Bitcoin dominance could be fluctuating, but despite that, most altcoins no matter how low dominance is, which for some time now has not gone below 50%, will still depend on bitcoin.
It has been long altcoins grew independent of Bitcoin and that was in 2017 and perhaps early 20818 and it is hard for such to happen now.
The only factor that could result into that is if bull run is truly approaching, then we might see history repeating itself again.
But when halving will happen, will bitcoin dominate again with the history repeating before? Because now it is quite difficult to go up to 10k, is this from the effects of the global crisis so that bitcoin enthusiasts are falling?
altcoin is the same if bitcoin isn't high then other altcoins won't follow it either.
