none of them is going to up. I think cryptocurrency bubble will burst, wait and see.
You are probably right in this one, one day this will stop, and rush for the exit will be epic. I hope this won't create big damage, but certainly many will lose their investments. BTC will correct i'm sure but ETH doesn't fills me with trust.
I do not think this bubble will burst quite yet. It's still too young.
Nobody know exact date, but something is preparing.
