No any significant changes from altcoins if bitcoin dump they dump, if bitcoin pumps they pump, as OP said, in bear market altcoins falls faster and I don't think that such perspective can or would change any time soon, the dominance is what's playing the effect here
Sometimes not all altcoins drop when Bitcoin price dumps. Stable coins and some altcoins that have good news still can increase their prices. But I agree that most altcoins follow Bitcoin price trend. So, what trend happens in Bitcoin, will be very crucial as it can bring some impacts to the altcoins market. This should be our consideration whenever we want to buy more altcoins. Don't buy altcoins if Bitcoin seems to have a dump, better to wait for a good trend in the upcoming weeks.
Bitcoin is still the benchmark for some altcoins and we can see it either when it increases or decreases,
before deciding to buy at least we research and analyze first about market conditions,
it's important so that we don't make the wrong decisions
but it is undeniable that bitcoin is the benchmark to see the altcoin season arrive. when bitcoin rallies there are usually several altcoins that follow it and there are many altcoins that still haven't reacted, so bitcoin starts to range and there will be many altcoins that react to follow bitcoin's movements, from some altcoins there are those that have increased by thousands of percent, and our job is to analyze which altcoin will give good profit
