If bitcoin made a new All Time High record now in the crypto market, do you think Ethereum will also follow and break it's ATH last year January 2018 which is more than $1000?
We have always observed that if bitcoin rises in value, most altcoins follow as well. Even now that bitcoin has reached another ATH, altcoins are also increasing and now, market is in green celebrating the bitcoins new record.
Not every coin can reach all time high at the same time, this is natural because of many factors and market dynamics, because bitcoin is in the limelight these days due to institutional interest I will not be surprised if btc crosses 50k in a month or two all other coins will slowly follow the path and hopefully ethereum will the the quickest.
