ETH could go back to $250/220 before it can go up again.
In the $280 area is not much support (for now) compared to the last time a few days ago.
Luckily I stopped my last trade manually and sold already.
I go not in again in the $280 because it seems to unsecure for now.
Please see this idea. He could be right:
Expecting now $280-270 as lowest because support is more tough than I expected before.
