do you think ETH will go down to 400$
Well, it went down to 200$. However, once the market starts recovering, hoping that the market will start another bull-run, the ethereum price will go back to it's recent ATH. Cryptocurrency market needs something big for it to gain massive attention again. Let's just keep on waiting patiently, anything is possible in crypto market.
That price of $200 had been fluctuated already on that price, and as I see with the current trend there's a huge chance for eth to bounce back for much higher price more than $400. We really need to be calm this time, because as eth coin fluctuated more, people will tend to be afraid and their emotions was the main concerns here which definitely affects the price when sudden fall of value also happened.
