You shouldn't demand money. It's not what anyone agreed to. He can pay you if he wants, but he probably won't.

You can demand your equity, but there's probably not much you can do to force him to give it to you. He can dilute your shares into nothing, or he could refuse to give them to you.

You've learned a few lessons the hard way: never start work without a contract; don't work for equity only, as it takes years to have any value (if it ever will have value); and accept that some clients will screw you over, and you can't always stop them, even if laws/morality are on your side.

True. I accept it. I don't think so he will pay but I feel karma is there.
