here in our country btc and eth already have same wallet address with fiat so we can exchange btc or eth in our fiat money in just a second so i think there's no need to compare and look where they good at or what they worth another thing of course there's a possibility that btc might be similar in other coins in the future because we only use coins here for investing and pay some bills but they are similar as a coins here in crypto they only need support like btc as a variety of payment method
