I cut that topic in my last post.
Things are just worth the money that others would pay for it. Money is worth something, because it is a widely accepted trade ressource that can be traded in for other stuff. If people wouldnt accept it as payment, it would just be some scrap metal and paper.
Bitcoins and litecoins also are a widely accepted trade ressource. They are just some digital bits, but people are willed to trade them for other goods (both legal and illegal, same as real money). So the more people want to have bitcoins for purchasing stuff, the more they are worth (as they are limited).
All the other [insert-something-here]coins arent accepted payments, and chance are pretty bad that theyll ever be, as they are just clones of bitcoins (imagine - ignoring all the laws and stuff - youre printing your own paper money, and trying to make it a common currency. Youll fail. Why would anyone want to replace the current paper money, or complicate things by using two kinds of paper money?). So the only guys interested in buying them are people who want to invest some money in the hope the value will rise some time. But it wont rise, except there are more people investing into it. Thats a common economic phenomenon (no idea what its called like in english, maybe something like "asset bubble"), speculations pushing the price of something above its actual worth. Thats the single peak I mentioned before, that marks the death of all those coins.
