I don't think anyone can predict the price in crypto market. When the ethereum go back to $400, I think the market will drop down -80% for the other altcoins.
All altcoin will also reduce 50-80% in the last time. That's the exact information I've read on twitter. The losses in early 2018 are too great for investorsYou're right, I also think that the Altcoins should fall in value. The ethereum should cost around 500-600 dollars.
