How to Buy Cryptocurrency: A Step-by-Step Beginner’s Guide

You might have followed the headlines, watched prices move, and decided it is time to buy your first Bitcoin, Ethereum, or another cryptocurrency. At the same time, you may think charts, acronyms, and technical language can be a lot to take in.

Buying cryptocurrency has become more accessible, but it is not risk free or “easy money”. This guide explains how buying works in practice, how to secure your account, and what you should consider before you press the “buy” button.

Understanding the Marketplace

Before you buy, it helps to understand what you are using. Most beginners start on a crypto exchange, or what is known as a spot market.

A spot market is a marketplace where assets are bought and sold for immediate delivery at the current price. When you buy crypto on a spot market such as CoinJar, you are exchanging government-issued money (known as fiat currency, for example GBP) for a cryptocurrency at the live market rate.

Once the transaction is complete, you hold the digital asset in your account and can keep it there, or transfer it to a private wallet. However, the value of that asset can go down as well as up, sometimes very quickly.

How it works in practice

On most platforms, buying cryptocurrency follows four main steps: registration, verification, deposit, and trade. These steps are fairly standard, although the detail and timing can vary by provider and by country.

1. Registration

To start, download the CoinJar app. After this is done, you will need to create an account.

On CoinJar, this means providing a valid email address, creating a strong password, and accepting the relevant terms. Because your account may hold money and crypto, you should use a unique password that you do not reuse elsewhere and that is difficult for others to guess.

Even at this early stage, you should think about security. A weak password or shared login can put your account at risk.

2. Identity Verification (KYC)

After signing up, you usually cannot trade straight away. You first need to complete a process called Know Your Customer, or KYC.

This is a legal and regulatory requirement firms and reputable exchanges. It helps confirm that you are who you say you are and supports checks designed to reduce fraud, money laundering, and other financial crime.

To verify your account, you will normally need to upload:

• A government-issued photo ID (for example a passport or driving licence).
• A selfie or short video to confirm that the ID belongs to you.

This step can feel like a hurdle, but it is an important safeguard. If a platform does not ask for any verification and still allows large deposits or withdrawals, that can itself be a red flag.

When UK residents sign up for a CoinJar account, they're subject to a mandatory 24-hour cooling-off period that begins immediately upon account creation. All registered crypto exchanges will require this step.

Additionally, you must complete an appropriateness assessment in the form of a knowledge quiz that verifies your understanding of the risks involved in cryptoasset trading. Again this is a requirement of all registered crypto exchanges.

3. Depositing Funds

Once your identity has been verified, you can add money to your account.

On CoinJar, UK users can:

• Deposit GBP by bank transfer from a personal account in your own name.
• Use cards for purchases, and also Apple Pay or Google Pay.

Always check the fees, limits, and timeframes before you deposit. Bank transfers might take longer but can be cheaper. Card payments can be faster but may involve higher fees or cash advance charges from your card provider.

4. Placing the Trade

When funds have arrived and cleared, you can place a buy order.

In simple terms, you:

1. Go to the buy button in the middle left of the app home screen or the trade button at the bottom in the middle.
2. Select the cryptocurrency you want (for example Bitcoin).
3. Choose how much GBP you want to spend or how much crypto you want to buy.
4. Review the quoted price, any fees, and the total amount you will receive.
5. Confirm the transaction if you are comfortable with the details.

Your cash balance decreases and your crypto balance increases. This usually happens quickly, although the displayed value can still move at any time. You can press the “Portfolio” button to see your account.

Remember that buying crypto is a speculative investment. There is no guarantee that you will be able to sell later at a higher price, or even at the price you paid.

Keeping Your Assets Safe

Owning cryptocurrency comes with extra responsibility. Blockchain transactions are typically irreversible. If you make a mistake or send funds to the wrong place, you are unlikely to be able to get them back.

You should therefore treat account security as seriously as you would, or more seriously than, online banking.

Two-Factor Authentication (2FA)

As soon as your CoinJar account is set up, you should enable two-factor authentication, often using an authenticator app.

With 2FA, logging in or making key changes will require:

• Your email and password, and
• A time-limited code from your phone or another approved device.

This means that even if someone steals or guesses your password, they still should not be able to access your account without that second factor. While 2FA does not remove all risk, it makes many common attacks harder to carry out.

Account Recovery

One benefit of using a centralised exchange such as CoinJar is having some support if you lose access to your account.

In a “self-custody” set-up, you control your funds directly using private keys, often stored in a hardware wallet or written down as a recovery phrase. That gives you more control, but also more risk. If you lose those keys or your recovery phrase, you may lose access to your funds permanently and there is usually no way to reset or recover them.

With an exchange, your account details can often be recovered. If you forget your password or lose access to your 2FA device, you can contact CoinJar Support through official channels. You will likely need to go through further identity checks and provide documents again. Recovery is not instant and is not guaranteed, but you are less dependent on a single phrase or device.

Risks, Red Flags, and Security

Even if you follow all the steps correctly, investing in crypto involves significant risk. Prices can be unpredictable, technical issues can occur, and bad actors operate in the market.

You should only invest money you can afford to lose and you should be prepared for the possibility of losing your entire investment.

Recovery Scams

If something goes wrong, you may feel pressured to act quickly. This is when scammers often appear.

Be extremely wary of any person or service, especially on social media or messaging apps, that claims they can “recover” stolen or lost crypto for a fee. Once a valid blockchain transaction has been confirmed, it usually cannot be reversed. Neither CoinJar nor any third party can “hack” the blockchain to retrieve or rewrite transactions.

So-called “recovery agents” who promise to get your funds back are usually attempting a second scam, often targeting people who have already been victims. If you are unsure, speak only to your exchange’s official support channels and do not share your private keys, passwords, or 2FA codes with anyone.

Summary

Buying cryptocurrency using a platform such as CoinJar follows a straightforward structure: Create an account, verify your identity, deposit funds, then place a trade. The process itself can be simple to follow, but the investment risks are significant and should not be underestimated.

Use strong security practices, including unique passwords and 2FA. Keep careful records for your own tracking and for potential tax reporting. Most importantly, treat crypto as a high-risk investment, stay cautious of anything that sounds too good to be true, and only commit money you can afford to lose.
