How would an immortal character amass a fortune? [closed]

As the title says how would someone who is immortal, and driven by collecting vast sums of money be able to exploit that to their own gain.

For context my main character was involved in experiments in the 1950s to produce even more powerful atomic weapons and power sources, when an incident with highly unstable handwavium caused her to become immortal, but not invincible she can still be injured, maimed etc but what would be fatal injuries to a normal human simply put her in a coma for several months while her body recovers. She no longer ages or gets sick, but the limits of this regeneration are untested and she has no intention of pushing them. Many labs around the world have attempted to reproduce this incident unsuccessfully, only leading only to the agonising deaths of the test subjects. So selling the ability to others is off the table. I've not yet decided whether she is open or reserved about this ability so suggestions on either side.

• Welcome to the Worldbuilding Stack Exchange! A very interesting question with potential. Please keep in mind that character-based questions are not permitted on this site. Since the question would otherwise bee too broad, please edit your question to try and make it more specific. Give me an @ after you've edited. – A Lambent Eye May 14 at 8:56
• If you should be more interested in exploring the character, the Writing Stack Exchange would be just the place for you! – A Lambent Eye May 14 at 8:59
• @A Lambent Eye, thanks for the advice I think it would be better suited there in hindsight, is it possible to transport across or should I repost there? – Cam Waite May 14 at 9:02
• Unfortunately, this isn't an on-topic question on Writing. As mentioned in worldbuilding.meta.stackexchange.com/q/7341/29, Writing SE is about techniques. If you had an idea and were struggling with how to get it across to your readers, then Writing would probably be the place to go ask about that; but if all you have is a goal for a character, and want to come up with ideas for how the character might achieve that goal, that's decidedly a "what to write" question which is specifically off topic there. Thinking of something while writing does not make it a Writing question. – a CVn May 14 at 15:00
• The same way we (probably - haven't actually tested it yet) non-immortals do. Find some line of work at which you can make more than a survival-level income. (Starting in the 1950s, electronics or computers look good.) Invest the excess in some good mutual funds. 50 years laters, you've got a modest fortune, even if you miss out on the really good startups :-) – jamesqf May 14 at 18:22

Given that inflation works against you just working at minimum wage and saving won't work. You could of course wait until you are 200 years old and then go on tours and be famous and sell books like 'how to live forever'. This will not give you billions, but definitely a couple million. Now you just work with those. Invest, invest, invest. As soon as you have 1-5 million just invest them, you will already be famous so opening a restaurant chain for example would still have your name behind it, making them popular by default without having to struggle like many entrepreneurs.

• 1) Actually, working in a reasonably remunerative field (such as software), avoiding extravagance, & investing sensibly can give you a modest fortune in 30 years or so. 2) Trump is about the worst possible example here. He has lied about his wealth since young adulthood; the $1 million loan is just one of those lies. In fact, he was given access to & then inherited his father's real estate empire, around$400 million in today's dollars. He has probably not increased his net worth much if at all, though of course we can't be sure because he's afraid to release his tax returns. – jamesqf May 14 at 18:29
• Okay, ignoring the bad example of trump, it would still work probably, would it not? – bv_Martn May 15 at 14:45
• High risk investments with little probability to explosively grow like a restaurant could be worse as an immortal since it will eventually fail taking all your money with it. Instead, low risk diversified investments that return just a bit over inflation year after year will be better for someone who will have more opportunities in their life to lose everything they have. – Nosajimiki May 15 at 17:07
• @Nosajimiki I mean, as soon as you are famous you do have a lot of money, and an unlimited source of such. Food and rent is an expense that hinders many people today from accumulating a lot of money. But I agree, there might be other approaches like spending your life studying and have a good job, while the famous route is easier I think. – bv_Martn May 16 at 5:11
• Fame will be helpful for a few years, and can kickstart a fortune, but public interest would soon wain. 20 years after people learn you are immortal, people won't still care much, and if you do a lot of investment into your own fame, you create a market bubble for yourself that will eventually pop, and lead to you losing your wealth as quickly as you made it if you're not careful. Fame does still make a difference, sure, but plenty of restaurants start up with good hooks that loose interest quickly – Nosajimiki May 16 at 16:23
