Cash rich businesses are the best match for a bitcoin treasury. It was always a bit of a novelty and statement that Tesla was adding Bitcoin. The way Elon has been complaining about the US debt I wouldn't be surprised if he adds some back at some point but the stock is struggling despite the fact they are doing wild and amazing things. That's the thing about stocks that are priced for perfection (same will happen with Nvidia at some point). When you pay up that much you are buying all the imputed growth and unless they blow the numbers out of the water you probably aren't going to see much of a return.
