seeing from the current market movements, the bullish currently that is happening to Bitcoin is not bullish like what happened in 2017-2018, this time it looks more like bullish in 2016. Altcoins that move up (such as Eth, BCH and others) looks like it only small responds to Bitcoin price movement (not yet fully influenced by the Bitcoin price). we will see the full move of Altcoins possibly next year (when the Bitcoin price was over $50k)..
It's good to see how optimistic you are for predicting 50K USD next year. But we are talking about a 25K gain for over a year only? Hard to achieve but still possible.
Altcoin is can't react because the BTC is on fast phase in terms of pumping price. ETH and other Big altcoins that barely follow BTC is just a result of some whale diverting some of there stock to undervalued altcoin.
