People think the blockchain is a miraculous piece of technology, but it really isn't, and when it comes to financial institutions adopting blockchain technology, it definitely won't be immutable.
Financial institutions thrive on reversing and correcting information in their massive database, not sure why people think they will ever make use of a truly immutable ledger. It goes against everything they stand for and their way of doing business. They make the rules, bend the rules, remove rules when they start to work against them, and spit on people like they are nothing but potential income for them. It's their game and without Bitcoin we would be subject to these financial institutions for many more years.
People should grow a thicker skin and stop hoping for the blockchain to save the world. It won't.
