The MVRV Z-Score compares what all Bitcoin is worth today against what its owners actually paid. The bigger that gap, the higher the score. It is scaled against Bitcoin's own history, so it tells you how unusual today's gap is rather than how large it is in dollars.
Measures how far Bitcoin's price has run ahead of what its owners paid for it.
There are two ways to value the whole network. Market cap is today's price times the number of coins in existence. Realized cap prices each coin at whatever it was worth the last time it moved between wallets, then adds those up, which approximates what owners collectively paid.
The difference is profit that exists on paper but nobody has taken. That dollar figure grows as Bitcoin grows, so the same gap means different things at different network sizes. Dividing by the standard deviation fixes that. Standard deviation is simply a measure of how much a number normally bounces around, so dividing by it converts the gap from dollars into a count of how many typical swings away from normal today sits.
Zero means the two valuations are equal: the average coin is worth exactly what was paid for it. Below zero the network is collectively underwater. The higher the score climbs, the further price has pulled away from what owners paid.
The target zones marked above the chart are where the score has sat at past cycle extremes.
In Bitcoin's earliest completed cycle, the score's highest reading came within days of the final price peak. In every cycle since, the high has arrived well before the market's actual top, in one case the better part of a year early, and had already fallen back by the time price peaked. The low side has been more consistent: the score has spent time at or below zero in the months around each major cycle low.
The peak reading has also come in lower with every successive cycle so far.
The standard deviation grows as Bitcoin's price history lengthens, which mechanically makes any fixed upper threshold harder to reach over time. That is why peak readings keep falling, and it means the high-risk edge reads better as a historical marker than as a level the score is obliged to hit again.
Realized cap treats every on-chain movement as though the coin were bought at that moment. Someone shuffling coins between their own wallets, or Bitcoin moving into and out of exchange and ETF custody, resets the recorded cost basis without anyone actually buying or selling.
