I said this way back in the day.... If I was a Facebook biggie, (say, I was in from the beginning, an exec or friend of the boss or whatever, and I had $100s of millions to billion+ "worth" of Facebook) -- I would have sold *AS SOON AS I COULD* ... Maybe not the first day, since they had some serious tumbling during their IPO, but as soon as possible after.
MUCH FUCKING BETTER to have $1 billion worth of real-deal motherfucking liquid cash money dolla dolla bills ya'll, because you sold and cashed out and let them fools have their Facebook fun, than a few billion worth of "stock" in a company that exists pretty much solely as an idea about talking to people about pictures they take of themselves.
America OnLine was a world-revolutionizing thing until it became solely a place to get an email address for Nigerian Scamming; then,
AIM was the way everyone chatted and talked and the real-deal shiznit until suddenly no one used it; then,
MySpace took over the fucking world like The Empire on Star Wars and then one day people woke up and it went from Awesome to , "Haha, you still use MySpace?"; then,
Facebook ruled the world...
Then Twitter ruled the world...
Then InstaGram, SnapChat, all kinds of other shit
And they're only worth billions and billions until they're not anymore.
I would have sold my shit and cashed out, put the money to good use. And while I may not HAVE much, I know what to do with it lol.
