Eth has made considerabley less % against satoshi in the last few months compared to ADA and BNB.
Is it undervalued against BTC? I'm wondering whether to get some.
Undervalue or overvalued cannot be defined or high subjective to each person, so if you are making analysis based on which value then make your trading decisions as well accordingly but ETH is doing good compared to BTC and other coins in the recent days.
