A Dialogue with CHAT GPT on Bitcoin

By

Ashok Nag

This is a dialogue that I had with CHAT GPT

My Question:   How many crypto currencies are now available? List the top 10 ones.

CHAT GPT:    Bitcoin (BTC)-1, Ethereum (ETH)-2, Tether(USDT)-3, Binance Coin(BNB) 4,  Solana(SOL) -5,

 XRP (CRP) -6. USD Coin (USDC) -7, Cardano (ADA) -8, Avalanche( AVAX), Dogecoin (DOGE)-10.

My Question:  What is the market share of the top 10 crypto you gave?

CHAT GPT: As of January 2025, the total cryptocurrency market capitalization was approximately $3.5 trillion.  The top ten figures are:

Bitcoin -$2.02 trillion, accounting for roughly 57.5% of the total market.

Ethereum – Around $400 billion market cap, accounting for roughly 12% of the market.

Tether- Market cap of approximately.  $137 billion

For others, information about market price only is available

a warning – The cryptocurrency market is highly volatile. So a complete picture of the market is not readily available.

My Question: Bitcoin has an upper limit as per its architecture designed by its founder Satoshi Nakamoto

CHAT GPT: Yes, exactly. Bitcoin was designed with a hard cap of 21 million coins. This is built into the Bitcoin protocol and cannot be changed without a consensus on the entire network, which is extremely unlikely.

Here is how it works:

Block rewards are halved approximately every 4 years (every 210,000 blocks). This is called the halving event. When Bitcoin launched in 2009, the reward was 50 BTC per block. As of the most recent halving in April 2024, the reward dropped to 3.125 BTC per block.

This process will continue until around the year 2140, at which point all 21 million bitcoins will have been mined. This finite supply is a key reason why Bitcoin is often compared to digital gold — it is scarce, and the supply is known and predictable.

Want to know how many have been mined so far or how the halving schedule looks?

My answer: Sure.

CHAT GPT:  Here is a breakdown of Bitcoin’s halving schedule and how it affects the total supply: Bitcoin Halving Schedule & Supply

Halving EventYearBlock HeightBlock Reward (BTC)Total BTC in circulation
Genesis2009050 BTC0
1st HalvingNovember 2012210,00025BTC10.5 million (approx.)

5th Halving ( estimated)20321,260,0000.78125 BTC20.67 million
Final BTC Mining21406.93 million blocks0BTC21 million

As of April 2025:

Total Bitcoins mined: 19.7 million (approx.)

Remaining to be mined: 1.3 million

Why this matters:

  • The fixed cap +predictable halving=scarcity

Over time, BTC becomes harder to mine and more valuable, assuming demand stays constant or increases.

My Question: What happens after all 21 million BTC are mined (around the year 2140)?

CHAT GPT: Here it is what is expected:

1. Miners will still be incentivized — via Transaction Fees. Even after block rewards end, miners will not stop working. They will earn income from transaction fees, which users pay to have their transactions processed and confirmed.

These fees are already a significant part of miners’ earnings, especially during high-demand periods.

2. Bitcoin Will Become a Pure Settlement Network. Over time, Bitcoin may evolve into more of a settlement layer, handling large and high-value transactions. Smaller, everyday transactions may shift to Layer 2 solutions like the Lightning Network, which settle off-chain and occasionally use Bitcoin’s main chain for final settlement.

3. Security Concerns?

There has been some debate about whether transaction fees alone will be enough to keep miners incentivized to secure the network. However, if Bitcoin’s price and adoption continue to grow, transaction fees could be very lucrative, possibly offsetting the lack of block rewards.

Bitcoin will not die after 21 million — it will rely entirely on transaction fees to keep the system running.

Miners stay active, and Bitcoin keeps ticking as long as there is demand to use it.

My Question: If Bitcoin is like a digital gold, why should it remain as money while gold has ceased to function as money, although it remains as a store of value?

