Yeah heard this shit before and also ignored it smoothly long back ago. In fact I have diverted the entire focus on collecting more BTC because that is what Satoshi might have thought the world would do. But all those curious minds are chasing and making it a business to showcase that they themselves are Satoshi. Just to gain the fame and in the name of fame money that's coming to their institutes. That is a pure myth and it will remains myth always.
Why would Mr. Satoshi want to become a public figure? The first thing that will happen is all the governing agencies will be behind him. He owns so much wealth right now, he could be just partying his ass off anywhere in the world. I think he simply doesn't want us to know that.
That was the whole point behind blockchain. Be anonymous.
