Litecoin != pump&dump Innosilicon make first scrypt ASIC on april 2014 and get about 30$ mln from the sale of them (2 months) ! Big money!
As of today we have 35.5% of all 84mln LTC, another 35% of them will be mined within the next 12 months and then inflation will be at a level such as in the case of Bitcoin now (~ 11%). Award for the block in August 2015 will be 25LTC (50LTC right now). Note that transactions using Litecoin are very fast compared to Bitcoin (4x faster).
I think we're in a good position for long-term investments in Litecoin.
