LTC currently still lives because there is a lot of (old) money invested. As soon as ppl decide either to take their profit (if bought/mined in the early days) or cut their losses (if bought at the peak) it will drop like a stone.
The reason is simple: it's old, and never evolved. It's still the old dusty LTC. The devs decided to stick with an outdated, power consuming and now ASIC friendly algo and the masses will just move away.
I don't think it will actually die, but since there is nothing new, the money will slowly be shifted to other coins. I don't think it's unrealistic to see LTC @ $5 or even lower by the end of the year.
Been around these parts awhile and constantly researching the latest and greatest, irl I am an investor/trader one rule I follow is don't trade on emotion, accept opposing views as its not about being wrong or right, I'd rather be 'wrong' and successful then 'right' and lose everything.
However I'm yet to see anything come out of this alt section that comes remotely close to being 'better' then btc/ltc, (by better I mean a greater chance of being widely adopted) and I've never really been a huge btc/ltc fan (i've often said the only thing useful that has yet come from the crypto community is the idea).
