Miners have been getting paid since day one to keep the Bitcoin network running — that's a real, measurable cost. Add up every payment miners have ever received, and you get the total cost of building Bitcoin's security. This metric shows you how much the market values each dollar of that investment.

When this ratio is really high, the market is pricing Bitcoin way above what it actually cost to build. That's been a sign of speculation getting out of hand — people are paying a premium that history suggests won't last.

When it's low, the market value has shrunk down close to the actual cost of all the work that went into making Bitcoin exist. These are moments of strong fundamental value — you're basically buying Bitcoin at close to the cost of everything that was spent to create it.

This is different from most other indicators because it measures real-world costs — actual energy and money that miners spent. It's grounded in physical reality, not just what people paid to trade coins back and forth. That makes it a useful sanity check on whether the price makes sense.
