You can really tell that this thread started at the back end of 2017. Back then, $5k for ETH in a year's time seemed quite possible. But after a difficult year so far for all of crypto, personally I'd be happy to see ETH at $1k by year end. I don't think we'll see anything quite like that Dec2017-Jan2018 rise anytime soon.
I remember tons of people said ethereum would turn back to $20 when it hit $50 in 2017 but then what happened? Ethereum reached $1450 and then those people all disappeared.
Ethereum is strong and it's gonna be the most precious coin of the world. Old ATH will be reached, trust me.
