Learning the friendly way

While you’ve likely come across the world of cryptocurrencies, you most probably have stumbled upon the term “blockchain”. But what is the blockchain solution? Blockchain is not only the revolutionary technology behind cryptocurrencies, it also has a large use case outside of the cryptocurrency and even the finance sector.

In the decade since blockchain technologies and digital ledger technology came to light, a host of blockchain networks have been created, most with their own digital currency. As the industry has grown and new blockchain networks have emerged, innovation in the space has increased significantly.

From the Ethereum blockchain providing a platform on which developers can create digital assets and smart contracts to corporate organizations implementing a private blockchain in order to streamline their services, the technology is propelling mankind forward in ways not witnessed in decades.

The blockchain solution provides much more than just digital assets, and industries far beyond just the payment processing ones are catching on. With traditional business networks incorporating the technology, the world of permissioned blockchain is igniting.

What is Blockchain?

Blockchain is a decentralized, transparent, immutable technology that keeps a public record of all information entered. Designed to record and distribute information, not to be edited. Also referred to as a public ledger, a blockchain keeps a record of all information ever inputted and stores it chronologically in blocks.

These blocks are linked to each other through a hashing system, which ensures that no one can ever tamper with the previous records, or try to manipulate the information on them. The “chain” of blocks make up the blockchain database.

The decentralized technology is not typically run by one entity, but rather from a variety of computers (also known as nodes) that make up the network, and work together to validate transactions and all information added to the blocks. Blockchain can be used in two forms, as a public blockchain or as private blockchain networks.

The public version allows anyone to view all information on the network, while the private reserves the information for members granted access.

The Advantages of Blockchain Technology

Powerful Technology

Invented in 2008 alongside Bitcoin by an anonymous entity Satoshi Nakamoto, blockchain is the technology that fueled the new way that money is transacted. Not only that, the technology offers incredible use cases far beyond the financial world. 

Fully Trusted, Fully Automated

One of the key features of blockchain is its ability to function without a central authority. The technology is designed to be maintained by various operating systems on the network, with full autonomy dispersed evenly. Information is stored on the blockchain in such a way that everyone can view it but no one can go back and tamper with it.

Powering Industries

While blockchain is the technology behind crypto, it also offers an incredible backbone to a diverse range of industries outside of this space. Companies like Nestle, Microsoft and Walmart are onboarding blockchain, proving to offer a strong and highly adaptable infrastructure to financial, property, and supply chain management entities. The number of blockchain companies is growing by the day.

The Core Benefits of a Blockchain Network

Decentralized

Blockchain networks are designed to be entirely decentralized meaning that there is no one central authority. The entire network is maintained by nodes (computers) around the world and no single entity has control. 

Immutable

Once the information has been added to a blockchain, no one can tamper, edit, or remove it. As information is verified and added to blocks, this solidifies its presence on the blockchain forever. 

Transparent

Blockchain offers a transparent view of all the activity that takes place on the network. This takes away the need for any checks or balances as all the information is available at any given time, in real-time.

What is the Difference Between a Public Blockchain and Private Blockchain?

When understanding what is blockchain, a common question is whether blockchain is secure. The answer is yes, blockchain is very secure.

Due to its decentralized nature, the technology requires a network of operators (computers) to verify and input all the information. As soon as one tries to input incorrect information or conduct illicit transactions, the network will recognize this and reject it immediately. 

The difference between a public and private blockchain is that public blockchain networks are open for anyone to see, while private blockchains are closed to an organization or a selected group of people.

Cryptocurrency networks are examples of public blockchain networks in that anyone can view all the transaction data. For a private blockchain, however, users will need special permission to access this information.

How is Blockchain Tamperproof?

Each block is made up of three things: the hash code of the previous block, the relevant information, and its own hash code.

When a new block is added, the new block will again have the hash of the previous block, the relevant information, and its own hash. This special sequence of hashes ensures that all blocks are stored chronologically, in a linear fashion, meaning that you cannot tamper with one block's information without tampering with every block after that.

