What Is Bitcoin? A Beginner’s Guide to Bitcoin Trading

Bitcoin is a decentralized digital currency that runs on a public network of computers rather than through a bank or a government. It was launched in January 2009 by an anonymous developer using the name Satoshi Nakamoto, its supply is capped at 21 million coins, and every transaction is recorded on a shared ledger called the blockchain. That is the short answer. The rest of this guide covers how Bitcoin actually works, what it is worth today, why its price moves the way it does, the different ways you can trade or own it, what each route costs, and the risks that catch new traders out.

Key takeaways

• Bitcoin’s supply is capped at 21 million coins and roughly 20.08 million have already been mined, which is about 95.6% of the total that will ever exist.
• The block reward is currently 3.125 BTC. The next halving is projected for around 18 April 2028, at block 1,050,000.
• Bitcoin traded near USD 78,900 on 3 September 2026, roughly 37% below its record high of USD 126,080 set on 6 October 2025. Volatility works in both directions.
• Owning Bitcoin and trading Bitcoin are two different activities. Spot buying gives you the asset. A CFD trading position gives you exposure to the price, with leverage, in both directions, and no wallet to manage.
• Access depends on where you live. Crypto derivatives are available to retail clients in many markets but are banned for retail consumers in the United Kingdom, and rules differ again across the EU, the UAE and South Africa.

What is Bitcoin?

Bitcoin is a peer-to-peer digital currency that lets people send value directly to one another over the internet without a bank, a payment processor or a central authority in the middle. It is the first and largest cryptocurrency by market value, and the ticker used by most brokers and exchanges is BTC.

The idea was published in a nine-page white paper in October 2008 under the name Satoshi Nakamoto. The first block, known as the genesis block, was mined on 3 January 2009. Nobody has ever confirmed who Satoshi Nakamoto is, and the coins associated with those earliest blocks have never moved.

Three things separate Bitcoin from the money in your bank account. It is not issued by any state. Its total supply is fixed in code rather than set by policy. And its transaction history is public, so anyone can audit it.

Key features of Bitcoin

How does Bitcoin work?

Bitcoin works by recording every transaction on a blockchain, a shared database copied across thousands of independent computers. Miners compete to add each new block of transactions by solving a computational puzzle, and the rest of the network checks their work. Once a block is added, reversing it becomes progressively harder.

Here is the sequence when you send bitcoin:

1. You create a transaction. Your wallet signs it with a private key, which proves you control the coins without revealing the key itself.
2. The transaction is broadcast. It travels to nodes across the network and sits in a waiting area called the mempool.
3. A miner includes it in a block. Miners select transactions, usually favouring those paying higher fees, and race to find a valid solution under a system called proof of work.
4. The network confirms the block. Other nodes verify it independently. A new block is found roughly every ten minutes on average.
5. Confirmations accumulate. Each subsequent block makes the transaction harder to reverse. Many exchanges treat three to six confirmations as settled.

The security behind that process is measurable. Network hashrate, the total computing power pointed at Bitcoin, sat close to 1 zettahash per second through August 2026, with mining difficulty around 127 trillion. Rewriting recent history would mean out-computing that entire network.

What is Bitcoin mining?

Bitcoin mining is the process of validating transactions and creating new bitcoin. Miners spend electricity running specialised hardware to find a number that produces a valid block hash. The first to succeed adds the block and collects the block subsidy plus transaction fees. Mining is what secures the network and what releases new supply into circulation.

What gives Bitcoin its value?

Bitcoin has value for the same reasons any traded asset does. Supply is limited and verifiable, demand comes from millions of participants, and a large, liquid market exists where the two meet. It is not backed by a government or a cash flow, so its price rests on what participants are prepared to pay.

