I've heard it said before for years, but it seems when stocks go up bitcoins do and when stocks go down bitcoins do.

Stocks were rising with bitcoin prices.  When they rose bitcoins did and when they fell bitcoins did. http://presstv.com/usdetail/298479.html  That article is about how stocks are crashing bad.

I personally hate how bitcoin prices jump around like crazy.  It makes it really not useful as a currency.

I remember people kept saying there's a manipulator of bitcoin prices, and well they're synched to stock prices, which are manipulated by powerful bankers, such as the Rothschild family.

Hmm gold fell too http://dealbook.nytimes.com/2013/04/15/golds-plunge-shakes-confidence-in-a-haven/ but that's not always synched to bitcoins, whereas the stock market tends to be.
