What Rank Am I? Minnow or Dolphin???

My guess is your rank is dependent on your SteemPower but that's simply my assumption. I have seen multiple accounts with the same Reputation level (66) but they had different ranks. One was plankton and the other was a minnow but both had a reputation level of 66. But if you're curious then head over to busy.org and you can find your rank there.