Four factors do most of the work:

• Verifiable scarcity. The 21 million cap is enforced by software running on every node, not by a promise. Anyone can check the current supply themselves.
• Network effect. Bitcoin has the deepest liquidity, the widest exchange listings and the most institutional infrastructure of any digital asset.
• Security budget. The cost of the hardware and electricity securing the network is a real economic barrier to attacking it.
• Adoption channels. Spot exchange-traded funds, regulated brokers, custodians and payment networks all now provide routes in that did not exist a decade ago.

Against that, Bitcoin produces no dividend, no coupon and no earnings. That is the core of the digital gold argument and the core of the case against it, depending on which side you take.

Bitcoin supply and the halving explained

The Bitcoin halving is a programmed event that cuts the reward paid to miners in half roughly every four years, or every 210,000 blocks. It is the mechanism that slows new supply until issuance stops altogether at 21 million coins, expected some time around 2140.

Roughly 20.08 million of the 21 million coins have been mined, leaving under a million still to be issued over more than a century. Traders watch halvings closely because each one reduces the flow of new coins reaching the market, though past cycles are not a reliable guide to future price behaviour, and the 2026 drawdown is a reminder of that.

Where Bitcoin stands in 2026

Bitcoin entered 2026 well below the record it set in October 2025 and has spent the year trading in a wide, headline-driven range. Three forces have dominated.

Macro policy.

Bitcoin now trades much like a long-duration risk asset. Expectations of tighter policy and firmer inflation have weighed on it through 2026, alongside geopolitical flashpoints that lifted oil and rate-hike expectations at the same time.

Institutional flows.

US spot Bitcoin exchange-traded funds have become a visible swing factor. A record 13-day run of outflows totalling about USD 4.4 billion ran from mid-May into early June 2026, and total ETF holdings fell to about 1.277 million BTC, worth roughly USD 80.4 billion, before the streak broke on 5 June.

Regulation.

Rules kept moving. The GENIUS Act, the US stablecoin law, was enacted on 18 July 2025. The Digital Asset Market Clarity Act passed the House in July 2025 but was still awaiting a Senate vote as of early September 2026. In the EU, the MiCA framework became fully applicable on 30 December 2024, with national transitional periods running to 1 July 2026. In the UK, the Financial Conduct Authority opened retail access to crypto exchange-traded notes on 8 October 2025 while keeping its ban on retail access to cryptoasset derivatives in place.

The practical takeaway for a beginner is simple. Bitcoin is no longer a fringe market, but it is still a volatile one, and where you live determines what you are allowed to trade.

Why people trade Bitcoin

People trade Bitcoin for movement, access and hours. It is one of the few markets that trades continuously, it moves far more than most currency pairs on an average day, and the minimum position size at a broker is small enough to start with modest capital.

• Volatility. Daily ranges are wide by the standards of forex or indices. That creates opportunity and equally creates losses, which is why volatility trading and position control matter more here than almost anywhere else.
• Round-the-clock access. Crypto markets do not close for the weekend, so positions can be opened or managed at any hour.
• Two-way exposure. Through derivatives you can take a short position as easily as a long one, which is not the case when you simply buy and hold coins.
• Low entry point. Bitcoin divides into 100 million satoshis, and broker minimum trade sizes are small, so you do not need to buy a whole coin.
• Diversification. Bitcoin’s correlation with equities and gold shifts over time, which is why it appears in discussions about a diversified portfolio and why the Bitcoin versus gold debate keeps running.

Sentiment tools such as the Bitcoin Fear and Greed Index are widely followed for the same reason. Crowd positioning tends to swing hard in this market.

Ways to trade or own Bitcoin

There are five main routes into Bitcoin, and they differ on one question above all: do you end up owning the coin, or exposure to its price?

Spot Bitcoin versus Bitcoin CFDs

This is the comparison most beginners actually need.

A CFD, or contract for difference, settles the difference in price between the point you open a position and the point you close it. Because it is a derivative, you never take delivery of bitcoin and never manage crypto wallet security yourself. That removes one category of risk and adds another, since CFD leverage increases both the gain and the loss on the same price move.

