That is right. Basically speaking, it depends on the current status of the coin. Also, in consideration of the price you bought it for. Although it may sound simple to say that one should not sell if he would not get any profit, there is no other and better way to describe it. If you bought it for a higher amount than what you are selling it for, then why even bother? One should think that every move should be geared to get a return from an investment. So, finally, just be patient and wait for the coins to rise back up.
