BTC is a (roughly) net-zero enterprise, every dollar taken out of the system comes from someone else putting a dollar in. Sure, if you had a crystal ball you could have made millions, but if everyone else ALSO had that same crystal ball you couldn't, since traders are mostly just shuffling money between themselves anyway.

There's no point kicking yourself over not foreseeing a far-fetched future scenario, if you were at a casino and a roulette spin landed on 12 - would you feel bad for not betting on that happening, despite having no good information it would land on that?

A lot of the stock market is built on this model too surely?

I get some of it works off dividends etc, but so much is sentiment driven and also based off of someone else making a loss.
