Blackrock is selling shares and accumulating BTC on a daily basis in order to back up client claims to the shares that are supposed to be pegged to the BTC price.  Even though Blackrock owns the coins they have fiduciary duties to their clients..and those are supposed to be legally enforceable duties, yet a lot of BIG companies are used to engaging in a variety of manipulations of markets and even getting profits over their clients in ways that are sometimes quite questionable, but legally acceptable.. and surely I would not put it past Blackrock to be continuing to manipulate clients and also manipulate bitcoin in whatever ways that they are able to do so and get away with it, including that sometimes they make money by being the BIGGEST player (bully) within various sectors that they can sometimes play off of one another when having such large stakes..
