I agree in saying that the market will have the final say so, but....LTC just seems to be lacking. BTC not only has the community, language, double-spend protection that has been created over a few years. LTC has not had any real updates that I am aware of?
On the other hand, could LTC transfers become quicker so that you could use them for smaller transactions? I've heard of this, but have not really seen what can back this up....
But of course you can make some good gains playing it as anything else.
