Only people in panic sell right now. Just hold your coins and you'll be fine. If you really wanted to sell your coins, then you should have done it when the price was over $450. If you don't want tiny profits, then hold your coins for the long term and you'll see that holding your coins pays off significantly more than selling at these daily peaks.
Its always good to secure some profits in short term rather then holding long, as you always have an opportunity to buy in future when price drops.
buy with rumors, sell with facts!
That technique will work well for traders. But the bitcoin is for the long term holding, so I will hold them for long term.