Tampering with blocks would take an enormous amount of computing power and is largely considered impossible. Hence the security of using a digital asset or digital currency.

Blockchain Explained: How Does It Work

At its core, blockchain records and distributes information to a wide network of users that participate in verifying the information and maintaining the network. Let’s take a deeper look at Bitcoin transactions to further explain how blockchain works. 

If one user wanted to send a portion of Bitcoin to another user, they would require the user’s wallet address. Each wallet is made up of two codes, a public and private key, which enable the user to receive BTC (through the public key), as well as access BTC and conduct transactions (through the private key). The sender will then input the receiver’s wallet code and send the amount of Bitcoin they desire. 

This transaction will then enter a pool of transactions waiting to be verified by a miner on the network. The miner will ensure that the sender owns the amount they are sending, and verify the transaction along with a number of other transactions.

On the Bitcoin network, the size of one block is 1MB, which equates to roughly 3,200 transactions able to be stored in one block. When building a blockchain network, the size of the blocks can be increased or decreased to suit the use case. 

Once the transaction has been verified, the miner will record transactions processed and ensure they are added to the chain. The transaction ledger will then be distributed to the rest of the operators on the network. This new version will then override the older versions, and so on as more blocks are added.

Once the block is added to the blockchain and distributed, the funds will reflect in the receiver’s wallet. No need for a bank account or legal contracts, Bitcoin (and other digital currencies) operate entirely separately from traditional banking institutions and allow for the fast, efficient and cost-effective transaction of value.

Fraudulent transactions cannot take place as this will be flagged long before the block is added to the chain. Blockchain work in such a way that network participants can immediately flag ill actors and dismiss fraudulent financial transactions.

Understanding the Difference Between Blockchain and The Bitcoin Blockchain

The burning question: how does blockchain compare to Bitcoin. The answer is that it doesn’t, there are two separate, co-dependent technologies. Bitcoin, the cryptocurrency, is built on blockchain technology and requires it to function. There is no Bitcoin without blockchain technology.

Consider it the backbone of all cryptocurrencies. Blockchain technology, however, is an adaptable technology that can be used outside of the cryptocurrency industry. The technology can be used in any industry, provided that they require a transparent, immutable public ledger. 

One thing the two do have in common is that they were both introduced to the world at the same time. While the concept of blockchain technology was initially invented by researchers W. Scott Stornetta and Stuart Haber in 1991, it was referred to as distributed ledger technology (DLT) and was created purely to store office documents.

The anonymous entity Satoshi Nakamoto built on this and ultimately solved the double spending problem it was plagued with. In 2008, Nakamoto released both blockchain technology and Bitcoin in a whitepaper titled Bitcoin: A Peer-to-Peer Electronic Cash System.

The Bitcoin blockchain refers to the network, while blockchain technology refers to the technology as a whole.

In Conclusion

What is blockchain? Blockchain technology is the transparent, immutable storage of information. As mentioned earlier, this technology has use cases far outside of just the cryptocurrency and financial ecosystems.

Industries like renewable energy, supply chain management, and even farming sectors are now incorporating blockchain technology into their business systems, empowering them with a fully automated and safe means of storing records.

You've likely come across the term "ERC-20" in your crypto endeavours, with plenty of these token standards currently ranked in the top 10 (even top 100) cryptocurrencies. But what does ERC-20 actually mean, and what is a token standard? In this piece, we're uncovering everything you need to know about these popular crypto terms.

To start things off, ERC stands for Ethereum request for comment.

What is a token standard?

Let's start at the beginning. When Ethereum was created to provide developers with a platform on which to build decentralized apps (Dapps), the team incorporated several token standards. 

These token standards allow new projects to create, issue and deploy various functioning tokens on the blockchain. Each token standard is a smart contract that holds a set of particular "rules" that must be followed in order to be created.

In recent years a number of blockchain platforms that provide Dapp creation functionality have created their own token standards, however, for the sake of this article we are only looking at Ethereum.

