Alts movement are really good ways of determining the market but they aren't and shouldn't be a general criteria for making decisions.
Dominance of BTC rule the overall alt coin market. As expected while dominance of the BTC increase, alt coins crushing all together.
In this period some strong coins like BNB, ETH, LTC etc trying to resist, most of the shitcoins finding new all time lows to themselves.
By the way what was expecting also, when BTC dominance decrease alt seasons starts. As we see last 2-3 months it is not also valid analyse at current market conditions.
From 2017 to 2019 market changed so much and also dynamics. What market need is new investors who believe the system.
