You realize what you said is actually more accurate describe Bitcoin? There's nearly no early Adopters in Litecoin, mining power was significant from day one, coin value has been quite stable from the start.
While you're right that this is what people said about BTC, I do think it applies to LTC much more. The LTC folk got emo-sad they couldn't print their own money anymore so made a new coin to scam...er...encourage people to adopt. Do you think they have any sort of true belief in their idea? Of course not. If LTC picked up at all they'd dump, create a new coin and say "No, we're using this one now. It's so much FASTER!"
No they foresaw a problem and created a possible solution, which is what I just proposed, LTC can easily solve the transaction spam problem that S.Dice is creating for the Bitcoin chain.
