Based on what it has been seen among the wide array of altcoins such as development, innovation, and security issues, what altcoins might survive in the future?

In my opinion, I think that the only ones prone to survive would be good old altcoins such as Litecoin and Dogecoin, but I may be wrong.

Nevertheless, I would like to know your opinion about this as well as any altcoin that might be worth holding onto for the long term.