The most popular token standards on Ethereum are the ERC-20, ERC-721, ERC-777, and ERC-1155 tokens. Each holds its own functionality and would be utilized depending on what the Dapp intends to use it for, i.e. will it be a transferable asset or be used to hold ownership rights. 

What is an ERC-20 token?

By far the most popular token standard utilized on the Ethereum network, the ERC-20 token is a fungible token that can be bought, sold and traded in the blockchain ecosystem. To date over 350,000 ERC-20 tokens have been created. 

Similar to the functioning of other cryptocurrencies like Bitcoin and Litecoin, ERC-20 tokens also hold value and are able to be bought and sold, however, they operate solely on the Ethereum blockchain. This means that all ERC-20 transactions conducted are executed on the Ethereum blockchain network.

The rules associated with this particular token ensure that it can function optimally on the Ethereum blockchain, and must be submitted to the community leadership for approval prior to its launch. While some rules are mandatory and others optional, the required ERC-20 rules are as follows:

• total supply: defines the total supply of the token
• balance of: indicates how many tokens are in a wallet address
• transfer To, Transfer From: must be able to be transferred from one user to another
• allowance: ensures that wallets have a sufficient amount before making a transaction
• approve: checks total supply against transactions

The optional elements are centred around the token's name, its ticker symbol and how many decimal places it would have %u200BFor instance, Ethereum's token name is Ether, its ticker symbol is ETH and it is divisible by up to 18 decimal places.

Examples of ERC-20 tokens are Augur (REP), Basic Attention Token (BAT), Maker (MKR), USD Coin (USDC) and OmiseGO (OMG).

Can you mine ERC-20 tokens?

ERC-20 tokens, unlike Ethereum and its native coins (ether), cannot be mined. That is, new tokens are 'minted' when a planned initial token offering (ICO) or security token offering (STO) event takes place. Usually, these events involve users sending ether to a smart contract address and in return receiving the newly minted ERC-20 token.

An ERC-20 token is technically a smart contract so it's possible for the developer team behind an ERC-20 token to issue new tokens at will. However, this isn't recommended because users would be less likely to trust these tokens if they could be minted at will. There must be a measure of scarcity in order for tokens to be valuable.

The pros & cons of ERC-20 tokens:

Some of the main benefits of ERC-20 tokens include: 

Fungible

Fungible ERC20 tokens are interchangeable, just like cash. Although the coins are technically distinct, they function in exactly the same way. You can trade one for another and they will be functionally equivalent, just like cash or gold.

Fungible tokens are fantastic, and there's a lot of value in the technical aspect. On a technical level, it's worth noting that fungible tokens don't add extra value to goods. They're typically beneficial in a variety of commercial scenarios.

Broad adoption

The popularity of ERC-20 tokens is quite apparent in the cryptocurrency industry. The number of exchanges, wallets, and smart contracts that already support newly-launched tokens has made it easy for new projects to integrate with them. There is plenty of developer support and documentation to go around.

Flexibility

The first thing to note about ERC-20 tokens is that they are highly flexible and may be used in a variety of circumstances and applications. This is due to the fact that these tokens are very customizable. They can be used in a lot of different scenarios such as Loyalty points programs, in-game currencies, or digital collectibles such as NFT's.

Some of the main cons of ERC-20 tokens include:

Mainstream

The popularity of ERC-20 tokens is also their greatest weakness. There are so many projects using the same standard that it's difficult to stand out from the crowd without differentiating your token in some way. Moreover, since they're essentially all the same on a technical level.

Fraud and Scams

It takes minimal effort to create a simple ERC-20 token, meaning that anyone could do it for good or bad purposes. As such you want to be careful with what you're investing in when considering blockchains projects because there are some Pyramid schemes masquerading as legitimate projects out there and trying to get unsuspecting investors involved in their scams. As a result, when looking at blockchain projects, you need to be cautious with what you invest in.

Other ERC Token Standards

While there is a large range of ERC tokens available, below we've outlined the most popular ones (excluding the ERC-20 one as it is listed above). 

ERC-721 

This token standard is for a non-fungible token (NFT) which gained huge popularity in the last year across the gaming and digital art worlds. These tokens represent ownership of something, and cannot be used interchangeably. 

