I made this visualization by cobbling together Bitcointreasuires and Yahoo finance data.

I was curious to know more about companies that hold Bitcoin. How big are they? Are they founder-run, where a single guy has a big say in decisions (tesla/MSTR)? Still, I do not have the data. but out of the available data, I figured 'stock % owned by institutions' was a reasonable proxy. Funny enough, it doesn't work for Tesla/MSTR.

When you hover over the bubble, you will see additional details about the company. The size of the bubble is proportional to the bitcoin they hold.
