Some people don't want to risk their Money in high risk altcoins that potentially give more rewards. They prefer to stick with the oldest, largest and most secure networks like bitcoin and litecoin.
Litecoin has always followed bitcoin so when bitcoin was at it's peak back in 2013 trading at $1200 USD, litecoin was $50 USD. When Bitcoin was trading at 20k USD, litecoin was $400 USD so one can speculate that litecoin can be trading at least 50k usd if bitcoin one day reaches 1 million dollars.
High risks at the moment if investors invest in altcoins, nope. We all saw that altcoins won't drop too much (in btc pair) even bitcoin deeply and fastly dropped more than last 24 hours. So, I believe that altcoins won't last significantly from their current price ranges, hence they will take of from current ranges later. Even when bitcoin rocketed to above $8000 or recently dropped from that range, altcoins remained very stable, and it makes a lot of sense that altcoins have all nearly been at very strong support levels. Sometimes, bitcoin and altcoins move opposite, sometimes they move in same directions, and I believe that soon they will move in same directions when bitcoin finishes its current correction, they all will move up (not only Litecoin).
at this moment altcoins prices not increased by bitcoin uptrend move, if bitcoin increase more then impact on altcoins prices is less when price of bitcoin will stable then prices will increase of altcoin but top 10 crypto altcoins are increasing with bitcoin bull move loks at eth, xrp, litecoin, bch prices. i am hoping for good in the coming days for crypto
