Spot cryptocurrency exchange-traded funds (ETFs) are experiencing a remarkable surge in investor interest. Recent data shows substantial inflows, particularly for Bitcoin and Ethereum, signaling a growing maturity within the crypto market. 4 consecutive trading days of positive net flows for Bitcoin ETFs, exceeding $553 million on September 11th, highlight institutional and retail investors’ confidence in regulated investment vehicles. The momentum is fueled by BlackRock’s IBIT leading with $370 million inflows, followed by Fidelity’s FBTC with $130 million, and Bitwise’s BITB contributing $40.43 million. Notably, there was no net outflow for Bitcoin ETFs on that day, reflecting a broad positive sentiment.
