I exclude exchange accounts and 'steemit' and get an adjusted market cap of $150MM. Then I divide the remaining accounts into deciles of $15MM. I do not include 'steemit' since these are development funds and I do not include exchanges because these accounts have STEEM belonging to 100s of individual users.

Breakdown in USD

Correlated to Marine Life Weight (Mass)

I correlate each account value linearly to a weight, I use the biggest whale 'freedom' and the weight of a blue whale (300,000 lbs) to establish a basis. Then I assign a fish species roughly in line with the calculated fish mass.

It turns out by this metric the top 500 accounts are all considered whales to some degree. The next 500 accounts are dolphins and the remaining accounts are the minnows.

Correlated to Marine Life Length

I thought perhaps we would want more granularity than calling each of the top 8 deciles of steemholders whales. So I ran the numbers again using LENGTH. I again used the top account 'freedom' to have a length 90 feet which is that of a blue whale as the basis. I then assign common marine life species to each decile based on their length
