There is no doubt that Litecoin is a worthy investment target, Litecoin is the second coin I know after bitcoin, I used to make Litecoin as daily trading on bittrex 5 years ago, and now Litecoin is growing and continues to innovate so I don't hesitate to hold it long term.
Same story here. Litecoin was the second cryptocurrency in which I made my investment. And that was sometime in Q1 2013. I got my first BTC sometime in Q4 2012, and after a few months I purchased some LTC. I remember that when I sold them for BTC, I received around 5x profits. But then I made the decision to concentrate on BTC. I still had some LTC with me, but lost the majority of them when BTC-e/Wex.nz went down (seized by the FBI). And I lost whatever remaining when Cryptopia closed down in 2019.
