Can you provide the names of any Marjas who permit futures trading? I am currently following Ayatollah Sistani, but I believe he has not addressed cryptocurrency or futures trading in his guidance.
Ayatullah Sayed Musa Zinjani of Qum allows dealing with cryptocurrencies provided it does not break the law of the land and does not harm anyone.
Ayatullah Shaikh Bakir Airawani of Najaf and Ayatullah Shaikh Hasan Jawahiri of Najaf say that dealing with cryptocurrencies is permissible.
Wassalam.
