If I see your main concern in the above argument is the potential impact of BlackRock's entry into the Bitcoin market. reflecting concerns about the long-term consequences of BlackRock's presence in terms of the community and decentralization of Bitcoin.
Why? First, BlackRock's entry into the Bitcoin market through an ETF (Exchange-Traded Fund) can be considered as a step that could increase institutional adoption and give the digital currency greater legitimacy. In many cases, the entry of institutional players is often seen as a sign of progress and legitimacy for the asset.
Second, with respect to decentralization concerns, it is important to remember that decentralization is one of the main pillars of Bitcoin. The blockchain on which Bitcoin is based is designed to ensure security, transparency, and broad participant involvement. While BlackRock's presence may have had some influence, the structure that the Bitcoin network has built can enable wider community participation to influence the direction of development and deal with challenges that may arise.
Third, if any forks happen in the future, be it based on a BlackRock decision or some other reason, we need to view them as part of market evolution and growth. Forks do not necessarily signify conflict or failure, but are often the result of a difference of opinion and an exploration of innovation within the cryptocurrency ecosystem. In situations like these, the Bitcoin community has the opportunity to participate in the decision-making process and determine the desired direction.
So, if you look at the long-term implications of BlackRock's entry into the Bitcoin market, they are still speculative and cannot be predicted with certainty.
