I'm unclear what statement this is trying to make.

Is it meant to draw equivalence between crypto and Tesla/SpaceX? That each has roughly similar (i.e., low) value to humanity, or value as businesses?

Is it that the metric of whether a person makes others money is invalid?

The comment seems coy, possibly to avoid making any claim at all, but it must not be that because that wouldn't be very sporting.

He’s saying that it’s easy to say good things when the market’s on an upswing.
