over 100% inflationary today. On it's one year anniversary it will have 100% inflation. On the second year ann. 50% inflation. On the third, 33% inflation.
Finally on the fourth year anniversary it will have 12.5% inflation. Working out the rest with a spreadsheet on the eighth year anniversary of POB, we will have a 9% inflation rate for the following year, which is comparable to Hive but the year after that 4% for the next four years and of course only going down after that.
