You don't have to, but it's kinda dumb not to. You can cram it all into a wooden chest and bury it in your backyard if you want, but while its down there its slowly losing value.

Instead you can set it up to make more money for you, without you having to do anything. Money, in sufficient quantities, can become self-replicating unless you do dumb shit with it and waste it. You just hire someone who knows how to make that happen, some financial manager of some sort, and they take care of it. You can even set it up so they just budget out an allowance of your own money for you, so you know how much you can spend every month or whatever. If you want.

This way you don't have to worry about anything, you just know you have such-and-such amount every month to play with, just like most people. It's just a lot more than most people get.

A fiduciary (not an accountant) will know what to do. Contact a fiduciary

I'd buy a nice house somewhere a bit wild and in the middle of nowhere on the south coast of either England or Wales, something old with character and a big garden with a good pub nearby. I'd also buy a classic wooden sailing yacht and put enough funds aside to maintain her as well as kitting her out for serious passage-making. When I'd done that I'd figure out how much money I need to make work optional for the rest of my life and how much would keep my family comfortable in an emergency, as well as a small 'shit hits the fan' fund kept in something you don't need electricity to access like gold just in case. I'd then donate the rest to charity, the bulk to enviromentalist lobby groups and charities directly helping people (the RNLI comes to mind for example) but also to a few niche causes like keeping the ailing pirate radio ship Ross Revenge afloat and starting a breeding programme to save the highly endangered otterhound. I'd also like to have a few documentaries made, and I'd drop a few content creators I like some donations too.

Honestly all I really want to do is go sailing and not have to deal with the rat race, I don't want to live an oligarch's lifestyle and I definitely don't want the sort of attention and arseache that money would bring you. That money would be far more effectively used for good in the hands of others so I'd end up donating the majority of it, I suspect on the order of 80% of it at least.

Invest in my people (friends and family), especially the ones I care about. Not exactly a win win but it's basically a wash in the worst case and a super win in the best case.

If they succeed in their endeavours, I get partial ownership in it or it can be a loan (whatever they prefer) and if they run away with the money, it's a cheap price to pay for setting up someone I cared about with a better life and finding out they were not trustworthy.

Also, if spread around enough, there will be enough people who will be thankful to you for improving their lives that they'll be there for you for a lifetime.

This is all after you do the usual investments with some amount and also keep enough aside from any ideas you want to try to bring to fruition (you'll want to do something at least after all)

Buy lots of weed. Buy a place to make a workshop. Buy lots of machines. Teach teenagers (and adults, if they want) woodworking, metalworking, and robotics. Make some money on the side from random comissions. Maybe bild myself a wooden house.

A lot of wealthy individuals "park" their money in things like real estate and art. For the art, they safely pack it away in warehouses. There's a whole industry that'll do it for you. A lot of them dont even see the art. It's just a wealth parking vehicle.

Another avenue is starting one or more non-profits and philanthropy organizations for the money.

And another is a living trust, to avoid probate when you die, to maximize the inheritance for your surviving beneficiaries.

Multiple banks, only storing what is federally insured by the FDIC in as high yield interest rate savings accounts as I can get.

Invest a decent chunk, find somewhere I can be away from things, set my dad up somewhere nice he can get the medical help he needs without worry.

After that, work on funding pro-womens rights and LGBT+ causes and platforms. Do what I can to help others in a position like mine, where there isn't really a "safe" place around to let the mask drop away.

100m $ !? Other than buying all things I and my family need, I may invest a in real estate that I could rent, and put the rest in the bank.

If you have any decency, get rid of most of it, preferably to charities or political causes.

That sort of wealth in the hands of a single person is obscene, and spending it on luxury when there are people starving and homeless in the world is the height of immorality.

I don't know, I'd probably just give 50 millions to charity and hire a professional to counsel me on what to do with the rest
