Litecoin seems to be gaining ground on being the 4th largest marketcap behind ripple. I think that litecoin could outgrow Ripple and Bitcoin cash at the end of the year with a 10 Billion dollar marketcap.
I totally agree.
I was playing on Litecoin's all summer, but as by the law the price raised after I sold my coins by 52$ price

Honestly, I didn't hear any big news about Litecoin for a long time. That was a big surprise to see this morning 92$ price really. But now I see that Litecoin depends from Bitcoin and currently they both are falling.
Litecoin is the currency in whose success I'm sure more than in anything else. I bought it for $20 and will hold till the price reaches $1k or so. I know ltc isn't really a big step forward after btc but at least people are working on it and the coin has been around and trusted for a very long time. Moreover, no big problems like hacks and forks with eth never happened with ltc, so it's quite stable. It was and always will be somewhere around btc.
