With bitcoin, what stops 2 large holders selling back and forth to each other pushing the price up or down. By manipulating the price before dragging the suckers in before they make there big move and make big dollars. It seems very easy for the big holders to manipulate the price with trading the same bitcoins back and forward among themselves. While small investors are just gambling not knowing these large players can make the price go up or down very quickly over any short time period by exchanging shares amongst themselves. I am just asking if this can or can't be done by you experts on this subject. CHEERS
