Doge is not mostly dead because it was merge mined to litecoin. Hardly a "community" backing it if it needed litecoin miners to bail it out.
That's of course a valid argument, but my point was that it is still among the most traded coins.
Anyway, let's not dilute this thread since its all about Litecoin and one question remain unanswered: Wouldn't CT cause a negative effect to LTC's speed and blockchain/block size?
