I've got to say I'm curious to know what will happen at the end of the year when big money starts to get access. Second Market retail investors, maybe Winklevii ETF, who knows what else.
It's probably priced in already.
Unlikely, it hasn't happened yet and confirmed sources have not ensured that it will.
The Winklevii ETF won't get approved this year. (Or ever.) And the SecondMarket thing has been known for a while, no? (I read an article on it today, which seemed to state that it's basically approved, and therefore probably priced in.)
Known bullish events are priced in already.
I suspect BTC ATH happened in November 2013.
But there's still a lot of room for volatility, which will be triggered by new massive thefts, hacker attacks, government clampdowns and general mischief and fraudulent activities from various third parties in the BTC ecosystem. However, I expect this volatility to take place along a mostly bearish trendline.
