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.
I don't care about the comparison since i am willing to use Bitcoin as investment material,so in any reason i will still Buy and Hold(if having opportunity to sell in high value then be it) even years may pass.
because for me there is no real and perfect crypto than Bitcoin(lol this is my opinion please respect it)
Anyway even we can buy things in Ethereum but still limited than what bitcoin can.
