The places to spend them at aren't going to jump out at you though, you have to dig a little bit. Btc was the first of its kind and therefore had a lot of developers for it which helped it grow in popularity (among other things) and now, instead of realizing that Scrypt-based coins just make more sense all around, you got people still clinging to Btc trying to recreate what happened from the first block to the $266/BTC mark. There's just too many alternatives now, and while people may only be mining them right now to trade for bitcoins anyway, it only takes a couple of legit services to pop up that makes people start spending their coins. This is turn hammers home the idea that the coin itself doesn't even matter, because goods will always be tied to how much they cost in fiat currency. You are just providing a means to an end for a customer and the merchant. Bitcoin got popular because it fit the criteria needed to facilitate the one thing every country in the world has in common, drugs. The criteria being that it was anonymous and the total supply impossible to manipulate because of the sliding difficulty scale.
This is really what all currencies are, a means to an end, but at least they have like faces and countries and stuff to back them up
Bitcoin doesn't have shit
