There's a known price suppression attack going on for 6 years against Monero.

This means CEX acceptance can be used to attack a chain via naked shorting making mining uninteresting for economically motivated miners.

It can happen to Bitcoin, too.

The best thing in the long run if all CEX delist Monero. We're on the way to get there. After that, price will adjust and mining will be much harder to attack than today.

Instead of standing by waiting for Monero to be killed do your part. Start a miner and hedge a little bit of your Bitcoin holdings with Monero. 1% will do as a perfect hedge. It will benefit both Monero and Bitcoin as both are somehow codependent on each others success.
