Sheikh Mustafa Umar on the Permissibility of Cryptocurrency (2018)

In this video,  Sheikh Mustafa Umar approaches the question whether cryptocurrency is ḥalāl or ḥarām with hesitancy, cautioning other scholars from making any determinations without fully understanding decentralized currency. Noting that there are a wide variety of cryptocurrencies as well as varied intentions behind their usage, Sheikh Umar concludes that the cryptocurrencies might be permissible or disliked, but at this stage in its development, it is too early to say that it is impermissible (ḥarām) in Islamic law.
