Yeah this is the story I tell myself to make me feel better. I may well have even more regret! Or thought I was an investment genius and invested loads more and then sold it at a bad time.

yeah as Warren Buffett once said: "Our favorite holding period is forever".

That is basically my strategy. Everything I buy is with the intent of selling in a couple of decades when retirement comes, at the earliest.

It's true, most investors quit right before they're about to hit it big! ...or alternatively, you live a decent life without associating with any of this.

Ah, the classic "99% of gamblers quit right before they win big" mindset! :)

But honestly, your second point is the ultimate truth. Ignorance truly is bliss. The happiest people are usually the ones who have zero idea what the current price of Bitcoin or Nvidia is, not even BTC or NVDA, hehe.

I applaud the technical journey, but I really do not understand the purpose. What's the point of knowing last week's lottery numbers?

Think of it as art :) It’s an interactive museum of missed opportunities. We all know we can't change the past, but it's strangely entertaining to calculate exactly how much a 2015 pizza cost us in today's Bitcoin.

The opportunity cost is what I can do instead. The opportunity cost of investing is just a 3% return really. So much that we do in life is just throwing the money away though. You should just go to work, invest all your money, then when you are 65 you will be able to live off your savings.

I spent 20 years of my adult life on a cold and calculating lifestyle (as you described), I can’t say that I was unhappy, but one morning I woke up and realized that everything that had been acquired was lost due to circumstances beyond my control.

So?

If you'd bought every fad coin your brother recommended to you, even though it was a bad idea in your own judgement then I think you'd have zero dollars.

My brother is not a crypto guru, we just discussed about BTC. It was a philosophical conversation in the spirit of perhaps it will become an alternative to conventional money, then it could greatly increase in value.

But I agree that buying new coins is like buying lottery tickets - if you buy all the tickets, there will be no money left.

Art needs no justification. So, well done ;)

It's a great strategy as long as there's agreement between people and that the "S&P500" (paste your) means something :)

Most reasonable people will not have enough conviction to make a serious amount of money even if they’re right. I think a better question is how much would you have invested to make $500k/ $1mn (or whatever a life changing sum is for you) on the investment then you can consider whether you had the stomach to do that.

By the way, a "Reverse Mode" (calculating the initial stake needed to hit exactly $1M) is actually a brilliant idea. But to your underlying point - it's the hard truth. People often act like they have infinite time and keep putting decisions off for "later". And then, boom - your peak earning years are behind you, boom - you're 70. This terminal is basically a receipt for that exact kind of procrastination.

It is sort of brilliant (thanks btw) but also stupid to think about. It is easy for people to simply put a sensible monthly amount in a low cost fund and given enough time and steady contributions make life changing amounts of money (early retirement, house upgrade, child’s school or college paid for etc). And all without needing to take a big bet at any point.