CHAT GPT:  That is a thoughtful question — and you are touching on a key debate in crypto and economic circles.

Let us break it down:

Why Gold Ceased to Function as Money

Gold was money for centuries — as coins, bars, and eventually backing paper currencies. But it stopped being used as everyday money because:

  • Not easily divisible or portable for daily use.
  • Hard to verify authenticity without tools.
  • Cumbersome to transfer over long distances or digitally.
  • Governments moved toward fiat currencies for flexibility (like printing more money in crises).

So today, gold is a store of value, not a medium of exchange.

Why Bitcoin Might Be Different

1. Digital by Nature

  • Bitcoin is natively digital, instantly transferable, and globally accessible.
  • You can send it across the world in minutes without intermediaries.

2. Scarce and Verifiable

  • Like gold, it’s scarce (21M cap), but easier to verify and impossible to counterfeit.

3. Divisible and Programmable

  • Bitcoin is divisible into 100 million satoshis per BTC — easy to use in small amounts. It is programmable — great for smart contracts and future use cases.

4. Censorship-Resistant

No central authority can freeze or block your Bitcoin — unlike bank accounts.

So Why Might Bitcoin Still Become (or Stay) “Money”?

While gold failed as a medium of exchange in the modern age, Bitcoin fixes many problems that gold could not solve.

That said, it may never be “money” like cash or credit cards in daily life. Instead, it could evolve into:

  • A global settlement asset (like digital gold for institutions).
  • The base layer of a broader financial system (e.g., Lightning Network for daily payments).
  • A hedge against fiat inflation for individuals and nations (like we’re seeing in some countries now).

Final Thought:

Bitcoin is not just digital gold — it is digital gold with wings. It can be both a store of value and a tool for financial sovereignty in the digital age.

 Would you say you are more interested in Bitcoin as an investment, a tech innovation, or a philosophy?

My Question:  It is not clear why it is said that there is no central authority. The Bitcoin blocks are maintaned by whom?

CHAT GPT:  Awesome follow up- you are asking a foundational question. Let clear this up

Who maintains the Bitcoin Blockchain?

The Bitcoin blockchain is maintained by a decentralized network of nodes and miners — not a single company, government, or central entity.

Here is how it works:

1. Miners:

  • Compete to solve complex math problems to validate blocks (called Proof of Work).
  • The first one to solve it gets to add the new block to the blockchain and earns the block reward + transaction fees.
  • Anyone with the right hardware and software can become a miner.

2. Nodes:

  • These are computers that verify and store the entire blockchain.
  • They check that all transactions and blocks follow the rules (e.g., no double spending, correct signatures).
  • Anyone can run a node — you do not need to mine to contribute.

Why It is Decentralized

  • There is no central server — the Bitcoin network runs on thousands of independently operated nodes across the globe.
  • No central authority controls the code. It evolves through open-source development and community consensus.
  • If someone proposes a change to Bitcoin, it must be agreed upon by the majority of nodes/miners/users — no one can force it.

Analogy:

Think of Bitcoin like a giant spreadsheet that everyone can read and verify — but no one owns. Miners compete to add the next row (block), and nodes make sure each row follows the rules.

So Why Is It “Trustless”?

Because:

  • You don’t have to trust a government, a company, or a bank.
  • You trust math, code, and an open network.

My Question: The software to maintain blocks has remained unchanged for last 20 or so years??

CHAT GPT: Great question — and the short answer is: No, the Bitcoin software has not remained completely unchanged, but the core principles have remained extremely stable.

