Bitcoin aims for fifth straight monthly gain, fueled by pandemic-era rally and shifting views on monetary policy. The digital asset rose 2% in January amid swings from US spot Bitcoin ETF rollout. BlackRock Inc. and Fidelity Investments launched Spot Bitcoin ETFs, attracting new investors and contributing to Bitcoin’s 160% surge last year. Grayscale Bitcoin Trust conversion into an ETF and the slowdown in withdrawals from the fund boost market sentiment.
