Litecoin is, like any other alternate cryptocurrency, just a scheme to steal the BTC from clueless newbies.
Just ignore it and eventully it will die out, like others before it died already.
There is something true.
And i read about the Solidcoin on the solidcoin-webpage and i mean it is the "dirty bitch" of bitcoin and the concept don´t make any sense.
I believe that the Solidcoin is the answer of the people who want to see the bitcoin dead because they are afraid to there influence and authority.
The real one is only the bitcoin self ;-)