ERC-777 

An evolution of the ERC-20 token, the ERC-777 provides more usability, particularly pertaining to its ability to mint or burn tokens. It also holds improved transaction privacy and an emergency recovery function. 

ERC-1155

This token standard allows for the creation of both utility tokens and non-fungible tokens. Making trading more efficient, the token standard allows for bundling of transactions which in turn saves costs.

The financial industry has seen significant growth within its digital sector due to the adaptation required during Covid-19. With the increased interest in digital payments has come the rise of virtual cards.

Shopping online and online purchases continue to break barriers that traditional financial institutions never predicted. While these institutions do allow users to do online shopping, there are still a lot of limitations and risks to be wary of. 

Every time you shop online, you risk your account number and details being stolen and used against you. Credit card companies have had to evolve, and one way they have done that is through the introduction of an actual account-linked virtual card.

How do virtual credit cards and debit cards work?

Virtual cards are stored on your mobile device and can be used to make contactless payments in store or online. A virtual card has its own unique card number, CVC, and expiration date. These virtual cards are simply a copy of your physical card, linked to your bank account, and stored on your application or phone. Think of it as an online account and card.

Virtual cards are very similar to an actual credit or debit card, with the main difference being that they only exist digitally, and can not be used to withdraw physical cash. Virtual credit cards provide the same features and mechanics as traditional credit and debit cards. 

A virtual credit card still has an expiry date and 16-digit account number, and CVV codes. They are connected to payment networks like Visa and Mastercard and are generally accepted by merchants who use physical card machines, similar to Apple and Google Pay. 

Your virtual card information and virtual credit card number are stored digitally, eliminating the risk of someone stealing your card and simply entering your details when shopping online. 

Virtual credit cards act as digital wallets, providing more advanced security and ease of online access. Virtual cards are created for one-time use or act as a temporary account number, but what are the benefits of a limited-use virtual card number? Let’s get into it.

Benefits of a virtual credit card

The first and foremost virtual credit card feature benefit that you can expect is an enhanced layer of security. To combat fraudulent activity, a data breach, and account information being stolen, virtual cards have randomly generated and disposable card numbers. This makes virtual cards one of the safest payment methods, eliminating physical and confirmed details, meaning your temporary information can not be stolen or lost. If your info is compromised, you can cancel it without having to create a new bank account or waiting for a new card in the mail.

Control and customization is an additional layer of benefits users can expect from using virtual credit cards. Users can customize how many virtual account numbers they want, set spending limits, choose their preferred currencies, and more. Similar to a normal debit card account, you can also create recurring payments with merchant details, as tailored to the amount, time, and so on.

Some virtual credit cards provide users with point-earning rewards or store credit when used. Credit card companies can also easily access your information to improve your credit score based on your recurring payments set up. 

Creating multiple virtual debit cards allows you to distribute, allocate, and track funds with ease. This means at the end of the day, you have more visibility of your funds going in and out and can create a dedicated virtual debit card for a specific area of your financial responsibilities.

Getting your virtual card number

Whether you are trying to manage your funds with your debit or credit cards accounts, a virtual card can make matters easier. All you need is a debit or credit card account, such as the one offered by Tap and you can create your unique virtual card at the click of a button. With some traditional banks you can even create multiple cards if you want, each with its own unique account number and expiration date. 

These digital wallets and accounts provide ease when you want to shop online, avoid physical wallet and card theft, as well as easier fund management. A virtual debit card is a big part of the future, as we move into the digital era.

Experience a whole new world of digital payments and money management from the safety of your mobile device. You should be able to use your virtual card at any merchant that accepts debit and credit card payments, or contactless transactions, such as Apple Pay or Google Pay. Create your virtual account number today and enjoy purchases online and in-store. The future of payments is here.

Got Bitcoin and wondering how to turn it into spendable money? You're not alone. Whether you're looking to realize your profits, pay for goods and services, or simply diversify your investment portfolio, cashing out Bitcoin can be a straightforward process with the right guidance.

