The opposite is also true; some of them have no unique features and nothing behind them in terms or development or merchant adoption. Most are just clones and get rich quick schemes. Some will survive; some wont; some will become useful and of worth; others wont. It'll be interesting to see what other alt coins merchants start accepting.
I agree with you. Most of alt-coins don't have any credibility and no chance for adoption, it's just matter of time when they die.
accepts Sexcoin haha, but also BTC, LTC, FTC, PPC and XPM. It really does depend on merchants, but we really don't need a new coin for every niche or industry possible. These coins are becoming a joke now and it takes away some of the credibility from Bitcoin and cryptocoins in general.
We have Gamecoin, Casinocoin, Betacoin, Pokercoin, Lucky7coin.
And not evern talking about animals : Elephant, Tiger , Eagle , ...
