According to the Grand Mufti of Egypt, Bitcoin should be banned

Egypt's Grand Mufti Shawki Ibrahim Abdel-Karim Allam said in an official ruling (fatwa) on Monday that trading in Bitcoin is considered “illegal” according to Islamic traditions. He explained this by saying that the virtual currency was not recognized as legal by the Egyptian government.

“This cryptocurrency is directly used to finance terrorist organizations and this is a fact. Bitcoin can cause serious damage to the economic, social and national security of our country.” - says the resolution of the state religious body of Egypt “Dar al-Ifta”.

Egypt is not the only country that has banned Bitcoin. Asim Al-Hakim, a Saudi Arabian minister, recently banned Bitcoin, citing that the cryptocurrency is mainly used for illegal and fraudulent activities. “We all know very well that the anonymity that Bitcoin provides is often used as a means for money laundering, the sale of drugs and weapons,” he said. "Muslims should stay away from such dubious activities even though they offer easy and quick money. This is not the way of Islam."
