Crypto market is unpredictable and all coins are volatile. There will come time where only strong coins with good project will remain and all other coins will fade away. That day cryptoworld will be more stabile.
I don't know if that is going to happen soon, after all more than 90% of all the cryptocurrencies fail, so in theory only the strong coins will remain however when you look at the market you see that new coins come every single day so it doesn't matter if a coin dies a new one is just around the corner trying to take its place and that is why we have more than 1500 coins and counting.
