It has nothing to do with Litecoin. Litecoin's had almost 3 years to do something, but the coin has had nothing added to it, aside from being a bitcoin-copy.
Why does LTC have to "do something"?
It's like saying gold or silver has to "do something".
Neither BTC or LTC will ever be a mainstream currencies...
They are very slow, primitive Gen 1.0 coins...
But are VERY secure digital stores of wealth.
If you had to hide $1,000,000 from your crazy ex-wife...
There are only 2 coins where you would feel safe.
ASICs and merge mining with a slew of other scrypt coins...
Including new scrypt coins designed to merge mine LTC out-of-the-box...
Will create an LTC boom soon enough.
Just on Bitfinex LTC trades 800 BTC/day...
Or you can get 30% annual interest on LTC via swaps...
This is the beginning of serious financial infrastructure for the top coins.
Please stop with the gold and silver nonsense, that may work to get immature newbies to buy into the failing litecoin but lets talk for real here. I know many others have said it as well. IRL, Silver has it's own uses that make it valuable. Same with Gold.
Litecoin has nothing that makes it valuable, it's just a bitcoin-clone with no features, making it useless to use over Bitcoin.
Litecoin is not the Silver to anythings gold, thank you very much.
