We should completely avoid buying or selling at this current situation. Market is really unbalanced and there are a lot of fluctuations we can witness. All these are made by the big sharks in order to get profits. But sad to know that there are some panic sellers who falling in this trap and selling their coins. Nevertheless they are setting example for others. Bitcoins are for long term investment only, so think again before selling. Only sell these precious Bitcoins when you need money in real emergencies.
