I don't think Satoshi himself would do something so stupid, especially if he continues to hold Bitcoin, he will become one of the richest people in the world in the future. I saw a very recent report where Satoshi is overtaking Bill Gates to become the 12th richest person in the world. If Bitcoin hits the $1 million milestone in the not-so-distant future, then it can be said that Satoshi will be the world's number one richest person. So if Satoshi were alive, he would never do this stupid thing because withdrawing his Bitcoin would really affect the value of his Bitcoin and that could have a negative impact.
How do you know that he is holding BTC, and not anymore able to access it? How do you know Satoshi is a man? How do you know Satoshi is a person? How do you know that Satoshi will overtake Bill Gates when actually Satoshi is 25 people and they have to share it, assuming they do not act as a conglomerate? How do you know Satoshi aims at becoming the richest person in the world? How do you know Satoshi can die if Satoshi is a project and not a single human being? How do you know that Satoshi is not 95 years of age and feels the desire to use some cash to live the best life in the last years? How do you know that withdrawing BTC from Satoshi wallets "would really affect the value of his Bitcoin"? I picked your post, but there are so many unfounded assumptions to be found in this thread. The list of questions could be 10 times as long.
Above all, if you were Satoshi, you would never touch your coins? Do I understand this correctly? You would never ever because it would be stupid?
