You'd need to calculate the compound interest

If choosing the second option guarantees I would still be alive to receive that dollar, then hell yeah.

I'd think living for five million years would be a curse more than anything else
- Yeah but... Fuck it; I've got nothing better to do.
- It’s not a commitment on our side though, we can stop living when we want to between now and 5 million years later. Imagine loving it and reaching 4999999 years though…
You will die, come back to receive your dollar, then immediately did again.
I'm sorry.
- Oops I did it again.
So you'll receive the dollar and then just die? That's almost like not getting the dollar at all. Think about that
- A wise man once said "money can't buy happiness, but i'd rather die holding one dollar than die holding zero dollars"
Ah fuck, I wanted to say that. 😅

All the compound interest calculators on websites refuse to go over 100 years so I guess I'll just take the 5 mil 😭

The interest is zero. That's the joke
- If there is enough deflation, that dollar could actually be worth billions in today's dollars!
- That can't be right, no bank could be so evil
- Oh but the fees are non-zero!
You can calculate it manually as Future Value = Present Value * ( 1 + Interest in integer form )number of terms
So for example a $1 at 6% APR for 5,000,000 years would be
F = $1 * ( 1 + 0.06 )^5,000,000
F = $12,615,609 if I'm not too tired to think straight rn
I think technically that does outperform inflation so you will have slightly more purchasing power than $1 today.
- I knew someone would pull out their textbook and do the math if I played dumb. Weaponized incompetence wins again!
Sucks

If, in 5 million years, we are still using dollars, then we deserve to be turned into whatever compound Zeeblorp is interested in schmearing on his bagel.

We’ll be using the Eurodollar by 2077. I don’t know what the exchange rate is from dollars to eddies.
- Just get a chip from a hotel room, and you'll have all the eddies you'l ever need, I promise
At last they still have bagels!
- If there's no humus to be had, then humanity is doomed anyway.
It will be Galactic dollar, no US dollar.

Unethical number game suggests that if you invest 5mil into property now, you'd soon afford to double that, then quadruple that, then... By the end of said term, every square meter of Earth would hold some kind of an empty apartment complex.

No matter how you invest them, they won't be worth a single dollar in 5 million years so rather take the second option

5 million years. It might be nice to live that long

If the wish granter were powerful and genuine in how it was implemented it might also guarantee continuation of the human race for 5 million years.
- And yet after five million years, long after humanity as a whole has fallen, you live. Standing in a grassy hill which once was New York City, you look upon the horizon.
  Meanwhile somewhere within conrecete cave, deep under millions of years worth of dirt, some ancient server stirred to life, powered by some unknown magic. With it's last spark of energy it processed operation kept within buffer, reassigning value of one between two different datasets.
  As soon as it happened, you felt relief and gave out last labored breath of life, letting it finally go...as you earned the dollar you wished for.
so many ways that wish would go wrong.
ain't worth the risk mate
- I didn't ask for six million I ain't greedy

"5 million in a year"

That year is 2143. And the US dollar has been defunct since 2028 (probably). Enjoy

After 5 million years, a pristine dollar bill will be a priceless historical artifact. I’ll take that.

If money doesn't exist then what would you even sell it for maaaan

I'd pick the dollar in 5 million years. At first my choice may seem absurd to financially illiterate people, but it's called "passive income", which is the key to getting rich beyond your wildest dreams.

How about 5 Billion now?

After taxes, you'd only have like $4.9 billion. That's how they get you. You'd be better off taking the dollar in 5 million years and letting it grow.
- You do know that interest earned is also taxed right? Letting it grow means you pay every year of how much it grew.
Money doesn't bring happiness
- But it can buy a jet ski. Ever see a sad person on a jet ski?
  (Stolen from... Tosh? I think?)
- I don't want to be happy. I want a house, clothes, and food. And a significant coffee and Scotch budget.
- Money pls 🥺👉👈

5 million years, because bread tastes better than key

It says nothing about interest, just that you'd get a dollar. There would be 5 million years of inflation that devalues that dollar and to top it all off we'd all be dead in 5 million years for roughly around 5 million years lol

Would rather get a dollar in 5 million years. I was never book smart, instead I'm money smart. It makes me more intelligent.

I'm guessing that current forms of societies that recognise dollars only last two centuries at most.

I don't want to be alive 5 million more years to wait for my dollar. I'll take the 5,000,000 in just one year.

How the hell am i going to live long enough to collect the 5 mil?

By then you only get 1 dollar.

I have no desire to live that long. You'd see modern civilization fall and most likely massively catastrophic events play out.

Maybe if I could keep they knowledge I currently have and the body of 25 year old me then maybe I'd consider it.

If "interest money" and "advertising" disappeared the whole world would implode, or get better. Who knows?
