BDCB reminds the public that cryptocurrency is not legal tender in Brunei Darussalam and is not regulated by BDCB. It urges extreme caution because of unknown-jurisdiction platform, fraud, and cybersecurity risks, and published a specific reminder on crypto, mining, and scams. This does not support claims of free adoption, exchange availability, or provider authorisation. Regulated financial activities may require a licence; verify BDCB registers and rules before acting.
