Despite the emergence of new social network coins such as Facebook or Telegram, i think that today's altcoins will certainly not die, on the contrary. Current altcoins such as Ethereum, Litecoin, Monero, and others will become even more priced and their price will exceed the price of new altcoins. There are currently coins of companies like KuCoin or Binance, they have their own coins, and they are valuable because they are strong companies behind them. Only such altoins die, of which they are not interested and do not have the dev team that will develop their altcoins.
