Bitcoin traded at $111,307 with a 2.05% gain in 24 hours, but analyst Charles Edwards warned that quantum computing advances may pose the greatest risk to the cryptocurrency. Edwards stated at Token 2049 that without a cryptographic upgrade within a year, Bitcoin could face its worst bear market as quantum systems approach the capability to break elliptic curve encryption. The analyst emphasized that the network requires immediate action to address this existential security threat.

Bitcoin stabilized around $109,000 following two major regulatory developments. U.S. President Donald Trump pardoned Binance founder Changpeng Zhao on October 23, 2025, ending an 11-month legal process. The European Union imposed sanctions on Russian cryptocurrency exchanges and the ruble-backed stablecoin A7A5, targeting platforms allegedly linked to sanction evasion.
