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.

In my opinion,You should buy some coins whose future is also good likeBTC,BCC,ETH, DOGE this are all some coins which i know who are working on their project and their long term plan are very good and like bitcoin even if invested for long term you can get a very good return of investment.
