Wouldn't this need to know what I actually did instead? When I use it, it tells me that the form was incomplete. I tried to figure out how much I regret having bought 0 bitcoin so far. Perhaps needs a better error message? I think it actually doesn't like the zero, but prevents it doesn't like incomplete data. Zero is also a number. > CAUSALITY_ERROR: You cannot SELL before you BUY. https://en.wikipedia.org/wiki/Shor…

fixed, btw

My question is, why would you do that to yourself? Living with regrets of the past that would never have been, anyway, seems like a recipe for sadness and despair. Maybe my sense of fun or humor or whatever is off, but I just don't get doing this to yourself, man. You could have hooked into them and thought $1,000 is the highest it'll go and sold them all them. Who knows‽ No offense meant. Just my two Satoshis.

Honestly, it's mostly just dark humor and a bit of financial "exposure therapy". Sometimes seeing the absurdly huge, multi-million dollar number makes the regret feel almost comical rather than actually depressing.

But you are 100% right about the $1k mark. In reality, almost none of us would have held to the top. We would have sold the moment it doubled, bought new iphone and felt like geniuses. That's the reality this calculator conveniently ignores for the sake of the joke!

Appreciate your two Satoshis!

The first thing one has to do when analysing past money decisions is to judge the decision based on the information available at the time. I too watched from the sidelines as btc, nvda and others went to the moon. But with the information available at the time, investing in those was not a sound strategy.

Even if I would've bought Nvidia, Bitcoin, or whatever stock... who is to say I would've had the balls to hold it all the way to whatever they're at today. I probably would've ended up like the guy who spent 10,000 bitcoin on a pizza.

Crudely, if my aunt had a dick she'd be my uncle. In terms of feedback: - need BTC prices pre 2014 to really feel the pain - The date format for earliest date available is different to the date format then used in the input below

You are 100% right about pre-2014 BTC. Any suggestion where to download trusted prices?

Regarding the date format - it can really cause confusion. Let me explaine. The "calculator" date format is "YYYY-MM-DD" (ISO 8601). But the input field's date format adapts based on your device settings. For better UX.

Earlier quoted context omitted.

Would you have $100k now or would you have sold it when it tripled to $3000 because that would've felt like a really good return already, though?

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".

There are plenty of people that thought WeWork would go to the moon, too.

You are 100% right about survivorship bias. That's actually exactly why the calculator already supports a status "BULLET DODGED"!

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.
