Litecoin's selling points is that it is cheaper and faster than Bitcoin, but there a plenty of coins out there which does this too which are much better. I think it's only because litecoin is well known and has existed for a long time that it is on many trading platforms that it is getting so much attention, correct me if these assumptions are wrong.
I think longer term you should be much more bullish on Ethereum and other platforms which allow for more practical things to be built on top of them. So therefore I believe this 10x growth scenario is more likely to occur in Ethereum.
