If your information is correct then that's a good news for Bitcoin holders because if BlackRock had purchased Bitcoin directly from the market then it could cause huge drop in the value of Bitcoin but by buying Bitcoin from Greyscale the market wasn't impacted even a little bit. I guess it's a good strategy in start but later I'm sure Black Rock will continue to purchase Bitcoin from market but in small quantities.
It is true, but in the short term it may have a negative impact, as the purchase is made from OTC, and in fact it is not a purchase, but rather an exchange of currencies from ---> BlackRock to ---> Greyscale.
Also, the absence of any interaction in the spot market and Greyscale selling more may lead to an increase in supply and thus a decrease in the price.
I was aware of this selling by Grayscale but what I did not know was BlackRock has bought it, By seeing the numbers I can say, Grayscale must have big plans for BTC, as they hold hell lot of BTC and they worth billions, maybe trillions. This 2 Billion selling is nothing in front of Grayscale's selling. But the involvement of ETFs have opened billions of money inflow into the BTC which has made it more volatile then before.
Grayscale was necessary at that time, but now there are many options and their discount fees were high. Overall, they made gains. If the ETF had not been approved, the trust would have continued, and after it was approved, they had plans for an ETF.
The real question is the seriousness of the continuation of companies like MicroStrategy, especially since it was operating as a Bitcoin proxy.
