The coin or token simply needs to be a legit project, with investors interested and a solid community backing it up. If it is simply vaporware or a shitty project looking a pump and dump, then chances of it dissapearing after this bloodbath are pretty high.

The coins you mentioned have been on the market for a very long time like zcash or litecoin, and there's a reason for it, they don't have unique characteristics, people trust these coins bucause they have proven to be legit cryptos over time, that's why they'll survive this bear market. Projects who lacked trust in the cryptosphere will most likely dissapear.
