Maybe try doing the math to calculate the dollar value of this "dumping" today?
There really is no need for panic. Less than $7K traded today. Heck, I'd like to see more selling, so that we can flush out folks who can't see MIKP's potential. I'd like them to leave before Mark's PRs and while MIKP is down at these prices. Get these small blocks of shares into stronger hands.
As for your question of who sold this tiny block of shares, only the seller would know. Personally, I think it is a fool's errand to go looking for who might have sold 0.3% of the O/S. It sure as heck wasn't me. I have not sold a single share since I bought them in 2021.
I am obviously NOT an investment advisor.
