the only coins that are worthwhile long-term so far (imo) are bitcoins, litecoins, and namecoins. there's way too many altcoins now. it's getting pretty ridiculous with these jokecoins like bbqcoin and yac (yet another coin). people nowadays just see new coins as an opportunity to make a quick buck. i don't think anyone actually "believed" in chinacoins. hopefully we'll see some new coins in the future with actual merit.
