It is true that it is not easy to follow the crypto market at the moment and also your portfolio when it went down like more than 50% within the last few weeks and possibly more than 90% since the height of the last bull market back in may of 2021. Usually in a bear market the altcoins suffer way harder from falling prices then Bitcoin itself. This has been the case in all bear market if have witnessed so far and i am following the crypto space since 2017.
I don't think that any of the coins that you have listed will die, they are just to big and established already in order to completely die. If all of them stay relevant and will also rise again to new ATH's when the next bear market comes, i don't know. Some of them will some of them will probably not.
