Unfortunately it seems you didn't take into account how people would behave regarding the first minable blocks.
You have individuals (a few or many) attacking your coin by (what appears to be) using nicehash or the like.

You have the largest pool showing a pool hashrate of 3MH+, while the network registers as 1.5MH+.  It's the same attack pattern that hit electroneum.  Massive hash hit, with tons of solved blocks.. then it slows down to rougly 1.3MH to 1.4MH on the pool for a short while and another spike.

You have a small number of people scooping up all the coins so they can create a master node (or multiple master nodes?) or do a mass sell off when the coin reaches a profitable level.

Quite the unfortunate start that can cause the derailment of the coin as a desirable mining prospect.
