RE: Is 20% sustainable?

There is around 4.2M HBD in the savings atm, that will yield 840k on a yearly level. 2022 is set to end somewhere around 600k HBD from interest.

How much is this added inflation on top of the regular 25M HIVE per year (7%) that we have now? Depends on the HIVE price. For the curent price of 0.3, it is around 0.5% on top of the 7%. Last year we were -2.7% negative, thanks to conversions.
And we can not add more inflation from HBD if we do not created it in the first place, putting pressure on the HIVE price.
