I think bitcoin isn't my favorite, here is why I think ethereum is better than btc.
It takes a lot longer for bitcoin to be confirmed compared to ethereum
Bitcoin is just too volatile let just say im sending a 2 btc transaction 9.2k a bitcoin it could go up to 9.9k when it is getting confirmed.
Bitcoin has 4x higher fees than Ethereum.
More coins are being built off of Ethereum than bitcoin
these are my reasons
