Bitcoin’s layers of concentration

#Bitcoin is sold as decentralised.

In 2025 it is a stack of concentrated power layers that sit on top of each other.

Lets break it down in one big, brutal tweet.

(2h of work..give a like and rt if you like it. Thanks)

🔺 1. Mining power and geography

Recent global hash rate heatmap data for Q4 2025 shows a very tight concentration of physical security.

Top countries by share of global Bitcoin hash rate are approximately:

➡️United States about 37.8%

➡️Russia about 15.5%
➡️China about 14.1%
➡️Paraguay about 3.9%
➡️United Arab Emirates about 3.2%
➡️Oman about 2.9%
➡️Canada about 2.9%
➡️Kazakhstan about 2.1%

The key point: United States, Russia and China together sit at roughly 67% of global hash rate. Kazakhstan, once a major hub, is down to about 2.1% after regulation and energy stress.

It is measured in exahash:

➡️United States around 389 EH/s

➡️Russia around 160 EH/s
➡️China around 145 EH/s

So the majority of new blocks depend on a small group of states, their grids and their politics.

China is officially hostile to open mining, but underground and grey zone operations continue. Aggregated analyses of mining pool data, energy patterns and hardware flows converge on that ≈14% estimate, which means China is still a major structural player in Bitcoin security.

🔺 2. Energy use and sustainability

Cambridge and independent research estimate Bitcoin electricity use in 2025 in a band between about 138 TWh and 175 TWh per year. That corresponds to roughly 0.5% to 0.6% of total global electricity consumption.

That is comparable to the power consumption of a mid sized industrial country such as Poland or Argentina.

A newer Cambridge study reports:
➡️Annual consumption about 138 TWh
➡️Around 0.5% of global power
➡️Network wide emissions around 39.8 MtCO₂e
➡️Sustainable sources (renewables plus nuclear) around 52.4% of the energy mix

Coal has declined sharply compared with earlier years, gas and hydro play a larger role, and a growing share comes from hydro rich regions like Paraguay, which alone holds about 3.9% of the global hash rate with more than 99% hydro power.

Important connection:
Bitcoin is now a visible slice of the global power system. Yet more than half of that power is coordinated inside a handful of grids in a handful of countries.

🔺 3. Industrial hardware and grid dependence

Modern application specific mining hardware changed the structure of mining.

Latest generation ASICs from major manufacturers deliver more than 100 TH/s per machine. A single device replaces entire racks of older hardware. Only operators with large capital, access to credit and direct relationships with manufacturers can stay at the technological frontier.

That feeds into grid concentration.

North America, especially the United States, dominates reported industrial activity. A Cambridge industry report shows that the United States accounts for about 75.4% of reported mining capacity among surveyed firms.

Texas is a central example: multiple gigawatts of mining draw on the same regional grid, with some counties consuming as much power for mining as mid sized cities. Local grid operators have confirmed repeated spikes in load linked directly to large mining campuses during price surges or policy events.

So mining is not just concentrated by country. It is concentrated on specific regional grids and specific industrial scale contracts. That means local regulation, grid failures or political pressure in a few regions can affect global network security.

🔺4. Mining pools and validation power

Even if many firms own hardware, they usually coordinate through mining pools for reward smoothing.

Public pool statistics and independent analyses show that two pools sit on top of block production:

➡️Foundry USA with roughly 30% of global hash rate

➡️Antpool with roughly 20 to 25%

Together that is often 50 to 60% of all blocks, with some periods even higher.

Foundry USA is closely tied to the United States mining boom.
Antpool is operated by the largest ASIC maker.

This does not mean they are attacking the network.
It means that under any form of coordinated pressure, voluntary alignment or targeted incentive change, transaction selection and censorship risk are concentrated in two decision hubs.

🔺 5. ETFs, BlackRock and institutional capture

On the asset side, spot exchange traded funds transformed the way Bitcoin is held.

By late 2025, United States approved spot Bitcoin ETFs together hold more than 1.35 million $BTC . That is over 6% of the fixed 21 million BTC supply.

