Bitcoin, more than anything, needs Litecoin to rally. It would officially cement the sound money narrative and kill any altcoin that does not abide by those principles.
All I usually post in regards to $LTC is adoption stats/data, showing despite price, it's achieving network usage that surpasses most, inc BTC.
Time to speculate. If Litecoin price is to reflect adoption, the chart I use for targets/resistances is LTC.D. First horizontal tapped.
