I think BlackRock and Michael Saylor are planning for the long term. So that they can buy more Bitcoin and sell it at a higher price. Now it's time to see when the time comes for them.
I really can't blame you with an headline like that.
BlackRock are not the true owner of the Bitcoins they are holding
They are custodians more like managers and are paid a fee for their service.
Strategy service Now revolves around owning Bitcoin
So if they start selling, they last losing credibility and Goodwill.
If they do sell, the likelihood of them selling to take profit is quite low.
