It's also worth remembering that some people ARE traders.

But just because you use an asset, money, or contract doesn't mean you have to trade it. And that trading IS a profession, a skill, and something you can absolutely hurt yourself doing.

It's also something very prevalent in the fiat world where saving isn't a real option because the money itself is a melting ice cube.

Fwiw, it's worth remembering that a skillful market of traders can bring some smoothness to otherwise jagged price movements particularly as changing fundamentals bring about broader shifts in valuation. If you were able to buy at 75k between 60k and 90k you likely have some traders to thank. Some of whom may very well have lost money in providing that service to you, though perhaps others who did not, but were more interested in focusing on those short term price moves.

They're a wild bunch to watch work, but I'm glad not to be one of them.
