No, that’s not what i meant. Let’s say there is a fork. Btc1 (as we know it) and btc2, which is more government friendly. Maybe because it introduces kyc control for every bitcoin wallet or something…
Now if BlackRock holds a huge percentage of the supply and they say „we see btc2“ as the real Bitcoin, they will just declare all the Bitcoin of their customers as btc2. And because they have so muchbof it, they can manipulate prices in a way that this btc2 rises in price against btc1. Which will lead to more ppl wanting this btc2.
That’s how i understood it. But i am just a random noob 😅
