As far as I can tell the op has some beef with litecoins. He wants them to developed or change it or whatever. Bit those other coins he mentions with better "features" still don't have the one feature which matters when determining value: what someone is willing to pay for it. Ltc has an established community, stable volume on exchanges, beyond bitcoin, its the only crypto you can actually use to buy something other than crypto. Its obviously far from dead.
