From my own view, there are lots of reasons that could amount to Bitcoin pumping well and alt-coin not moving alongside. Firstly, most times alt-coin don't pump well when BTC is pumping, they wait for BTC to gain stability at a certain price (Ranging) before they start pumping well. Another is the BItcoin ETF adoption which is not directly attributed to other tokens. But, with all this, there are still some alt-coin performing so well even more than BTC. Example, ACT coin pumped over 2000% on BingX within 24hrs. I just feel research is needed to know alt-coin that will perform well.
