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.

I agreed to what you have said but there are still some who will end up extinct and will vanish from existence once there are no people who are patronizing them.
