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 think the market is changing a lot, and Altcoin continues to grow. At the current stage, volatility is more influential than a technological potential. And now we can say that many altcoins will survive, or all of them will not survive. But I think crypto will continue to exist, and during that time the altcoin will continue to compete.
