Major institutions are increasing their cryptocurrency holdings, fueling market optimism as Bitcoin leads a strong rebound. Matrixport's unrealized profits have risen to $36.3 million, with total holdings at $335 million. BlackRock has withdrawn 2,004 BTC from Coinbase, valued at $144.82 million. Analysts, including CoinDesk's Shaurya Malwa, note that Bank of Japan Governor Kazuo Ueda's dovish stance amid Iran-U.S. negotiations supports Bitcoin's rise. Liquid Capital's Yi Lihua remains bullish on the rally but cautions against trading altcoin futures.
