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.

If you talk about Altcoin, of course those who have the best technology that will grow, or at least continue to innovate. And I think Ripple is one that will survive in the future. It is possible at this time, Ripple has not represented the spirit of decentralization, but I think the developer is trying hard to make it happen. So with a business concept that has the potential to be used by many people, I think Ripple is one of the Altcoins that will survive in the future.
