Bitcoin is no better than ETH!
But it has the highest acceptance in the global crypto market.
The acceptance is the main factor and the major difference between the two. Bitcoin and Ethereum are completely different from each other and anything is possible to be including in bitcoin, i still consider this as the initial stages and in the future we might see major changes and we will start using bitcoin as a currency which it was intended by Satoshi.
BTC is like digital gold ...
ETH will be like the asset of use cases in real life...
Lets see how the ETH 2.0 will change the shortcomings and i will comment on that after that.
