I think this may depend on the point of view of the certain person for me the altcoin will survive no matter what as long as there is a demand of it will survive they will only die if there is not demand
I am sure that there are still a lot of altcoins will survive but i am also sure that there are many altcoins will not survive because not all altcoins have a lot of supporters and not all altcoins have a good future in the market so just invest our money in top altcoins.
