Never put your eggs in one basket. There are miners who have been accumulating litecoin for a few years now and they are going to be selling into any rally, as well as bagholders who did not sell fast enough from the last pump. The smart move would be to hold mostly bitcoin with only a small portion of your holding in litecoin.
There are miners who have been accumulating and bagholders for every single coin. You think people weren't accumulating Dash for a while before it went wild? Or Ripple? Any other coin that's ever had a bull run? Same goes for bagholders. I see people say this all the time, it doesn't mean Litecoin can't have a run like every other cryptocurrency that were also "being accumulated for years, and laden with bagholders".
