Hate to say it, but I agree with @thehuemanatee. If you are smart enough to create a successful crypto currency, then you’d not be dumb enough to have a system only you know how to access...there would be a group of officers in the said company. India is a place where you can purchase a death certificate...especially if you have a nasty disease like Crohns...it makes it somewhat believable. Too many red flags with this one. If he truly was the only one who had access, then he certainly had access to all the accounts.
