I doubt he will do that, that's too much money, now that he mentions it anyone who is in relation to him either a family (extended), friend, business partner, etc. will be interested on that. Yet i only think this is just another hype for Bitcoin for his and his company's benefit, of course, to everyone here as well.

Whilst it’s very honourable to the community & makes everybody else’s coins worth slightly more, I think there must be some relative somewhere he can pass them onto. It’s a shame really that such a successful, rich person hasn’t got any heirs. The kind of generational wealth he already has really should be continued. He’s not too old to Father a child with a younger woman, maybe he still has time.

Yes I recently saw this news on the social media Twitter (X) that Michael Saylor says, he wants to leave his Bitcoin to the civilization like Satoshi Nakamoto, the creator of Bitcoin.

I don't know if it's completely true but after seeing this news I googled it and even read an article there and found out that Michael Saylor was married to a woman named Patricia Saylor and they had five children.
This article covers everything about Michael Saylor's biography, even discussing where and how he grew up. Please note this Article;

Michael Saylor: Net Worth and Biography

Michael Saylor is a bitcoin lover and he has said so many positive things about bitcoin and MicroStrategy has also played important role in bitcoin's development due to the large amount of bitcoin the company is holding but just like other users has given their opinion about him giving his wealth to his relatives if what he said about not having children is true, so am of the opinion that even if he want to give his bitcoin to civilization and humanity he should also consider giving part of his holdings to people who are close and dear to him, however if Michael Saylor leaves his bitcoin for civilization it will further boast the confidence of many bitcoin lovers and hodlers and also make others consider doing such for further development of the most valued crypto asset which will be a good step towards the adoption process.

I am surprised that Michael Saylor dont have a child. This kind of decision not to have any heir is popular in most developed nations. In my country having children is almost compulsory for everyone. The rich who cannot have children naturally usually seek other means to have successors. But that's his decision and we have to respect it.

Satoshi left his fortune in wallets and didn't donate it to any charity. I hope this is not the path Micheal is following. It will be better for him to give the funds to people who need it. There is an increase in refugees, sicknesses and natural disaster victims that need such donations. I observe that people donate to medical courses if they fall sick, maybe this could make him donate to research and development of drugs and vaccines.    

He isn't like Satoshi who created BTC, I doubt people will learn about him and be grateful for him leaving BTC unused after years. Yes, it can add value but maybe just the 5% of the earth population who knows BTC.

If he is willing to leave all his BTC, why not just help build something for a country he loves, something that will remember him for hundreds of years like rebuilding the bridge that collapsed?  Because at some point, this is somewhat like hype again. We all know crypto is all about hype every time there is a bull market.

He really sees it as a long-term asset, and he even plans to leave it for future generations. It’s quite different from Satoshi, but it’s for everyone, right? Since there are fewer in circulation, the demand could be high, and because of that, the price could be higher.

That would be his legacy, then, and it’s a good one, in my opinion.

I think this will have to fall into the category of I will believe it when I see it. I also think he’s just talking about his personally owned Bitcoin. I don’t think he’s planning on robbing the Microstrategy holdings and burning them. So it is less of a big deal than is being made of it. We don’t even know how many BTC he has.

Well I do think he is a very nice man for him to say he will give away his Bitcoin. I do not know why someone who is a Billionaire like him does not have a wife and children.
There is some wealthy people that would not do what he is saying he is going to do. They will waste all of their wealth and buy some things they do not need. I admire a wealthy man like Michael Saylor.
