As you see, the Bitcoin is crashing and trying to break a new low until it stop.
But I won't sell any Bitcoin at this time, I believe it will rise again as it always do.

haha, you were damn right! The price of Bitcoin has raised more than 15% since your post. It is $417 right now and Lets' hope it will be $450 again very soon (I mean it will take 2-3 days not more IMO).
Patience Pays, I don't think this is the right time to sell bitcoins, this is the right time to hold for the next few months and sell it at a right time, I believe this is still right time to buy few more bitcoins, as price is not that too high, it is predicted that the price of bitcoin will cross $500 mark so if we buy at the present price still we can enjoy some good profits in the future.
