Litecoin is following Bitcoin’s logarithmic regression curves
Litecoin on a monthly chart has definite lines long term. The resistance through the Nov 2013 $55 high and the Dec 2017 $370 high leads to a $2500 top in Dec 2021 to a $4000 top in Dec 2022. This would correspond to Bitcoin at $140,000 in Dec 2021 and $220,000 in Dec 2022.
Notice the green accumulation areas in 2014-16 and 2018-20. What follows these green accumulation areas is a rapid rise in price to the top resistance line at the end of 2013 and 2021. Selling in tranches near the resistance line from the end of 2021 to the end of 2022, whenever price approaches that line, will be prudent IMO.