Within that:
➡️BlackRock iShares Bitcoin Trust IBIT holds around 779 425 BTC
➡️Fidelity Wise Origin Bitcoin Fund FBTC holds around 199 133 BTC

So BlackRock IBIT alone sits on about 3.7% of total Bitcoin supply. Fidelity adds about 0.95%. Together these two funds control more than 4.6% of all Bitcoin that will ever exist.

Coindesk reports that United States spot ETFs together recently held around 1.38 million BTC, dipping slightly to 1.33 million BTC during the latest drawdown.

Capital flows are huge. One week in early October 2025 saw global crypto ETFs pull in about 5.95 billion USD, with around 5.0 billion USD of that in the United States and about 3.55 billion USD into Bitcoin products alone.

The same flows reverse at times.
BlackRock IBIT has already seen single day outflows above 300 million USD and monthly net redemptions above 2.4 billion USD.

Connection:
ETF channels sit at the intersection of traditional finance, politics and Bitcoin. They connect retirement plans, large institutional portfolios and centralised custodians directly to the base asset. That concentrates both ownership and price impact in a small number of regulated vehicles.

🔺6. @saylor and the corporate leveraged reserve strategy.

In parallel with ETFs, one corporate player has positioned itself as a leveraged Bitcoin holding company.

MicroStrategy, now rebranded as @Strategy , has turned its balance sheet into a Bitcoin reserve engine since 2020. Multiple filings and reports during 2025 show:

Around 600k + BTC held, about 3% of total supply, with a market value above 53 billion USD at that time

Later updates pushing holdings to around 597 325 BTC and then above 640 000 BTC by Q4 2025, with a total cost basis around 47.4 billion USD and market value north of 74 to 80 billion USD depending on the price window

Strategy finances these purchases with a mix of:
➡️1. Large at the market equity issuance programs of up to 21 billion USD each, repeatedly renewed
➡️2. Zero coupon convertible bonds such as a 1.9 billion USD issue in early 2025
➡️3. Preferred stock offerings planned up to around 4.2 billion USD

Effectively this is a long term leveraged Bitcoin reserve that behaves like an actively managed synthetic ETF: equity, bonds and preferred stock are transformed into BTC exposure on a rolling basis.

Strategically Saylor has argued that:
Bitcoin only needs a relatively small annual appreciation rate to justify the strategy

Volatility has decreased from about 80% to about 50% since 2020

The company is “indestructible” and can survive drawdowns of 80 to 90% in the Bitcoin price....

Combined with ETFs, this means that more than 10% of all Bitcoin is now concentrated in United States regulated funds plus one highly leveraged corporate balance sheet that is tightly coupled to United States equity markets and regulation.

🔺7. Who else holds the coins

A research overview of top holders in 2025 notes:

➡️Satoshi Nakamoto linked wallets around 1.1 million BTC

➡️Coinbase as custodial exchange around 874 000 BTC
➡️BlackRock, Binance and Strategy together more than 1.89 million BTC

That is a major fraction of circulating supply concentrated in a small number of institutions.

Together with ETFs and corporate treasuries, this creates a network where key decisions by a small set of boards, regulators and large custodians can shift the behaviour of entire supply blocks.

🔺8. Binance and concentrated liquidity

Security and supply are only part of the story. The next layer is liquidity and price discovery.

Public statistics and research show that Binance remains the dominant centralised venue in 2025:

Around 41.1% of global spot trading volume in June 2025

Around 37.34% of global Bitcoin spot volume in the first half of 2025

TokenInsight research cited in a separate analysis estimates that:

Binance cleared about 8.39 trillion USD in trades in Q1 2025

This represented around 36.5% of all global crypto trading activity

Average daily volume around 36.6 billion USD, far ahead of Bybit around 7.9 billion USD, OKX around 6.5 billion USD and Coinbase around 5.6 billion USD

So one venue handles more than one third of all exchange trading and more than two fifths of spot trading.

On top of that, a proprietary analysis you referenced earlier looked specifically at Binance United States dollar tether pairs:

➡️430 USDT spot pairs on Binance

➡️410 of these also had prices on OKX, Bybit, Bitget or Gate

On one critical day 10.10/10.11 (depents on region) 103 Binance pairs printed lows more than 10% below the second lowest exchange

➡️Dozens of pairs had deviations between 50% and 75%

➡️Many pairs fell 75% to 100% below the second venue
More than 30 pairs diverged by more than 100% from the next best price

On that day, liquidation algorithms, oracles and trader psychology used those Binance prints as reference. Without those extreme prints, the liquidation wave would have been far smaller.

