1) litecoin has been around for 2.5 years, and doesnt seem to dethrone bitcoin
2) the next bitcoin update will reduce fee's which will keep reducing if people demand it. so an altcoin wont compete here
3) bitcoin has anonymity until you want to exchange it for FIAT. same will happen with any altcoin that wants some actual purpose
4) premine helps no one but that first miner. easiest way to lose faith in an alt is to premine it.
5) if an alt wants to succeed. their needs to be a true purpose. not some story about why it was invented EG Takeicoin: because george takei endorses it. Mezacoin: not some story that one native indian pretends his whole community use it (when the dont)

actual retain usage.

so lets take an example.
imagine facebook made an altcoin and all facebook credits were the coins. or microsoft got rid of microsoft point and instead sold microsoft coins. or even the local credit union in your town that instead of holding fiat. they converted peoples deposits into an altcoin pegged at a 1:1 against the fiat.

if the only purpose is to mine coin to exchange. that coin will eventually drop to 1 satoshi price value and then be dropped off the exchange listings.

so to all of you altcoin creators. stop making sun,moon, star coins where your just thinking up random names simply to make a new coin you pre-mined and the only purpose is to swap it for btc.

use your brains and actually try making the coin have a proper real world purpose for once.
