The levels are based on 'VESTS' which are the internal representation of our stake. A million of those is minnow and it goes up 10x for each level. You can see it on Hivebuzz.
So you are a third of the way to minnow, which equates to about 538 HP. That goes up based on the inflation rate. I hope that makes it clear.
Thank you! Not everything clear yet, but I will research more, :) thank you for pointing right direction!
