I think I threw an amounbt into it last year in around february-march time and pulled out a decent profit from it (seemed to go from 0.007 to 0.018 from what I remember), the year before when I missed it I watched it go from 0.006 to 0.022 on exchanges... It's a past history I expected to continue into spring this year but I think the whales were busy with the halving.
You are right, LTC rose quite well even way before that bitcoin bull run that started in April 2019. Someone who had made an entry at the beginning of Jan 2019 could have easily made X6 profit by July 2019.
