Yesterday Bitcoins were at 45k usd. Really it impressed all the long term holders. Many people sold their coins also in this price. This led to decrease in demand, and once again the price fell down to 42k usd. I guess this is the hint that something big will happen soon. Definitely this year Bitcoins will cross 70k usd mark, and January gave us this hint. So it will be better if we start buying the coins at current price. We can easily make 2x profit this year as many are predicting.
