I believe this is your answer:

1- Bitcoin is at the moment only a stock (with a potential it may or may not become something else). And as a stock no one (not even the people at the wall street) knows when it goes up or down.

2- Since it works as a stock then it will go up and down with DOW and S&P indexes.

3- Since Bitcoin is a way to cut expenses, Walmart yesterday announced a new way to transfer money to cut customer expenses by 50%, which in turn affected all companies that transfer money (if you want some names of those companies then i would be happy to provide you with some).


People on this forum are more like hobbies. living a dream that's all (probably me too) waiting for one big news release that says all the world will drop all currency and deal with BitCoin and then the price will be come 1 million for each BitCoin.

If you want to know prices fluctuations then you need to do your research that's all and hope for some luck in doing the right decision.

However since BitCoin future is unknown yet, its price is very volatile and this became a great opportunity for many stock trader (and some hobbies) to trade with it and make some money.
Here is my 2 cents again that I learned from etrade.com training video: if people start selling then you want to be a seller, if people start buying then you want to be a buyer, DON'T BE A HERO.
