I think that Blackrock is a serious company owned by a serious person with a serious mindset of wealth accumulation. My fear however is in regards to what happens when a huge Bitcoin investor like Blackrock decides to sell off all its crypto currency holdings?
What will happen to the market when these large institutional holders decide to liquidate their assets or diversify their portfolio?

Companies with large pockets and even individuals that have same large pockets can buy via Bitcoin ETF and that's why it was launched earlier this year preceding the halving event that occured. Bitcoin investment may soon become so expensive that common investors may find it hard to invest unless they follow a strict investment plan like DCA strategy to achieve their goals and aim.
