Holding is always the best option. I have been holding for years, and the peak to nearly $20,000 made my holdings worth more than ever before, but it's nothing more than a profit on paper. In the same way, you have just a loss on paper. If you have been following the market for a while, and see how profitable these movements are, try to trade the market. One stash is purely for holding purposes (you don't touch these coins for a very long time), and one stash purely for trading purposes. These insanely volatile days allow you to take advantage of these money making opportunities, but you have to understand what you are doing, and have to be willing to trade against the volatility. If you're not a trader, then just keep holding and use these lower levels to accumulate (if you have free capital).
