Whichever crypto currency is the easiest for speculators to manipulate into a profit, will likely be the next to shoot up in price("the path of least resistance"). I don't think BTC will be next. I would guess an alt like litecoin, dash or whatever is trading at low volume that is undervalued might have a shot. Could also be a fork coin if coinbase or another major exchange (or retailer) adds support for it.

The alternative option is, there will be a big news story that will incite a price movement. Those profits typically go untapped by traders, unless one is privy to secret, insider, trading.

For BTC, I think it'll take time for investor's to regain confidence. After a big price fall, that is a legit price correction rather than a dump, it can take awhile for people to forget and believe in something again.
