Looks like that site owner took a lot of loss because of the extremely volatility in bitcoin value

Whether its worth it or not depends on what will be the value of bit coins when you try to sell them. Since no one can really predict that you may end up with bitcoins which are worthless.

If you expect the value of bitcoins to go up substantially from where it is now then it would probably be a better idea to just buy them directly.

Bitcoin is being considered as an intergalactic currency. Will keep you guys posted on how that goes.
