Regulation of Bitcoin in 2025 is gaining popularity due to clarity and institutional integration, especially in the USA and the UK, with a stable framework like the EU's MiCA. Proposals such as a Bitcoin reserve in the USA could elevate its status, but global disparity—the ban in China versus acceptance in El Salvador—creates a fragmented landscape. Combating money laundering and preventing fraud remain priorities, while self-custody supports the decentralized ethos of Bitcoin.
