Because Bitcoin is the king, so it does not need to be explained. About Litecoin, some say regularly here that it is China's baby, so I guess it is the reason. There isn't any other altcoin worth the try and that proved to be reliable over the years.
It's because LTC is the oldest and heavily supported and adopted.
It's has nothing to do with skin color
NOOBS you would know that if you were here years ago.
Tenebrix never took off.. LITECOIN DID !
How many of you morons know what a P2Pool is ?
Do your homework then post your little kidiot Investard noob theories..
Funny thing is back in the day there was 1,000 topics a day on LTC and it was popular.
Guess what noobs ?
When your Ethereum or what ever is long gone people will wonder about that too.
Like PrimeCoin and it's Cryptsy market.
All these topics and comments just remind me off how big of a noob you all are.
