It's unclear if Satoshi has made any money off Bitcoin, ever. (He definitely did, however, spend at a minimum thousands of dollars just in hosting and mining costs, never mind the actual work of making Bitcoin.)
In any case, he couldn't make any money off it between ~2006 - Bitcoin Pizza Day 2010, because it either didn't exist or it did but bitcoins were worthless and he couldn't give them away.
The minute possibility of being a billionaire in a decade does not pay any bills in the present, any more than it does for regular startups, who need VCs or other forms of investment.
According to the NYT he makes 80K/mo from Patreon. I too am sort of confused about why Cowen brought those two up as examples - especially when I don't really see what Peterson's "moon shot" was.
