My two cents: What we've seen today is a mix of a lot of attention, probably some serious DDoS-ing and alot of panic buying and selling. There's no reason BTC won't just bounce back up like after all the similar instances. It is obviously undervalued in terms of the value it needs to have for its obvious benefits in exchange, cross border, cross countries and cheaply.
But seeing the breakdown of many major BTC sites like Gox, bitcoinity and clarkmoody as well as slowness at bitcointalk we definitely need an order of magnitude better servers if not ten orders as well as serious anti-DDoS capabilities. And what about serious attacks, like coordinated hacking attacks at all bigger accounts and sites? Security needs to be upped manyfold.
Because of this lack of infrastructure, BTC still cannot be valued at $1 million. We won't be there until we have NYSE traffic handling capabilities.
