I have lot of altcoins but all coin price too low but why anyone know? When price come back Or All crypto are die in this year? 
It's too early for all cryptography to die. Of course altcoins fell very low, and not everyone will be able to take off then, but this does not mean that we should have less faith in cryptocurrencies. Wait, there will be growth. There are moments of rising and falling, and that's fine.
