Greetings CryptoCubers,

There was a time when you could barely have a conversation about cryptocurrency without hearing one word:

Mining.

Bitcoin mining. Ethereum mining. GPU mining. Mining farms. Graphics cards selling out. Huge warehouses filled with machines.

During previous crypto cycles, mining was everywhere.

Today?

We hear far more about ETFs, staking, stablecoins, DeFi, regulation, institutional adoption and artificial intelligence.

So what actually happened to crypto mining?

Did it disappear?

Did it become unprofitable?

And most importantly: if Bitcoin still depends on miners, what does the future of mining actually look like?

This week, we're going back to one of the foundations of cryptocurrency.

And as you're about to see, mining isn't dead at all.

It has simply grown up.

The Market This Week

Before we head underground, let's take our usual look at the market. 7 day % change

Bitcoin (BTC): approximately $62 990 ⬇️ 2.9%

Ethereum (ETH): approximately $1 878 ⬇️ 2.21%

Solana (SOL): approximately $75 ⬇️ 1.33%

Prices at the time of writing on 16 August 2026. Crypto markets move quickly, so these figures may change after publication.

First: What Actually Is Crypto Mining?

The word "mining" can make the process sound more mysterious than it really is.

Nobody is physically digging Bitcoin out of the ground.

Instead, Bitcoin miners operate specialised computers that perform enormous numbers of cryptographic calculations.

Bitcoin uses a system known as Proof of Work.

When Bitcoin transactions are broadcast to the network, miners compete to create the next block containing transactions.

Their machines repeatedly generate cryptographic hashes, searching for an output that satisfies the difficulty target established by the Bitcoin network.

Think of it like an enormous mathematical lottery.

Millions of trillions of attempts can be made, but eventually one miner finds a valid result.

That miner broadcasts the block to the network.

Bitcoin nodes independently check that the block follows Bitcoin's rules, and if everything is valid, the block becomes part of the blockchain.

Mining therefore helps establish the chronological order of transactions and makes rewriting Bitcoin's history extraordinarily difficult.

And the miner doesn't do all this work for free.

Where Do New Bitcoins Come From?

Here is one of the most important things beginners should understand about Bitcoin:

Bitcoin does not have a central bank printing new coins.

New bitcoin enters circulation through the mining process.

When a miner successfully produces a valid block, the miner receives what is called the block reward.

That reward consists of two parts:

Newly issued bitcoin, known as the block subsidy, and transaction fees paid by people using the network.

When Bitcoin launched in 2009, the subsidy was:

50 BTC per block.

Then came Bitcoin's famous halvings.

2012: 25 BTC

2016: 12.5 BTC

2020: 6.25 BTC

2024: 3.125 BTC

The April 2024 halving cut the subsidy from 6.25 BTC to the current 3.125 BTC per block.

And this is where the mining story becomes particularly interesting.

Because the miner's reward was cut in half.

Their electricity bill wasn't.

The Early Days: Mining Bitcoin From Home

Bitcoin mining looked completely different in 2009.

Satoshi Nakamoto and the earliest Bitcoin users could mine using ordinary computer processors known as CPUs.

There simply wasn't much competition.

As Bitcoin became more valuable, miners discovered that graphics cards — GPUs — could perform the required calculations far more efficiently.

Suddenly, cryptocurrency enthusiasts were building rigs containing multiple graphics cards.

For years, this became one of the defining images of crypto mining.

Rooms filled with GPUs.

Fans everywhere.

Heat everywhere.

Wires everywhere.

And an electricity meter questioning every decision you had ever made.

But eventually even GPUs weren't enough.

Enter the ASIC

Bitcoin mining became increasingly specialised.

Companies developed ASICs — Application-Specific Integrated Circuits.

Unlike a normal computer that can perform thousands of different tasks, a Bitcoin ASIC is designed primarily to perform Bitcoin's SHA-256 hashing calculations extremely efficiently.

This completely changed the industry.

The era of casually mining meaningful amounts of Bitcoin using your gaming computer was effectively over.

Mining began moving toward industrial-scale operations containing thousands — sometimes tens of thousands — of specialised machines.

Cheap electricity became critical.

Cooling became critical.

Access to power infrastructure became critical.

Engineering became critical.

And mining slowly transformed from something enthusiasts could do from a bedroom into an enormous global infrastructure industry.

Mining pools also became increasingly important. Instead of individual miners hoping to win an entire block themselves, miners could contribute computing power to a pool and receive a proportional share of the pool's mining income.

Then Ethereum Mining Exploded

Bitcoin wasn't the only major cryptocurrency using Proof of Work.

For years, Ethereum could also be mined.

And unlike Bitcoin's increasingly ASIC-dominated mining industry, Ethereum became enormously popular with GPU miners.

This helped create the massive GPU mining boom many CryptoCubers may remember.

People built mining rigs containing six, eight, twelve or even more graphics cards.

At certain points during the 2020–2021 crypto boom, demand from miners became so intense that high-end graphics cards became notoriously difficult and expensive to find.

