Bitcoin removes the ability to create money at lower cost than others. And allows people to accumulate wealth that can't be debased without advanced sophisticated understanding of economics required to invest in shares.
Fiat money is entirely packaged debt. The value is diluted as more debt is created. People with large amouns of capital get debt cheaply while the average person gets it at a much higher rate. Bitcoin is a hard asset and can be used to store wealth without debasement. This will reduce demand for debt. Bitcoin creates a level playing field, it doesn't make the players equal size.
I'm not surprised that Blackrock hold Bitcoin it that the WEF talk about it, they will attach themselves to whatever people use. I'm surprised they are not into it more heavily. I don't know that there is a way to exclude them without creating something that can be abused by them.
