I think that when Ethereum dropped to 140 USD ish last month, people was shocked like me, because it's a sign of weakness of this coin, despite the fact that it's the first and biggest altcoin
etc.
Personnaly I think ETH will recover, but not moon like the last year, and maybe we will see Ripple or BCH second on CMC.
and you see how other promising coins fell. Each project has its own nuances in its development. I will not say that ethereum is already a finished product, but nevertheless it is updated and improved. Its price will be ten times more than it is today.
