And banks will definitely be replaced by Bitcoin, that's for sure.
Will Bitcoin replace banks just because it is more profitable than banks?
No offense, but if you think bitcoin will replace banks just because of that then you don't seem to understand the role and mission of banks in the world economy. Banks is not just an institution that deposits money and pays interest, or just a system that is used only to make payments. They are a very important financial institution because they provide most of the financial related services to help people, businesses and also help sustain our economy.
Can Bitcoin provide financial loans to businesses, provide insurance services, and more importantly, can it act on behalf of banks to regulate the economy through monetary policies?
There is no way bitcoin will replace the position of banks. And why do some people here still insist that bitcoin will take place banks position in the future when even Satoshi himself does not see bitcoin like that, but he invented bitcoin so we can gain financial freedom without the banks and government’s intervention. We can be our own bank with bitcoin but it does not mean that bitcoin will definitely replace the banks from its existence.
Generally, people will still favor banks over bitcoin. It can co-exist with banks but it can never stop the banks from its operations.
