Actually we already experienced it no need to mention but yes sad to say it is now in the dump situation where all of us are already lose pur profit 
There is another side of coin as well. We have to be sharp minded when things are going against our plans. Once the prices are going down, and if you have luckily invested in Bitcoins already, you got best chance to buy more. You need to be profit oriented and for that you must be vigilant and wise enough to see your hidden profits. Rest, leave everything on the luck and skill.
