And with no point of reference like the US dollar, it would be hard to know how many silver coins, or what fraction of a bitcoin to charge someone.

Billionaires.

Financial freedom is better than the risk of trying to be a billionaire.

Invariably when the discussion of college degrees come up, people mention that billionaires like Bill Gates and Mark Zuckerberg never got degrees.

And the ruling class (i.e the billionaire club) have most of their wealth in stocks.

I remember helping big billionaire one day years ago...he was driving his own car, it was nice, but not fancy...something like a Buick 4 door plain Jane.

One of my college friends died of a sudden heart attack last year in his late 40's, also after 20+ years of working on Wall St (lots of pressure) and it reinforced my decision to walk away as soon as financially feasible and still have my health.Perhaps someone on BP have a story more exciting like buying bitcoin at $1 or win a sizable lottery? 

Remember there are more billionaires in the world that have no formal education it's not always what you know it's who you know and even then they don't know.

There is a lot of rent-back-securities going on and they are taking tranches on those so it's the new billionaires crack it seems.
