Turkish government decided that cryptocurrencies Including Bitcoin and Ethereum are not possible for muslims because the government can not to control them. This subject was called on a meeting of the state Directorate of Religious Affairs (Diyanet) on November, 24.
Buying and selling virtual currencies is not compatible with religion at this time because of the fact that their valuation is open to speculation. They can be easily used in illegal activities like money laundering, and they are not under the state’s audit and surveillance.
From the statement of Diyanet
Previously Turkey was a target of Bitcoin startups after the country banned PayPal. Also BTCTurk failed to find a banking partner after local institutions terminated its accounts without warning.
Morocco banned cryptocurrency too. But not all muslim countries consider with this statement. For example, United Arab Emirates are using cryptocurrencies transactions with India, Iran welcomes bitcoin. Others, including Nigeria, have not ban cryptocurrencies but are wary to them.
