Egypt's Religious Leader Forbidden Bitcoin Trading Under Islamic Law

Trading bitcoin is prohibited by Islamic law: the religious leader of Egypt. Crypto-currencies should not be used in transactions, he reasoned, because it does not apply or is not supported as a financial instrument by the Central Bank of Egypt (CBE).

The absence of a material asset supporting the crypto currency, and anonymity in its transactions, which can lead to tax evasion, money laundering and terrorist financing, all this is of concern to Allam.
My personal opinion: Many centuries there were money laundering, and terrorism financing is not a crypto currency, it is a people's problem that they can not track, money laundering and financing of terrorism, extremism and the like, but not the problem of crypto currency.
