I do not know how to comply with the norms of Sharia. I honestly say I do not understand the intricacies of religion Islam. But I invest in projects of crypto exchanges. And even if ADAB doesnt quite correspond to what was planned, then this is of course very sad ... but the main thing is to have a finished work product - a crypto exchange!
Yes you are right, from a business investment you can make up your mind.
On a moral level, their using the word "Shariah" to fool Muslim investors in to participating in the ICO makes them petty criminals and thieves