Academic work on cross exchange arbitrage under normal conditions finds that such large price gaps rarely persist because arbitrage closes them quickly.

When gaps of 10% to 100% remain for meaningful periods, it means arbitrage capital is overwhelmed, order book depth has collapsed or risk models have frozen.

That is concentrated liquidity risk: the main venue for price discovery becomes a single point of failure.

🔺9. Leverage, liquidations and cascades

In 2025, structural leverage in crypto has been high across centralised futures, perpetual contracts and decentralised finance.

A detailed research paper on the October 10 to 11 2025 event shows:

➡️Around 19 billion USD in open interest erased in about 36 hours

Triggered by a macro shock, in this case an announcement of additional 100% tariffs on Chinese imports

Feedback loops between leverage, thinning liquidity and volatility amplified the move

Galaxy research describes October 10 as:

➡️The largest daily futures liquidation event ever

➡️More than 19 billion USD in liquidations across exchanges
➡️Around 10.27 billion USD of liquidations on Hyperliquid
➡️Around 4.6 billion USD on Bybit
➡️Around 2.3 billion USD on Binance

This sits exactly on top of the liquidity structure described earlier. If one dominant exchange prints extreme lows during an environment with very high leverage and cross exchange derivatives, the result is reflexive deleveraging.

Analyses of liquidation mechanics and circuit breaker proposals show that fragmented liquidity, thin books and strong cross margin engines can turn an external shock into a full internal cascade.

🔺 10. Putting the layers together

Layer by layer the picture is consistent.

➡️ 1. Physical security

Around 67% of hash rate in three states.
Heavy concentration in a few national grids in North America, Russia, China and emerging hubs such as Paraguay and United Arab Emirates.

➡️2. Energy and climate

Around 0.5% to 0.6% of global electricity flows into Bitcoin mining, with more than 50% of that from sustainable sources, but still tightly coupled to fossil based grids and energy policy.

➡️3. Pools and validation

Around 50 to 60% of blocks produced by two pools, Foundry USA and Antpool.

➡️4. Hardware and capital

A short list of ASIC makers, industrial buyers with capital programs in the tens of billions of United States dollars and long term contracts with power providers.

➡️5. Custody and ownership

Around 1.33 to 1.38 million BTC held by United States spot ETFs.
About 779 000 BTC in BlackRock IBIT, about 199 000 BTC in Fidelity FBTC.
More than 600 000 BTC in Strategy.
Hundreds of thousands of BTC in large exchange custodians such as Coinbase.

➡️6. Liquidity and price discovery

Around 36.5% of all crypto trading volume on Binance.
Around 41.1% of global spot volume there.
Deepest books for many altcoins on a single venue.

➡️7. Leverage and reflexivity

Open interest measured in tens of billions of United States dollars.
Documented liquidation cascades that erase 17 to 19 billion USD in a single episode, with Binance as one of the core venues.

Each layer on its own would already matter. Combined they describe a system where:

➡️Security depends on decisions in a small set of governments and grids

➡️Validation is influenced by a handful of pools
➡️Long term ownership is concentrated in a few regulated vehicles and one leveraged corporate treasury
➡️Liquidity and price formation are concentrated on a single centralised exchange cluster
➡️Leverage levels are high enough that stress at one layer propagates quickly into the others

This does not mean Bitcoin is broken. Blocks continue to arrive roughly every ten minutes. The protocol rules still apply.

It does mean that the real world power structure around Bitcoin and the broader crypto market in 2025 is far from the ideal of widely distributed control.

The chain is decentralised in code.
The ecosystem that surrounds it is centralised in practice.

I am here to point things out. This is not FUD.

I am fighting for a better crypto future.

Thanks for reading this far. Very few people do.

To be absolutely clear, I am not FUDing $BTC.
I am simply showing the current state of things.
I enjoy analysing these topics.

I believe in #Bitcoin, and I especially believe in altcoins and crypto as a whole.
There is still a long road ahead, but I think it will turn out well.
