Eh, only if I think they will make a bitcoin denominated return honestly, OR if i think what they are building is so valuable that I'd be willing to lose money in order to see it be made into a reality. But none of those companies are really in the stock market usually.

In a general sense I have no intent to invest in much of anything in traditional finance these days. There might be a very, very small set of exceptions over time, but mostly I just avoid it as a rule.
