although whenever Microstrategy bought btc, price went down lol ... but honestly 4$ billion worth of crypto in one organizations hand isn't good in my personall opinion
That is about 130,000 BTC? I think that there are whales or cooperating groups who own even more than that. It can't be proven if they are careful and keep the wallets disconnected from each other. Big players could have been accumulating for a long time at low prices when they started a decade ago.
