I think the price is increasing way too fast at the moment, but I'm 100% sure it will keep going up, and will do so for years. More and more people will want to buy them, but there's a max of only ~21 million of them. If you do the math, the real value of these things should be much much higer (assuming that everyone accepts it as a real currency of course, but more places accept it as a currency every day). Edit: I own 2 BTC, bought them last week at €150/each. My investment of €300 was worth €550 this week, but it's mostly a long-term investment for me so I'll keep them.
