This research will use a qualitative approach with a library research method that uses data from various previous studies and studies still relevant to this research.

Meanwhile, in Islamic law, cryptocurrency is not issued by a legal/official financial authority, it has not been accepted by the wider community, if because it contains speculation, dharar, gambling, it is already in the abstract, only after that, because there is no physical form it is possible to have gharar and maysir elements.
