The price will continue to bounce up and down and the reason is simply because it's such an unreliable currency to predict.
Miners sell, investors panic-sell when miners sell and the bridge just goes from there until a good piece of news comes out and the price rises, then the process happens all over again.
It could be market dictation, but it isn't always the case
Almost the same happens with anything but major currencies (euro, dollar). Look at the gold and silver price swings over a few recent years, as an example. Or at that famous oil fall and rise of 2008, when it went down from $140 to nearly $30 per barrel and then bounced back to above $100.
