The ruling of the Sharia on the most famous cryptocurrencies

The world has witnessed a wide spread of cryptocurrencies in recent years, led by Bitcoin and Ethereum, Ripple (XRP), and others, which has driven many investors and traders in the Arab world to seek the legal ruling on dealing with these currencies: are they permissible or forbidden?

And because the topic is relatively new, the opinions of scholars and legal bodies have varied, with some permitting trading under certain conditions and others rejecting it due to the risks and uncertainties surrounding it.
