I don't know if you are aware, but altcoins are no longer affected by movements of bitcoin. Therefore I find it unnecessary to discuss this issue these days Maybe that's because we still can't see enough hard action from bitcoin but still my expectation is that in the coming months we will see a mini alt season and the bitcoin will start the bull run after it.
I agree with you that altcoins are too dependent on BTC in the market. What matters is when the altcoins return to the market. Perhaps we need new things, projects with good ideas and quality will pave the way for altcoins to come back again.
