I have a rule: a negative result is also a result. We all got an excellent lesson and experience. I came to cryptocurrency in the september 2017 year. And today I I would make the same as in December 2017- sold most of the Doge, XRP and ETH, and then in 2018 year I bought only ETH for the all amount when its price was dump.
if you managed to buy Ethereum for $ 80 then you are just fabulously lucky that you did so. but I hope that you did not invest all the money in Ethereum because he has no guarantee of success. ETH 2.0 still unsuccessful