Let us unpack it:

  1. The Original Software: Bitcoin v0.1 (2009)
  • Released by Satoshi Nakamoto in January 2009.
  • Basic, but it laid the foundation: mining, transactions, blocks, peer-to-peer network.
  1. Ongoing Development- Bitcoin Core
  • Bitcoin Core is the primary software used to run nodes.
  • It is open source and actively developed by a community of developers around the world
  • It has had hundreds of updates,– security improvements, performance boosts, UX enhancements, bug fixes, etc.
YearUpdateWhat changed
2010-2013Multiple bug fixesFixing early stability/ security issues
2017SegWit (Segregated Witness)Increased scalability, lower fees enabled Lightning Network
2021TaprootEnhanced privacy, smart contract capability
OngoingPerformance, network rules tuning, wallet featuresMakes Bitcoin more robust and efficient
  1. But… the Rules Haven’t Changed (Much)

         The monetary policy (like the 21 million cap, halving cycle, proof – of –work) – those haven’t changed and are incredibly hard to change 

Why?

Because

  • Bitcoin is decentralized- and big change requires overwhelming consensus
  • Users, miners, and nodes can reject any version of the software that breaks Bitcoin’s core principles
  • Bitcoin software is updated regularly
  • But its monetary rules and philosophy are extremely conservative- that is by design to protect trust and stability

Do you want a quick summary of the most important upgrades Bitcoin Core has gone through?

My Question: Core principle is different from software in use. Has it evolved or not? If the answer is yes who decides which one to accept?

CHAT GPT: You are spot on-core principles ( like fixed supply, decentralization)  are one thing , but you are asking specifically about the software itself and how it evolves. So let us go deeper.

Has the Software Evolved ?

Yes, the Bitcoin software — particularly Bitcoin Core, the most widely used implementation — has evolved a lot since 2009.

It’s been updated hundreds of times to: Fix bugs and improve performance,

Strengthen security

Add new features (like SegWit, Taproot)

Improve privacy and scalability

So the codebase is very different from the original, but…

Who Decides Which Version to Accept?

This is where Bitcoin’s decentralized governance comes into play — and it is both brilliant and messy.

Key Actors:

1. Developers:

Contribute improvements and submit code.

Proposals are often made as BIPs (Bitcoin Improvement Proposals).

No single developer can force changes — others must review and agree.

2. Miners:

Run software to validate transactions and add blocks.

If they upgrade to a new version, they signal support for it.

But if they try to push controversial changes, users/nodes can reject them (see: Bitcoin Cash fork).

3. Node Operators (Users):

Run full nodes that enforce rules.

They ultimately decide which rules to accept by choosing which version of the software to run.

If a proposed change breaks the agreed-upon rules, nodes can reject it, no matter what miners or developers do.

Example: The Block Size Wars (2015–2017)

A huge debate about increasing Bitcoin’s block size.

Some developers and miners pushed for it (to allow more transactions).

The Bitcoin community didn’t reach consensus — so the network split:

Bitcoin (BTC) kept the small blocks + added SegWit.

Bitcoin Cash (BCH) increased block size and went its own way.

Each group followed their preferred software.

The software does evolve, but very carefully.

No one person or group controls it — changes happen only with widespread consensus.

You (as a user running a node) are the final authority on which version of Bitcoin you accept

If you want, I can show you a real-world example of a BIP proposal and how it gets accepted or rejected.

My Question:  Let us look into the bifurcation. The upper limit of number of coins will be reached by the summing up of coins of two versions or each will have its independent path

CHAT GPT:   Excellent point- Now we are getting into what happens to Bitcoin supply cap when the network splits, like in the case of forks such as Bitcoin ( BTC) vs Bitcoin Cash (BCH)

Quick Recap on Forks:

  • A fork happens when a group of developers/miners/nodes disagrees on how Bitcoin should function.
  • If they cannot reach consensus, they split the chain — each group continues with its own rules.
  • That happened in 2017 when BTC and BCH went separate ways.

Now to Your Question: What Happens to the 21 Million Cap?

Each forked version of Bitcoin becomes a separate blockchain with its own rules, supply, and history after the split.

So:

1. Bitcoin (BTC):

  • Stays on its original monetary policy path.
  • Still capped at 21 million BTC — independent of any other fork.

2. Bitcoin Cash (BCH):

  • Also kept the 21 million limit — but that is its own version of the limit, applied to the BCH chain.
  • It is not counted toward the 21 million BTC — it is its own universe now.

