bitcoin is techically more superior then ETH ,yes but the use cases are bigger for etheruem now!
real utility for ETH ARE BIGGER.
ETH: defi, icos, dapps, stable coins.
also the very good liquitity !!
BITCOIN ?
yes you can buy thigns with btc but so you can do with ETH.
Did you really just say icos as thats a good thing. ICOs are the poison of crypto thanks to eth it as was all made possible. Not all technology is good. These are all things that will/can be built on top of bitcoin eventually, its just not a priority right now. Besides have you ever seen bitcoin rollback :/