At VT Markets, Bitcoin is available as BTCUSD alongside more than 60 crypto pairs including Ethereum and selected altcoins, plus BTCXAU and ETHXAU synthetic CFDs that price crypto directly against gold. Leverage, product availability and account terms vary by entity and by country of residence.

How to start Bitcoin trading in six steps

1. Decide what you are actually doing. Buying and holding coins for years is investing. Taking positions on the price over days or weeks is trading. The two need different accounts, different tools and different mindsets.
2. Choose a regulated provider. Check which legal entity you would be contracting with, what protections apply there and whether your country is served. VT Markets sets out its licences on the VT Markets regulation page.
3. Open and verify the account. Expect identity verification under standard know-your-customer rules. Have a proof of identity and proof of address ready.
4. Practise before you fund. A demo account lets you place BTCUSD trades in live market conditions with no capital at risk. Use it long enough to see a losing streak, not just a winning one.
5. Fund and size the first position properly. Work out your maximum loss per trade before you work out your target. Many experienced traders risk a small fixed percentage of account equity per position, and position sizing is the calculation that turns that rule into a lot size.
6. Place the trade with a stop already set. Decide your exit before you enter. Our guide to stop loss and take profit covers how to place them at levels the market can respect rather than at round numbers.

Bitcoin trading strategies for beginners

No strategy removes risk. What a strategy does is make your decisions repeatable, so you can tell a bad process from bad luck.

If you are still building chart-reading skills, start with technical analysis fundamentals before layering indicators, and read our roundup of cryptocurrency trading strategies. Traders who prefer to learn by watching sometimes begin with copy trading, which carries its own risks and still requires you to choose the provider.

What Bitcoin trading actually costs

Costs are where beginners lose money quietly. With Bitcoin CFDs there are three, and they compound.

• Spread. The gap between the buy and sell price. Crypto spreads are usually wider than major forex pairs and widen further in thin liquidity, at weekends and around major news.
• Commission. Charged on some account types instead of a wider spread. Compare the total of spread plus commission rather than either figure alone.
• Overnight financing. A swap charge or credit applied to positions held past the daily cut-off. Over a multi-week hold it can outweigh the spread entirely.

With spot buying, the equivalent costs are the exchange trading fee, the withdrawal fee and, if you self-custody, the network fee to move coins. Neither route is free, and the cheaper one depends on how long you intend to hold.

Risks of Bitcoin trading

Bitcoin is one of the most volatile liquid markets available to retail traders. Its record high of USD 126,080 in October 2025 and the roughly 37% drawdown that followed by September 2026 are the same asset, thirteen months apart. Understand these risks before funding an account.

A useful discipline: decide the maximum you are prepared to lose on a trade before you decide what you hope to make on it. Our roundup of common crypto trading mistakes covers the patterns that repeat most often.

Risk warning. Trading CFDs on cryptocurrencies carries a high level of risk and can result in the loss of all invested capital. It is not suitable for every investor. Nothing here is investment advice or a recommendation to trade any specific instrument.

Bitcoin compared with gold, stocks and forex

For a fuller comparison of where each fits, see forex, stocks and crypto and our analysis of Bitcoin versus gold.

Is Bitcoin legal? Regulation by region in 2026

Bitcoin itself is legal to own in most major economies. What varies is which Bitcoin products you can access, and under whose supervision.

Always confirm the position with your local financial authority before trading. Availability, leverage and investor protections attach to a legal entity, not to a brand name.

Common beginner mistakes to avoid

• Sizing the first position as though the plan will work, rather than as though it will not.
• Using maximum available leverage because it is offered.
• Trading without a stop, then widening it when price approaches.
• Confusing a spot purchase with a leveraged CFD position and expecting them to behave the same way.
• Holding a leveraged position over the weekend without allowing for gaps.
• Chasing an altcoin season narrative into low-liquidity coins after the move has run.
• Ignoring overnight financing on positions held for weeks.
• Treating a four-year halving pattern as a schedule rather than a historical observation.
