I guess people would focus more on the USD value that the BTC/ETH pair.
USD value is final outcome for investment. I don't believe in value of USDT or stable coins as those companies can be shut down or attacked by lawsuits. I don't bet my capital on stable coins
That very clear that Bitcoin has more significant growth compared to ETH as we already hit $40 this year, it doubled its previous ATH while ETH although reached a new ATH but it did not follow the trend of bitcoin which is to double its previous ATH, and now that the market seem bearish, I don't think ETH will rise to the price stated by OP, it could be a correction will come instead of significant increase of ETH.
Have a price to equalise the investment if bought ETH at its 2018 all time high is better than take loss, cut loss. I don't know how many investors patiently and bravely to hold ETH from 2018 to 2021 and make their equalizer or a small profit for their 2018 investment.
I don't believe that ETH with the price higher than $4k but it is crypto. Many DeFi tokens have too high price so why ETH won't be able to claim higher price. In the bull market, everything is possible and if you consider the 2018 market, the price more than $1200 for ETH is crazy.
