I think this guy or if it is a group of people are really genius and to me well I do not think we must be looking for either their existence or them are dead. I think they are heroes because their great work continues to live on and may become the world currency sometime in the near future.
These people must worship them. Actually I do not think there are as good as him. With super intelligent minds he can create virtual coins for all humanity with a Blockchain technology programmer. I think he is still alive, so please protect your own Blockchain technology.
