There's no need to panic sell... if anything this is a buying opportunity. The long term utility of Bitcoin seems to be very good, people really like it and want to use it. People love to mine bitcoins too. The price of bitcoin has plummeted before, and it came back. I wouldn't put the mortgage on it, but maybe a few hundred dollars and hold for a long time?
I find the current price very good, and I want to buy as many as possible.
The only problem is that the bank wire does not work on weekend.
Hope I can still get some cheap coins on Monday
