Is trading of digital currency such as bitcoin cryptocurrency permissible? If so, are there any conditions that must be met for it to be permissible?
Cryptocurrency dealing is a new financial issue which needs to be very clear for the Marja' of Taqleed to give a verdict on it. Many of our great Maraaje' have not yet issued a verdict on it, while few other Maraaje' have issued verdicts on it.
There are Marje's is Najaf Ashraf and Qum who say that dealing in cryptocurrency is permissible like any other trading provided that it should not contradict with the law of the land and does not harm others.
Wassalam.
