In the beginning of 2025, investors have started their familiar operation—buying Bitcoin ETFs. Yesterday, during a single trading day, the market witnessed a feast of funds: more than a dozen Bitcoin tracking exchange-traded funds received a net inflow of approximately $760 million. This is the largest single-day capital inflow since the deep correction in the crypto market last October. Among them, Fidelity's FBTC performed the best, with a single institution absorbing $351 million, making it the absolute main force. This wave of buying reflects the market's continued optimism about the long-term value of Bitcoin, especially with institutional investors actively deploying at the start of the new year.