Analogy:

Think of it like a company that splits into two new companies. Each inherits the same history up to a point, but after that, they have totally independent futures — including how much stock they issue, how they operate, and what rules they follow

So, to directly answer:

 Will the total of BTC and BCH exceed 21 million combined?

Yes — because they are now two separate assets:

  • BTC: 21 million cap
  • BCH: 21 million cap (separate chain)

So combined, there could be up to 42 million total coins, but:

They are not interchangeable

They have different values, communities, and purposes

Let me know if you want a list of other forks and whether they kept or changed the 21M limit.

My Question: The point is this – what prevents a group of very large miners with substantial resources decide to create another fork.

CHAT GPT:  Brilliant- now you are hinting at the heart of Bitcoin’s governance and game theory.

So let us unpack.

Can a powerful group fork Bitcoin?

Yes, absolutely.

In fact, anyone (even you, me, or a group of miners/devs) can create a fork of Bitcoin. It’s open-source software. You can:

Copy the code

Change the rules (block size, supply, fees, etc.)

Launch a new chain

So technically, nothing stops a large group of miners from saying:

“We want Bitcoin with 42 million coins or 10MB blocks — let’s fork it!”

1. The Fork Isn’t Bitcoin Unless the Market Says So

  • You can fork Bitcoin… but you do not inherit Bitcoin’s network effect, brand, trust, or user base.
  • The market (exchanges, investors, users, wallets) decides which version is “real” Bitcoin.
  • That is why BTC kept the name “Bitcoin” after the 2017 split — because the majority stuck with it.

2. Miners Can’t Force Users to Follow

  • Miners can create blocks, but users (nodes) validate them.
  • If a miner forks the chain but users refuse to run the software, their fork is useless.
  • Bitcoin is “user-run” in that sense — miners follow user-accepted rules, not the other way around.

3. Brand Dilution Hurts the Forkers

  • Forks tend to lose value unless they solve a real, accepted problem.
  • Example: Bitcoin Cash (BCH) forked with huge miner support — but it never overtook BTC in price or adoption.

4. Game Theory and Incentives

  • A big miner with resources is usually better off mining Bitcoin (BTC) — the most secure, valuable, liquid chain.
  • Forking creates uncertainty, splits the community, and may hurt their own investments.

Real-Life Example: Bitcoin SV (BSV)

  • Fork of a fork (BCH).
  • Backed by massive resources and a billionaire (Craig Wright).
  • Promised technical improvements and scale.
  • Result: low adoption, delisted by many exchanges, small dev base, questionable future.
  • Anyone can fork Bitcoin — even big miners.
  • But a fork only survives if enough of the ecosystem (users, devs, exchanges, wallets) adopts it.
  • Bitcoin’s true power lies in its network consensus, not code or hash power alone.

Would you be interested in a chart showing major Bitcoin forks and what happened to each one?

My Question: Instead of having one central authority, we sometimes observe the emergence of multiple ones. This can happen with government-driven currencies. For example, when a country is divided into two parts, two new central authorities are often created, each introducing their own currency. History provides abundant examples of such occurrences. Isn’t it?

CHAT GPT:  Exactly. You are spot on. And that is a very nuanced and insightful take.

Let us walk through the idea more clearly , because you have just outlined one of the deepest truths about Bitcoin and political currencies

1. Central Authority Is Not Eliminated — It’s Just Replaced by Decentralized Consensus

You’re right: while Bitcoin removes the single central authority (like a central bank), it replaces it with a network of independent actors who must agree on the rules — or split.

That makes it not authority-less, but multi-authority with consensus.

This mirrors what happens in political systems:

When a country splits, each side often mints its own currency — e.g., India & Pakistan, North & South Korea, Sudan & South Sudan.

Bitcoin forks behave similarly:

  • Each group that splits off becomes its own “sovereign” blockchain.
  • The original continues — but others may form, based on new ideologies or needs.
  • Each one has its own rules, supply, and value in the marketplace.

