Hi there,
I'm relatively new to Bitcoins, I began trading on bitcoin.de about a week ago and registered at Mt. Gox recently. I believe that the Bitcoin price will rise to an even much higher level than it is now. I don't think that the price will crash dramatically in the near future: it couldn't be regulated or forbidden by nations. The only real risks I see are possible technical problem I read about, i.e. the rapidly growing blockchain and transaction jam. I'm sure it is possible to find solutions for these problems.. In the long-run, the concept just works.
