full power of the Bitcoin Blockchain

If you spend enough time around Bitcoin, you eventually realize something most beginners miss: price doesn’t tell you how healthy the network is.
Price tells you what traders are feeling. FRM tells you what the network is actually doing.
The Fee Ratio Multiple (FRM) is one of those unsexy, misunderstood metrics that quietly captures one of the biggest questions in Bitcoin’s long-term future:
Is the network securing itself through real economic activity - or is it still relying on inflationary block rewards?
If you care about miner sustainability, long-term security, network maturity, or the economics of block space, this metric belongs in your toolkit.
Let’s break it down - clearly, practically, and without drowning in jargon.
Let’s keep this straightforward.
FRM answers one question:
Are miners earning more from block rewards, or from actual user demand (fees)?
The formula is simple:
Meaning:
This metric was introduced by David Puell, and it has become a foundational tool for analyzing Bitcoin’s economic maturity - especially as halvings steadily reduce block rewards.
Key Insight: A sustainable Bitcoin economy requires fees to eventually replace block rewards. FRM helps us track that shift.
The FRM chart is simple on the surface:
You look at the line, see how high or low it is, and understand whether:
But behind that simplicity sits a lot of economic nuance. FRM effectively visualizes network demand, fee pressure, and miner sustainability all at once.
In other words: it’s one line with a lot of meaning.

FRM is a rare metric because it answers both short-term and long-term questions at the same time.
Here’s why it’s powerful:
If miners rely on block subsidies, Bitcoin’s security is tied to halvings.
If miners rely on fees, security becomes organic and sustainable.
Fees don’t rise unless users demand block space.
FRM captures this demand directly.
As halving events cut block rewards, miner incentives must shift toward fees.
FRM lets you watch that transition.
If block rewards drop and fees don’t increase, sustainability weakens.
This isn’t about price - it’s about Bitcoin’s economic backbone.
Interpreting FRM is easier than most on-chain metrics.
There are only three states that matter.
Miners depend mostly on block rewards.
This environment typically reflects:
High FRM is normal when Bitcoin feels boring.
But if it stays high for too long, it raises concerns about long-term miner sustainability.
A meaningful portion of miner revenue is coming from fees.
This is what a maturing network looks like:
Low FRM is often seen during:
This is the direction Bitcoin must move long-term.
A balanced environment where neither block rewards nor fees dominate.
This is often a transitional signal - either demand is rising out of a bear market, or calming down after a high-fee period.
A high FRM tells a very specific story:
This is typical during quieter market phases.
But it also reveals something about long-term security:
If fees don’t rise over time, Bitcoin becomes dependent on forever-inflating block subsidies.
And that’s not sustainable after multiple halvings.
A persistently high FRM is a warning sign - not for price, but for Bitcoin’s economic maturity.
Low FRM is a completely different story.
It tells you:
Low FRM often appears during:
A consistently low FRM is a sign of a healthy, economically engaged Bitcoin network.
To understand FRM deeply, you need to look at miner incentives:
Inflationary, declines every halving, predictable.
Market-driven, variable, based on real user demand.
FRM essentially measures how dependent miners are on inflation vs. users.
Healthy long-term dynamics:
FRM helps analysts see how close we are to that reality.
Let’s look at how FRM has behaved across Bitcoin’s major eras.
Fees increase significantly as:
FRM drops, often dramatically.
These periods reflect Bitcoin’s real economic pressure - not just price hype.
Fees collapse, and block rewards become the dominant revenue source again.
FRM spikes upward, sometimes sharply.
This doesn’t mean the network is unhealthy - just that usage is quiet.
Across cycles, something important is happening:
FRM is slowly trending downward over multi-year periods.
This reflects:
It’s exactly what you want to see in a maturing network.
FRM is more practical than people realize.
Here’s how professionals use it:
If FRM is dropping, demand is increasing.
Fees often rise before price does.
Can miners survive on fees?
FRM has the answer.
Is Bitcoin transitioning from a subsidy-driven economy to a fee-driven one?
Analysts often pair FRM with:
FRM is never used alone - but it strengthens almost every macro conclusion.
No metric is perfect. FRM has some caveats.
A single memecoin frenzy or inscription spike can distort FRM temporarily.
Lightning, batching, and L2 solutions reduce on-chain fee volume.
FRM doesn’t tell you where price goes tomorrow.
FRM is most meaningful during periods where both rewards and fees matter.
Compare FRM alongside difficulty, miner revenue, and hash rate for the full picture.
These are the kinds of insights analysts rely on:
Fee volatility can temporarily distort the metric.
This often shows miners shifting into sustainable fee-based income.
You can’t fake fee pressure - FRM exposes real network usage.
If FRM is high but revenue is low → miner stress is coming.
These often precede:
It measures how much of miner income comes from block rewards vs. transaction fees.
Miners rely mostly on block subsidies → low economic activity.
Fees contribute heavily to miner revenue → high demand and sustainability.
Generally yes, it means Bitcoin is transitioning toward fee-driven security.
Not directly, but it reflects adoption waves that often precede major market moves.

Primarily Bitcoin and other chains where block rewards play a central role.
The Fee Ratio Multiple is one of Bitcoin’s clearest mirrors into its economic health.
It cuts through noise, speculation, and narratives by asking one simple question:
Is Bitcoin being secured by users, or by inflation?
Understanding FRM doesn’t just make you a better analyst - it helps you understand Bitcoin’s long-term sustainability in a way most people overlook.
