Litecoin needs new development and more marketing to become successful. Even still, it might survive because it is one of the oldest alt coins out there and Bitcoin's brother. Maybe a Litecoin 2.0 would be a great idea. 

Nope it's still number 2 by convention after all aka market capital.

What is there to develop in Litecoin itself though? The main part of it was that it was supposed to have more frequent block times and uses Scrypt, but that's just so plain now. A Litecoin 2.0 would probably not even be looked at as well. The only thing that could save it would be large Litecoin ecosystem developments, but still...

I dont really see Litecoin as bitcoin competition, i think they're too similar (from what little i have learned over the past few weeks)
but i dont see no reason why the two cannot healthily coincide together.

In fact, I've been contemplating making a purchase of some litecoin =)

The Silver to Bitcoins Gold?

litecoin rise up because price bitcoin is down,
not 100 % up dude, just rise %1-20% now the price is 0.009 btc

from first LTC always worth until now, i guess not dead

Well the confirmation time is shorter which is a plus

I think litecoin more faster than bitcoin if about confirmation,
Sometimes I took 15 minutes or more to get 1 confirmation when sent bitcoin

The block time of Ethereum is 12 seconds, it need 500 blocks to confirm a transaction in poloniex. so the total time is 6,000 seconds. For litecoin, the block time is 2.5 minutes, it needs at least 24 blocks to properly confirm a transaction.

Bitcoin or Litecoin have advantages or disadvantages of each. because bitcoin use sha-256 and Litecoin use scrypt. and I prefer Litecoin. Bright future for Litecoin.
