Litecoin was one of the first altcoins to appear so it was heavily inspired by the ideas behind Bitcoin. In fact, it is made to be the currency that will address the major drawbacks of Bitcoin. It is 4x faster (2.5 vs 10 minutes for releasing a block) and mining is somewhat easier.
It certainly has been over the years, even though there were short term fluctuations that are inevitable for any currency. But at the end of the day, it has always been in the top 5 cryptocurrencies.
It is traded on almost all reputable exchanges, so its very easy to get a hold of it. However with the current price at $151 only did you think it has a high probability of increasing in price drastically possibly competing with bitcoin in the future as a means of storing value??
Well its currently trading at about 83$ and the charts look like shit. A drop to about 30-40$ to me seems pretty inevitable at this point. An important point to remeber is that during the last bear cycle it had dropped from about 50$ to 2$ in the space of a few days. Obviously things are not the same anymore but the whole this time its different theory has been clearly disproven given the state of the current decline in crypto prices. Its very important to respect patterns. I would also suggest you look at he historical prices of LTC on a btc price basis. You would find that even at the December top it's btc value was still lower than what it was during the 2014 bull run. Of course now the btc/ltc price ratio is significantly worse off.
