What the main Bitcoin cycle models measure
The following definitions explain the inputs, not a ranking of forecasting accuracy. Use one named price feed and daily cutoff for comparisons. An intraday 200-bar average is not a 200-day average, and a chart with too little history cannot supply a complete long lookback.
| Model | Calculation or construction | What the reading does not establish |
|---|---|---|
| Pi Cycle Top | 111-day moving average crosses above twice the value of the 350-day moving average | Twice the average value is not a 700-day average; a cross is not proof of a final high. |
| Mayer Multiple | Bitcoin price divided by its 200-day moving average | A multiple measures distance from a baseline, not the probability of a decline. |
| 2-Year MA Multiplier | Compare price with the two-year moving average and five times that average | A historical band is not a guaranteed future ceiling. Verify the provider’s day-count convention. |
| MVRV Z-Score | (market cap − realized cap) / standard deviation of market cap | The denominator’s history and provider implementation matter; this is not a normal-distribution confidence level. |
| NUPL | (market cap − realized cap) / market cap | A value of 0.75 is not evidence that 75% of holders, or nearly all holders, have a profit. |
| RHODL Ratio | Realized-value HODL band of one week divided by the one-to-two-year band, adjusted by market age in days | Coin age is not the age or identity of an investor; transfers need not represent a sale. |
