I also say like that, but not all altcoins are not going to survive, because altcoins on cryptocurrency are too many, so it is likely that most altcoins will not survive but there are also altcoins that have good functions that make the altcoin survive, so not all altcoin can't survive but there are some altcoins that will still survive.
We should distinguish good altcoins from fake or zero-value altcoins. People say all altcoins won't survive? That's just an outrageous lie. If we say that bad coins won't survive, yay!
