in 2013 BTC become half just because of PANIC SELLING .
i dont think its possible now but if PANIC SELLING continue price will obviously go down.
I did not heard about it. In case it happened again, I will be very happy because that would be a great time a big opportunity for me to buy bitcoins. And I am sure many who believes in bitcoin will do the same. Panic selling is made by people who do not knew bitcoin very well.
I think all the people in this forum think that they are feeling not well. Everyone realize that selling in this day is beyond the sense. Why one should lose his investment while he has the opportunity to earn more and more money but it needs a little patience. Just wait for the price to go up and regain its old price and may be more than that and then that will be the time to sell your bitcoin or convert it into your local currency.
