I got into crypto in 2020. I had a price chart, a Fear & Greed Index bookmark, and exactly zero understanding of what was happening onchain. I watched MVRV Z-Score, exchange reserves, and STH-SOPR move in ways that would have told me exactly what was coming. And I missed every signal because I didn’t know what any of it meant.
This post is the guide I wish I’d had.
I’m not going to cover every onchain metric. I’m going to cover the three that would have changed the most about how I analyzed the market during my first cycle, and why they’re still the first three I check today.
Metric 1: MVRV Z-Score
When BTC climbed toward $69K in November 2021, I had no framework for understanding whether that price was expensive or cheap relative to what the network actually looked like. I was using price targets from social media analysts and nothing else.
MVRV Z-Score measures the difference between Bitcoin’s market cap and its realized cap. The realized cap is the aggregate cost basis of every coin that has ever moved, weighted by when it last moved. When the gap between market cap and realized cap gets extreme, the Z-Score spikes. When it collapses, the Z-Score drops.
The pattern is consistent across every Bitcoin cycle. When MVRV Z-Score pushes above 7, you are in the red zone. Historically, every major Bitcoin cycle top has printed there. When it drops into the blue zone below 0, you are at or near cycle lows. The 2018 bottom, the March 2020 crash, and the 2022 FTX bottom all printed in or near the blue zone.
In November 2021, MVRV Z-Score was above 7. The signal was clear. I wasn’t looking. If I had understood this metric during my first cycle, I would not have been buying at $60K+ thinking it was the start of a new leg up. I would have recognized that the market was in historically overvalued territory.

Metric 2: Bitcoin Exchange Reserves
Before I understood exchange reserves, I tracked price and volume. That was it. I thought the order book told me everything about supply and demand. It doesn’t.
Exchange reserves measure how many Bitcoin are sitting on centralized exchanges, available to be sold. When reserves are falling, coins are leaving exchanges and moving into cold storage. That is structural accumulation. When reserves rise, more sell pressure is building on the visible market.
Since 2022, Bitcoin exchange reserves have been in a multi-year structural decline. Roughly 2.2 million BTC remain on exchanges as of mid-2026, the lowest level in nearly eight years. Every sustained bull market since 2019 has been accompanied by falling exchange reserves. Every meaningful distribution phase has seen them rise.
This is the metric that explains why Bitcoin’s April 2026 recovery from $65K to $80K happened with less volatility than past cycles. There simply wasn’t as much sell-side supply available on exchanges. The data showed it. The price confirmed it weeks later.
I think about exchange reserves as the “available float” metric. If there are fewer coins available to sell, each buyer has more price impact. When exchange reserves hit multi-year lows while demand holds steady, something has to give. It usually gives upward.

Metric 3: STH-SOPR
This is the one I feel most strongly about for anyone in their first or second cycle.
Every time BTC drops sharply, the same narrative appears: this is different, this is the real crash, it’s going lower. In 2022, that narrative was accompanied by genuine capitulation data. In most mid-cycle corrections, it isn’t. Learning to tell the difference is one of the most valuable skills in onchain analysis, and STH-SOPR is the cleanest way to do it.
STH-SOPR measures whether short-term Bitcoin holders, meaning coins held for less than 155 days, are selling at a profit or a loss. When the ratio is above 1.0, the short-term holder cohort is in the green. When it drops below 1.0, they are selling at a loss on average. The longer and deeper it stays below 1.0, the more genuine the capitulation signal.
Here is what changed for me when I understood this metric: I stopped reacting to the narrative and started asking a specific question. Are short-term holders actually capitulating at a scale consistent with structural bottoms? Or is STH-SOPR just mildly negative, which happens during every routine mid-cycle pullback?
In Q1 2026, Bitcoin fell more than 40% from its all-time high. STH-SOPR stayed below 1.0 for most of the quarter. But it never reached the extreme territory that preceded the 2018 and 2022 lows. The panic was real. The capitulation signal was not. The metric told the difference. Price confirmed it when BTC recovered from $65K to $80K+ through April and May 2026.

Why These Three?
Every onchain metric tells a different part of the same story. MVRV Z-Score covers valuation: is Bitcoin historically expensive or cheap? Exchange reserves cover supply: how much sell pressure could realistically enter the market? STH-SOPR covers behavior: what are newer participants actually doing, and is the fear backed by data or just sentiment?
Together, these three cover valuation, supply, and behavior. They are not the only metrics that matter. But they are the ones I would tell any first-cycle investor to learn before anything else. The good news is that all three are available for free. MVRV Z-Score and STH-SOPR are on Look Into Bitcoin and Glassnode’s free tier. Exchange reserve data is available via CryptoQuant and Glassnode.

The Takeaway
Onchain analysis is not about predicting price. It is about replacing narrative with data. MVRV Z-Score, exchange reserves, and STH-SOPR do not tell you what Bitcoin will do next week. They tell you what the network and its participants are actually doing. That is almost always more useful than what people are saying on social media.
If you are in your first or second cycle, these are the three I would start with. Not because they are the most sophisticated tools available. Because they are the most honest.
