I just discovered that in the BlackRock ETF filing there's a clause that says that in case of fork, BlackRock will be free to choose which fork they think is the real bitcoin.

Imagine this scenario: in a couple of year, the BlackRock ETF become so huge that it have a significant percentage in the whole bitcoin marketcap.

At this point, someone just release a "green" POS based bitcoin fork and BlackRock switch to support it.

What will happen is that the real bitcoin price will fall and everybody will start to support the "green" bitcoin because all the money are there.

Thoughts?
