No. The question is how long it will keep its position.
What, do you expect Bitshares to conquer LTC? That's a bite that might be just a bit too big to take.
I think it's very remarkable that Litecoin actually managed to keep its (imho by no means deserved) #2 position until now.
Many tend to disagree on this, as you can probably read in many threads. I guess the community behind it is good and it has quite some adoption compared to most altcoins. I don't want to mention the security of the network either.
