I completely agree with you. The target users for Bitcoin and Ethereum are entirely different as per their objectives intially. Bitcoin is targeted to replace the fiat currency whereas Ethereum wants to be fuel for cloud computing and Decentralised internet. After some time all of us believed that Ethereum also can be used more efficiently than Bitcoin. But Ethereum failed to fulfil the charectestics of money and Ethereum will never replace fiat portion because it is not designed to meant for money.
