All coins that cannot define there future will all fade off and be replaced with new ones recently some dumped coins have been deleted from coin market cap.
The fact is no one can actually tell the exact names and number of the coins which will die off in the future as no one out of us has seen the future actually. However, I do believe that not so many coins will die off in the future as the market of the crypto coins is continuously increasing and more number of investors are investing their money in different sort of crypto coins as they know the worth of investing in crypto coins.
