BlackRock previously released a short video introducing Bitcoin. In the subtitles of the video, a statement appeared, saying that the bank "cannot guarantee that the supply of 21 million Bitcoins will not change", which caused market fluctuations and made Bitcoin supporters feel uneasy. They suspected that some market big players wanted to influence the Bitcoin protocol or implement a "hard fork" to increase the supply of Bitcoin. However, Li Zhiwei, chairman of the Hong Kong Science Park Science and Technology Network, said that some market participants speculated that BlackRock intended to increase the supply of Bitcoin, but BlackRock's statement in the video was actually just a general disclaimer. As a large Bitcoin player, increasing the supply is not good for BlackRock, because once the supply of Bitcoin increases, its Bitcoin spot ETF will also fall in price. (Hong Kong Wen Wei Po)
