This cartoon is the simplest visual representation of what and how a bubble builds and bursts.  Bubbles are nothing more than herd mentality.

If I could send a message to every single Bitcoin holder in the world if would be this.  Hold on to your Bitcoins.  Even if you "hear" the market is going on a down turn.  The secret lies in the power of the people holding Bitcoins.  By all means if you want the price of Bitcoin to plummet then go ahead and dump your holdings when the fear factor brigade shows up with pitch forks and torches.  Then they will be the ones scooping up your hard earned Bitcoins for pennies on the dollar and riding the wave back to the top.

Hold....hold....hold....and last but not least....HOLD.
