Hey, I watched the video on the MenaPay website and around the 1 minute mark he says something that may have far reaching consequences.

"These core principles are why practising Muslims do not trust centralised authorities such as bank, which are not fully transparent over their transactions"

And a little bit before at 0:38 "each transaction also needs to be witnessed by at least two people".

That means MenaPay and MenaCash must only be traded on-chain, which disqualifies almost every crypto exchange.
