It will increase the LTC trade volume and will cause it's price to rise. There will probably be a very fast rise,similat to the previous spikes. Over time LTC will gain more traction and it will probably be traded on Bitstamp soon, because Stamp will start losing volume to BTC-E, because of the good arbitrage options between China. Because of the same base source code, it will be simple for all the service companies to adopt it's usage. The future for LTC is probably brigh. In the future, it will be easier to sell LTC then BTC, because it has less criminal history, publicly known creator and scrypt having it's advantages in hash rate growth stability and in not being made by the NSA, that isn't currently an very popular organization.
lol. That is all.
