I would disagree with you. I think that Bitcoin is heavily under-priced right now. Bitcoin is being used as a currency by around 10 million people, and still its market cap is below $50 billion. On the other hand, the market cap of the Swiss Franc, which is being used by less than 8 million people is many times that amount (including bank deposits as well). So in my opinion, the current dip may be a temporary one, and new heights may be reached in a short time from now. Sell your coins now, and regret later.
