No, not every crypto coin will survive and I think some of us here had that bad experience. Where you decided to hodl the coin which you believe can go higher and then suddenly you will just find out that it has no value anymore. This is the sad reality: Cryptocurrencies are crashing. But not all will get doomed. There are still some that will surely survive.
out of 10 only 1 coins will give you good return if you hold it but balance 9 will die and even with good projects their price is very low against their ICO price. So it is always good to sell your all altcoins when ever you get profit and convert them to bitcoin which is the only coin which will give good returns if you hold for long.