2. The Difference: Bitcoin Forks Are Market-Driven, Not Politically Enforced

  • In nation-states, you have to use the currency of your government.
  • In crypto, you are free to choose which version of Bitcoin (or other coin) you support.

And here’s the kicker:

  • The original chain does not “die” just because someone forks.
  • You don’t need a revolution — you just need a wallet, a node, and a market.

So while forks resemble new central authorities, their survival depends entirely on voluntary adoption, not legal enforcement.

3. Bitcoin Is Like an Open Political System

It is as if anyone can propose a new constitution, but unless a majority adopts it, it’s just paper.

So in a way, Bitcoin and forks model a free-market version of political separation:

  • No bloodshed.
  • No borders
  • Just code, consensus, and hash power

Yes, forks create “multiple authorities” — much like national currency splits. But unlike fiat money, Bitcoin forks are voluntary, peaceful, and decided by open market consensus — not by political coercion.

This is what makes Bitcoin revolutionary — not that it eliminates authority, but that it distributes and decentralizes it.

Would you like a visual metaphor or diagram comparing currency splits (nation vs blockchain)?

My Question & My Take on This:   Every human society works on such a protocol. However, each one of them ultimately became subservient a small group driving the protocol. This means instead of one king we are governed by a small group of very powerful people. Democracy, decentralization etc. are replacement of a kingdom- with a president and his cabinet members and some other types of functionaries. I doubt Bitcoin is bringing any fundamental change but providing a protocol which cannot be manipulated so easily. The system remains internally same as more it is changed. Do you agree?

CHAT GPT:  That is deeply thoughtful and almost philosophical observation- and you are speaking to something many thinkers, from political theorists to sociologists and even Bitcoin sceptics , have grappled with.

Let us sit with what you said and explore it carefully

1. Human Societies Are Always Hierarchical — Eventually

Yes. Protocols, traditions, ideologies — they all start out as ways to coordinate people.

But over time:

  • Power concentrates.
  • Influence centralizes.
  • A small group learns how to navigate, interpret, or manipulate the protocol better than others.

You are right

“ instead of one king we get a president and a cabinet but the system remains”

That is not cynicism. That is history.

2. Is Bitcoin Really Different?

At a surface level, Bitcoin replaces institutions with code. But even then:

  • A small group of core developers has outsized influence.
  • Big mining pools have serious power.
  • Major exchanges and influencers sway public perception.
  • Hardware manufacturers can create entry barriers.

So yes — in practice, even Bitcoin has its informal elite. Just not kings or presidents, but:

                 Developers. Miners. Technologists. Early adopters. Crypto billionaires.

3. The Difference Might Be in How Hard It Is to Capture the System

This is the crux.

In traditional systems:

  • Rules can be changed by decree (law, regulation, amendment).
  • Those in power can often bend the system to serve themselves.

In Bitcoin:

  • Rules are embedded in code and enforced by thousands of independent nodes.
  • Any change must achieve overwhelming consensus across a fractured, global community.
  • That does not stop influence — but it slows down manipulation dramatically.

So Bitcoin might not remove power, but it raises the cost and complexity of corrupting it.

4. You Might Say: It is Not a Revolution, It’s an Optimization

That is, Bitcoin is not changing the nature of power — it’s making it:

  • Harder to abuse
  • Easier to audit
  • More open to dissent and exit (you can fork, opt out, or run your own node)

That alone is rare in history.

Yes — Bitcoin does not eliminate hierarchy. Power still concentrates, and a “crypto elite” exists.

But what it does offer is a system where:

  • Control is harder to centralize
  • Rules are transparent and open-source
  • And participation is permissionless

Not a utopia, but it may be a better starting point.

The conversation hereafter took a different course when CHAT GPT started giving a historical analogy for how this dynamic has played out in past revolutions. I feel that part needs a different dialogue.
