Well, you can't just criticize this person for saying Satoshi is a classified material. I mean this guy right in front of us is known to be a computer scientist. So, he probably is a believable subject when It comes to the field of computer science.
Yes it is, he might know something that we don't know but for credibility I don't trust him as of now coz honestly I just knew his name today and after some basic search about him, I found that he is computer scientist but still I don't believe in him, and I bet either you would believe in less popular computer scientist. He did not even mention anything of what abouts, anything specific or pointed to bitcoin in the entire video.
For all the times that we are talking about Satoshi, aren't we tired of digging the truth bout him? lol. I'd rather assume that he is dead than watching this guy spitting some "conspiracy".
Now, his response to the question is the safest answer than those people who claimed to be Satoshi or knew Satoshi personally. His answer by far is more believable than the other theories.
Nevertheless, nobody knows Satoshi and that's what I believe.
I believe that no one really knows who Satoshi is, even the most classified agencies in the world, they could not find him in any way coz if there's one hole that will lead to Satoshi, crypto enthusiasts will be the one that will find it.
