Because I knew this thing was going to crash and stablize at no more than $100, for a very very long time.  I was here in 2011, and I knew bitcoin's potential was that it had potential.  That was about it.  Now that it has reached its potential, which is that it might have more potential, it is nothing more than just a dot com bubble and might be useful, the protocol, few hundred years down the line.  And that is in very rare and extreme cases.
