What is the ruling on buying and selling bitcoin?
Question

Recently many companies have begun to deal in and recognise digital currencies, including bitcoin and others. I want to know the ruling on investing in bitcoin, but I am hesitant because I do not know the Islamic ruling on this matter. What is the Islamic ruling on that?
Praise be to Allah.The source of this currency is still unknown, and it is surrounded by a great deal of mystery, problems, fears and dangers.
Hence we do not advise you to invest in it until its true nature becomes apparent and it is known who is behind it.
Even now, the facts of the matter are not clear to us, so we are unable to issue a fatwa concerning it.
And Allah knows best.
