It has nothing to be nervous about when the price drops down because that is the nature of bitcoin, no matter how high or how low it goes but it will still keep fluctuating because that is how it works, sometimes up and sometimes down.
Mostly the highly fluctuating commodities like crude oil trading will be doing similar to bitcoin trading. The very big advantage of bitcoin is, it is always moving up even among many fluctuations. Predicting about bitcoins future will be so easy for anyone in general.
Past performance is not necessarily indicative of future results or returns. This has been told and proven hundred times, and we should not forget about such things as Black swans and perfect storms. Someone with enough money in his pockets could basically bring down Bitcoin network for an arbitrary amount of time. Until the price starts going down and ultimately collapses. Things like that may not have happened yet only for the simple reason that Bitcoin is not really a big fish so far to come across someone really powerful or wealthy.
