Hey, I watched the video on the MenaPay website and around the 1 minute mark he says something that may have far reaching consequences.
https://www.youtube.com/watch?v=575ZRW3n5PU&feature=youtu.be&t=54"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.
