No, ethereum is not a chepaer/faster bank. Ethereum is a platform to run decentralized applications. Decentralization is the big deal here.
This is the answer I am searching for since I am not agree anymore to treat eth like money. Because sending money on the internet is supposed to be free and fast. And ethereum is bigger than money.
Now I got my answer, eth is platform to run dapps, not a payment gateway. Thanks man
