Many of these old coins are going to die this bullmarket reason being that they offer nothing to the space and no one is actually using them, those that rebrand and adapt to the present reality would survive but those that do not would die, just check the front page of coinmarketcap in 2015 and 2016 and you will understand what I am saying
Shit coins will die eventually and it is not a big surprise, re branding the shit coin will not make any changes, there will be many projects just to pump and dump and you need to identify and avoid those shit pump coins. If you look at the coin market cap the shit coins will change according to their development and new coins that have the potential will take over and what ever it may be make sure to avoid the shit coins.
