Of course not all coins survive. There is a future for the coins, behind which there is a really good valuable product that is useful for society
You are right about it. Not all crypto coins will survive in the long run especially to those coins without really good benefits given to the society. Only those potential coins I think will last longer like bitcoin, ethereum and bitcoincash. IMOO.
But I also don't think that every coin will survive, we all understand that in the future only the most powerful project will remain in the cryptocurrency market. I've tried to buy only coins, which have great potential in the future.
