I think the price will go up with increasing difficulty of mining it (i.e. lower amount of additional coins added to the pool), as well as the increased attention it receives from the media (i.e more people buying it). It is however a very volatile currency. Especially with 'casual buyers' panic selling. You'll see lots of ups and downs. Best strategy IMO is to get yourself informed about trading strategies and apply them accordingly. There's a lot of profit to be made if you know when to sell and when to buy. Determining those timepoints is the difficult part, however    But that's generally the case with trading.
