Since I've been closely watching bitcoin's nosedive (with clenched teeth, even though I don't own enough to be sweating right now), MSTR has been on my mind. I've no doubt Michael Saylor will continue to justify his purchases and pump bitcoin, MSTR shareholders might be questioning whether it's worth holding their stock--I kind of have the feeling that at least some of them aren't familiar with how severe bitcoin's price swings can be or how much they can now affect MSTR's stock.
Here's my periodic chart dump, this one a 10-day chart:

It's Saturday in the US, so the stock market is closed for the weekend. Since 4pm yesterday when the market closed, bitcoin has dropped over $2000 in value, and it was falling all throughout the trading day as well. If bitcoin doesn't show some sort of recovery by Monday morning, my guess is that there's probably going to be a flood of sell orders for MSTR stock. Yikes.
