It seems Strategy is aiming to reach a million in its BTC holdings (1m BTC). But at some point, I believe the company is going to run out of cash. It can't keep buying BTC forever. Strategy needs to sell some BTC and use the cash to buy more BTC once market prices decline.
Between BlackRock and Strategy, I'd say the latter is more "bullish". Certainly good news for Bitcoin "hodlers". Who knows? Maybe Strategy's actions will propel Bitcoin to new ATHs. $150k is the next target. We can't predict the future, so let's hope for the best.
