The Mayer Multiple is Bitcoin’s price divided by its 200-day moving average. It shows how far spot has moved from a widely followed long-term trend line.

The appeal is its simplicity: it uses price alone. That also limits it, because the ratio cannot explain what caused the move or whether the 200-day average is a fair-value anchor.

How the Mayer Multiple is calculated

Formula. Bitcoin Price ÷ 200-Day Moving Average.

A reading of one means price is on the 200-day average. A reading of 1.5 means price is 50% above it; 0.8 means price is 20% below it.

Why historical extremes change

Bitcoin’s highest Mayer Multiple readings have generally compressed as the market has matured, but that is an observation rather than a rule. Market size alone cannot guarantee smaller percentage moves.

Volatility, liquidity and market structure all change. Recent percentiles and the shape of the trend are safer than assuming an old cycle threshold must repeat.

What it does not tell you

The ratio contains no on-chain cost basis, demand, leverage or macro data. A high reading caused by broad adoption looks the same as one caused by a leveraged squeeze.

The upside and downside are also asymmetric: price can rise many times above an average but cannot fall below zero. Treat the two sides of the range separately.

How to read it

Far above the 200-day average. Price is historically extended for the chosen lookback.

Above the average. Price is trading ahead of its long-term trend.

Near one. Price and the 200-day average are close.

Below the average. Price is trading beneath its long-term trend.

Historically low. A deep discount to the 200-day average; not automatically fair value.

Common questions

Why use 200 days?

It is a durable market convention: long enough to smooth shorter swings while still moving within a Bitcoin cycle. The number is useful, not sacred.

Have peak readings fallen every cycle?

They have generally compressed in the observed history. That pattern can continue, pause or reverse; it is not a mathematical law.

Is a reading below one a buy signal?

No. It says price is below its 200-day average. Markets can remain there for long periods.

How does this differ from MVRV?

Mayer compares price with a moving average of price. MVRV compares Market Cap with a last-moved-price cost-basis proxy.

Can it be used for other assets?

The formula can, but Bitcoin’s historical bands should not be copied to assets with different volatility and trading histories.
