I will suggest you to prefer listening to Zakir Nyak on that topic as he is more aware of the technology as compared to the Pakistani Ullamhs (Maqsad baat ko smjhna ha Pakistani Ullamah Bohat Qbil hain koi shak nai kuch Ullmah saree nai haha)

Better to have good research on it as Bro RIBA is a very very very very sensitive topic here more sensitive than Gmbling Signature. So the proper search is important here. As far as the Intrest is involved in the trade my Strong recommendation is Future is Haram there is nothing that can save you no argument. As Ribah is directly involved. Next to it if Ribah is not involved then you can have arguments with someone but that someone is not me.

Recommendation: Be careful with this topic i know Hundreds of Future traders but i am not familiar with their research.
