I will do a contrarian view and say that 2014 will be a lean year, we started with an inauspicious beginning (some grinch dumped a big amount of btc on mtgox at the start of January 1st 2014) and we will go up maybe to $2000 and no more. However, 2015 will be a BIG year.
Wow. That is something to see it in the numbers, percentage wise. A 170% gain would be NUTS at these levels, but I think anything is possible (including going to close to 0 so don't go overboard.
One things for sure, we're likely to be picking up more participants through this year, the recent spread of media coverage has seen to that. Plus, we've got some big names in the investment space officially entering the market. Can't help thinking that more people fighting for a piece of the pie makes the pieces more valuable... although I expect the fighting to be dirtier. So there could be some serious string pulling to manipulate the price downwards for a significant part of this year. Hodl.