Then Ethereum changed everything.

September 2022: Ethereum Mining Ends

On 15 September 2022, Ethereum completed one of the biggest technological changes in cryptocurrency history:

The Merge.

Ethereum abandoned Proof of Work and transitioned to Proof of Stake.

Instead of miners securing Ethereum with enormous quantities of computing power, validators began securing the network by staking ETH.

Ethereum estimates that the transition reduced the network's energy consumption by approximately 99.95%.

For Ethereum miners, however, it meant something much simpler:

Ethereum mining was over.

Some miners shut their machines down.

Others sold their GPUs.

Others moved their computing power toward alternative Proof-of-Work cryptocurrencies.

Research following The Merge found that substantial amounts of former Ethereum mining power initially migrated toward other Proof-of-Work networks, although profitability dropped significantly as all that computing power began competing for much smaller rewards.

This was one major reason mining suddenly seemed to disappear from everyday crypto conversations.

One of the world's largest mineable cryptocurrencies simply wasn't mineable anymore.

But Bitcoin Never Stopped Mining

Bitcoin took the opposite path.

Proof of Work remains fundamental to Bitcoin.

Every day, enormous amounts of computing power continue competing to produce Bitcoin blocks.

And if more mining machines join the network, Bitcoin automatically becomes harder to mine.

If large amounts of computing power disappear, the network can lower the difficulty.

This adjustment mechanism helps Bitcoin maintain an average block interval of roughly ten minutes.

That is one of the brilliant parts of Bitcoin's original design.

Bitcoin doesn't require a particular mining company to survive.

Individual miners can enter.

Individual miners can leave.

Companies can go bankrupt.

Machines can become obsolete.

Entire countries can change their mining policies.

Yet the network continues adjusting.

So What Is Happening to Bitcoin Mining in 2026?

This is where things get particularly interesting.

Bitcoin mining has become enormously competitive.

Bitcoin's network computing power has reached the extraordinary zettahash-per-second scale during 2026, while mining difficulty has remained historically high.

But higher competition means each individual machine receives a smaller proportion of the total mining pie.

At the same time, the 2024 halving reduced the block subsidy to just 3.125 BTC.

The result?

Mining margins have become extremely tight.

CoinShares estimated that the weighted average cash cost of producing one bitcoin among the publicly listed miners it tracks reached roughly $80,000 during Q4 2025, although individual miners' economics can vary enormously depending on electricity prices, equipment efficiency, financing and location.

With Bitcoin currently trading around $63,000, you can understand why inefficient mining operations are under serious pressure.

Mining isn't simply about asking:

"Will Bitcoin go up?"

A professional miner has to ask:

What does my electricity cost?

How efficient are my ASICs?

What is Bitcoin's price?

What is the current network difficulty?

How much computing power is competing against me?

How much are transaction fees generating?

How much does maintaining and cooling my facility cost?

Suddenly it starts looking far less like somebody running a computer in their bedroom.

And far more like an industrial energy business.

And Then AI Entered the Mining Industry

This may be the biggest change happening in mining today.

Many of the world's major Bitcoin miners already possess something that AI companies desperately need:

Power.

Massive amounts of it.

They also own or control land, substations, grid connections, cooling infrastructure and data-centre facilities.

Those assets are incredibly valuable in the artificial-intelligence boom.

So some mining companies are beginning to diversify away from Bitcoin mining and toward AI and high-performance computing — HPC.

CoinShares reported that publicly listed mining companies announced more than $70 billion in aggregate AI/HPC agreements through 2025 and early 2026. The firm believes AI could eventually represent a huge proportion of revenue for some companies traditionally regarded as Bitcoin miners.

And this trend is accelerating.

In July, Hut 8 announced another $9.8 billion AI data-centre lease associated with its Texas campus.

And just this month, Riot Platforms — one of the names historically synonymous with Bitcoin mining — announced a $9.1 billion, 20-year computing agreement with AI company Anthropic.

That is an extraordinary evolution.

Are Miners Turning Their Bitcoin Machines Into AI Computers?

Not exactly.

This is an important distinction.

A Bitcoin ASIC isn't simply being switched from "Bitcoin mode" to "ChatGPT mode."

Bitcoin ASICs and AI GPUs are very different pieces of hardware designed for very different workloads.

What makes mining companies attractive to AI is largely the infrastructure surrounding those machines.

The power.

The land.

The buildings.

The cooling.

The grid access.

The expertise in operating power-hungry computing facilities.

In other words, some Bitcoin miners are discovering that their most valuable asset may not necessarily be their mining machines.

It may be their access to electricity.

And that could completely reshape the industry.

Does AI Threaten Bitcoin Mining?

Potentially — but probably not in the way people might initially imagine.

If an AI company is willing to pay substantially more for electricity and data-centre capacity than Bitcoin mining can generate, some operators have a simple financial decision to make.

