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.

Altcoin that might survive through time in the crypto industry that has the potential to is only ethereum. It is the only altcoin that i can think of because it really is strong and has what it takes to survive and stay for the future of cryptocurrencies.
