If we overlay 2018 ATH on top of the current ATH, we are looking at a potential repeat.
If ETH gets back above $1800 it might be worth shorting with a good risk/reward. If this indeed was the mid term top, we wouldn't break the ATH anytime soon.
Keep in mind though, that we may still be in a strong bullish trend. Watch the price action and decide for yourself if we get above $1800.
