I would not agree that this pump has anything to do with Microstrategy, because why would 3000 BTC make any difference when the company already has 190 000 BTC? If we look back, we can see that most of the purchases made by MS did not have too much impact on the price.
On the other hand, BTC spot ETFs (US) have so far accumulated, if I'm not mistaken, more than 300 000 BTC, and regardless of the fact that they buy through the OTC, such an outflow of coins must have not a psychological, but a concrete impact on the price of BTC.
Although we were skeptical at the beginning because the price of BTC did not explode immediately after the approval of ETFs, now we see the real effect, and the question that is asked the most is how much BTC will end up in the wallets of all those companies. What there is no doubt about is that they had perfect timing regarding the approval, and now they just have to play by simple rules and there is no doubt that they will make huge money in the next 2 years.
