Chances seem to be like that because the price of ETH already touched the value of 100$ and which it is very close to 80$ market. I think people never expected this much huge downfall both in terms of BTC and ETH.
Even if it touches $80, it will bounce very quickly.
Does not seem that it can even fall below 100$ so reaching 80$ is not a question here. In almost less than 24 hours I have earned 4$ rise on 1 ETH. It is always beneficial when the market falls and then you start buying in the dip as when it starts to recover which happens quickly you can easily cover up your losses and also make some money if you stay for longer duration holding the best of the coins.