Why use the facility to mine Bitcoin when the same power infrastructure can potentially produce more predictable income serving AI?

That competition could push Bitcoin miners toward areas where electricity is cheaper, power would otherwise be underused, or mining can operate flexibly when energy demand is low.

CoinShares believes AI competition could gradually push Bitcoin mining toward cheaper and more intermittent energy sources.

But here's another important point:

Bitcoin doesn't need Riot.

Bitcoin doesn't need Hut 8.

Bitcoin doesn't need any particular mining company.

If some miners leave and total computing power declines, Bitcoin's mining difficulty can eventually adjust downward.

That makes mining more attractive again for whoever remains.

The network is designed around competition.

Is Crypto Mining Still Profitable?

Sometimes.

But the days of simply purchasing a few GPUs, plugging them into the wall and expecting easy passive income are largely behind us — particularly for Bitcoin.

Professional mining has become a game of extreme efficiency.

Two mining operations could own exactly the same machines and experience completely different results simply because one pays significantly less for electricity.

Mining profitability now depends heavily on the relationship between:

Bitcoin's price, electricity cost, ASIC efficiency, network difficulty, transaction fees, facility costs and capital expenditure.

This also explains why many smaller or inefficient mining operations disappear after halvings.

The network doesn't stop.

The weakest miners get squeezed out and the remaining operators compete for the available rewards.

What About Mining Other Cryptocurrencies?

Bitcoin is the largest and most important Proof-of-Work network, but it isn't the only mineable cryptocurrency.

Other Proof-of-Work ecosystems still exist.

Some use ASICs.

Some remain more GPU-focused.

Some have attempted to remain accessible to CPU miners.

But much of the broader cryptocurrency industry has moved toward Proof of Stake and other consensus mechanisms, where users participate through validators or staking rather than traditional mining.

That is why the phrase "crypto mining" is heard less often today than it was five years ago.

Crypto did not abandon mining completely.

Crypto diversified beyond it.

Bitcoin, however, remains firmly committed to Proof of Work.

The Next Big Test: The 2028 Halving

And the pressure isn't going away.

Bitcoin's next halving is expected around 2028.

When it occurs, the current 3.125 BTC block subsidy will fall again to approximately:

1.5625 BTC per block.

Once again, miners will receive half as much newly created Bitcoin for performing the same fundamental job.

That means the industry has another major efficiency test approaching.

Some miners will need cheaper power.

Some will need more efficient ASICs.

Some may diversify into AI.

Some may shut down.

Some may merge with larger companies.

And some highly efficient operators may emerge stronger.

The halving doesn't just make Bitcoin scarcer.

It forces the mining industry to evolve.

What Happens When There Are Eventually No New Bitcoins to Mine?

This is where Bitcoin's long-term design becomes fascinating.

Bitcoin's block subsidy keeps halving.

Eventually, newly issued Bitcoin will become an increasingly tiny portion of miner income.

At that stage, miners are expected to rely increasingly on transaction fees from people using the Bitcoin network.

Remember:

Mining rewards already consist of both the block subsidy and transaction fees.

The subsidy simply dominates most blocks today.

Over the coming decades, that balance is designed to change.

Exactly how a mature fee-driven Bitcoin mining market develops remains an active area of economic and technical research.

Bitcoin is therefore slowly moving toward an economic system where miners are rewarded increasingly for securing and processing activity on the network rather than receiving newly created Bitcoin.

So... What Happened to Crypto Mining?

It didn't disappear.

It evolved.

Bitcoin mining began with enthusiasts running ordinary CPUs.

Then came GPUs.

Then ASICs.

Then enormous mining farms.

Ethereum created another massive GPU mining industry before abandoning Proof of Work entirely.

Bitcoin's halvings repeatedly squeezed mining rewards.

Competition exploded.

Electricity became one of the most valuable resources in the industry.

And now, in one of the strangest twists in crypto history, companies that built enormous infrastructure to mine cryptocurrency are finding themselves perfectly positioned to help power the artificial-intelligence revolution.

The image of the crypto miner has changed.

Yesterday's miner was somebody surrounded by graphics cards in their bedroom.

Today's miner may operate hundreds of megawatts of power infrastructure.

And tomorrow's "mining company" may simultaneously secure Bitcoin, operate data centres and provide computing infrastructure to some of the largest AI companies on Earth.

The CryptoCube Take

Mining is one of the best examples of why cryptocurrency cannot be understood by watching price charts alone.

Behind Bitcoin's price sits an enormous network of machines, electricity, economics, incentives and competition.

Every Bitcoin transaction depends on that system continuing to function.

Every halving changes the economics.

Every generation of mining hardware raises the standard.

And every miner competing for the next block contributes to the security of the Bitcoin network.

So when somebody asks:

"Whatever happened to Bitcoin mining?"

The answer isn't that it died.

The answer is much more interesting.

Bitcoin mining became an industry.

And now that industry is entering its next evolution.

Keep learning. Keep questioning. And most importantly, keep understanding what you own.
