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 have stopped comparing btc to ethereum now really. Eth has been making ranks and trying to catch up with bitcoin for a really long time now and truly, i see it pointless to compare them considering they both have their strengths and its pointless to compare anything with btc.
