Tesla (TSLA) announces it sold most of its Bitcoin

I'm confused by the math in this article. It claims that Tesla spent 1.5 billion (I'm ignoring the "increase to 2 billion" for now), then sold 75% for 936 million, and is somehow "still likely up on its $1.5 billion investment"

I'm not a math guy, so forgive me, but if 3/4 or .75 = 936 million, then wouldn't .25 = 312million, meaning 100% would be 1.248 billion, or a roughly 250 million dollar loss?

I'm not even sure why I care enough to think about it this much.

Buy high, sell low?
