The next 8 hours should be interesting. I suspect a drop to the lower 3K
Then the more reason to buy. If it goes back to 6k you double your money.
There is risk in buying but take that risk as grown man's wisdom.
As soon as the banks open people will start wiring money to exchanges. The best/lowest prices will probably be at the weekend. Get your discounted black Friday/Sunday Bitcoins while you can.
