Bitcoin's price remained steady on Friday following the Bank of Japan's announcement of a more flexible approach to monetary policy. The digital asset has been trading within a narrow range for over a month, hovering between $29,000 and $31,500. The BOJ's decision to loosen yield curve control could lead to higher interest rates, which may pose challenges for risk assets like bitcoin. The announcement caused market fluctuations in Asia and Europe, while Wall Street saw a rise after a lower-than-expected inflation reading. The BOJ's policy move could allow for a rate increase on 10-year Japanese Government bonds.
