I read and read I can't comprehend what the man is trying to emphasize on Bitcoin. Calling it a scam is a big mistake, and other things talk about building health records on public blockchain like Ethereum, I don't think is good idea.
With Bitcoin, they can. Bitcoin is designed to transfer millions/billions of dollars between huge entities knowing that the underlying value can not be corrupted in any way. You simply can't get that with fiat.
Furthermore Bitcoin can't be compare to bank system, it very and easy means of transact and this is really helping the world.
