Did you see the 500 coins offered at 112.5 and bought almost immediately?
Wasn't watching but you know, it really looks like cryptocurrencies are here to stay. It is a matter of time before we see default browser integration and Facebook picking up on it. It is a GAME CHANGING technology, currency, payment system, store of value, commodity, asset, etc.
With a float of around 12 million or so, and it being really the only game in town (no offense to the other CC's), the "valuation" at these levels is silly low. People with lots of money can probably see that quite easily and it is a risk worth taking.
In 5-10 years it will be worth ZERO or thousands of dollars, maybe more, a lot more. We may be talking Satoshi's not that far from now.
As others have said, this is to money (which has ruled the world) what the internet is to communication, transparency, sharing, etc.
Its about sharing
