Bitcoin on-chain analysis: the complete guide

Bitcoin's ledger is fully public, which means you can study real holder behavior instead of guessing. This guide explains the core metrics — HODL waves, exchange flows, ETF flows, miner economics — and how to read them honestly, then links to our data breakdowns.

What on-chain analysis actually is

Every Bitcoin transaction is recorded on a public ledger. On-chain analysis turns that raw history into behavioral signals: how long coins sit unmoved, whether they are flowing toward exchanges (often a precursor to selling) or away from them (often accumulation), and how miners are behaving. None of this is a crystal ball — it is context. The discipline is in combining metrics and resisting the urge to read a single chart as a buy or sell signal.

Supply & holder behavior

The most-watched lens is how the supply is distributed by age. HODL waves band the circulating supply by how long each coin has been held. When the long-held share grows, it implies conviction holders are accumulating; when it shrinks sharply, long-term holders may be distributing into strength. Our HODL waves analysis walks through how to read these bands.

Exchange & ETF flows

Coins moving onto exchanges increase potential sell-side liquidity; coins moving off exchanges often signal a shift to self-custody and longer holding. Since spot ETFs launched, a parallel flow matters too: ETF creations and redemptions translate into custodial BTC movements. We mapped a large single-day inflow against on-chain custody data in our ETF inflow breakdown.

Miner & network health

Miners are forced sellers when margins compress, so their behavior matters. Two angles: hashrate (the total computing power securing the network, a proxy for security and miner commitment) and post-halving economics (how a reward cut squeezes higher-cost operations). See our hashrate & mining-pool concentration piece and our post-halving miner economics model.

Core metrics glossary

Realized cap
Values each coin at the price it last moved, rather than the current price — a "cost basis" view of the whole network.
MVRV
Market value divided by realized value. High readings suggest the average holder is in large profit (historically frothy); low readings suggest capitulation territory.
SOPR
Spent Output Profit Ratio — whether coins moving on a given day are, on average, being spent in profit or at a loss.
NUPL
Net Unrealized Profit/Loss — the aggregate paper profit or loss of all holders, used to gauge market sentiment phases.
Exchange reserves
The total BTC held in known exchange wallets; falling reserves are often read as accumulation.