This guide breaks down everything you need to know about converting your digital currency into cold, hard cash (or cold digital cash, if you prefer).

How to cash out Bitcoin

There are a few options available to you - all with varying degrees of accessibility and complexities. We’ll run through them below, see which one most resonates with your preferences.

1. Online exchanges 

Online exchanges are probably the simplest option here, depending on the platform. When selecting a cryptocurrency exchange to cash out your Bitcoin, consider factors like security measures, user reviews, trading volume, and withdrawal fees. Look for exchanges that offer a seamless user experience and prioritise the safety of your funds.

While crypto exchanges will charge a small fee, they also allow you to: 

• Sell Bitcoin directly
• Transfer money to your bank account
• Track your transactions easily

Using Tap as an example, the process would be to download the app, create an account, complete the quick identity verification process (<5 minutes) and then transfer your BTC to your unique BTC wallet.

To sell it, simply select Sell, confirm the transaction and choose which currency you would like to receive the funds in. These funds will then be deposited into the relevant wallet in the app, which you can use to pay bills, send to your fiat bank account, spend using your Tap card or withdraw from an ATM. 

Transaction costs: usually 0.5% - 1.5%

2. Bitcoin ATMs

Bitcoin ATMs are darted around countries (see here for specifics) and allow users to withdraw the local currency for Bitcoin. Note that this route is notorious for higher fees, so take note when confirming the transaction. 

The advantages of Bitcoin ATMs:

• Instantly converts Bitcoin to cash
• Get money right on the spot
• Available in many major cities

Transaction costs: 5% - 10%

3. Direct peer-to-peer selling

Kind of like selling something on Gumtree, but for Bitcoin. These websites connect you directly with buyers who want Bitcoin and have varying degrees of security and features. 

Be sure to use verified platforms with good reviews as scams can be rife. Some of these platforms offer escrow services, meaning that they hold the BTC until the payment clears, after which they release the funds. Look at options like LocalBitcoins.

Transaction costs: Varies

Steps to ensure security

Before cashing out Bitcoin, here are a few steps to take to ensure the safety of your funds:

• Use reputable platforms that are licensed and regulated.
• Use strong passwords and enable two-factor authentication for added security.
• Regularly update your wallet/app software to protect against potential vulnerabilities.
• Avoid sharing your sensitive information or private keys with anyone to prevent unauthorised access.
• Consider diversifying your funds across multiple wallets for added protection. 

Tax implications of cashing out Bitcoin

When you sell Bitcoin for cash in the UK, it’s important to understand the potential tax implications. HMRC treats cryptocurrency transactions as taxable events, meaning you may need to report and pay Capital Gains Tax on any profits from the sale.

Consulting a tax professional or accountant can help you understand your obligations and navigate the often complex waters of cryptocurrency taxation. They can ensure you comply with current UK tax laws and provide guidance specific to your situation.

It’s also very important to keep an accurate record of all your crypto transactions. Make sure to document the date of purchase, the sale price, and any associated fees, as these records will make it easier to calculate and report your gains or losses when filing your tax return. (Side note: you can download your statements directly from the Tap app). 

For more information, explore HMRC's guidelines on cryptocurrency taxation. Staying informed and organised will help you manage your tax responsibilities smoothly and avoid potential penalties.

Verification requirements

When cashing out Bitcoin on an exchange, verifying your identity is an important step to ensure the security of your transaction and compliance with regulations. If a platform doesn’t ask for this verification: red flag. 

Overview of the verification process

Exchanges need to complete this verification step to prevent fraud and follow legal requirements. You’ll typically need to provide:

• A valid ID for identity verification
• Proof of address, such as a utility bill
• Sometimes, a selfie for facial recognition

The specific requirements can vary based on the exchange and the amount of Bitcoin you’re selling.

Tips for a smooth verification process

• Have all your documents ready before starting to avoid delays.
• Double-check the accuracy of the information you provide to prevent verification issues.
• Follow the exchange’s instructions carefully to ensure the process is quick and secure.

Security considerations

When submitting personal information, always use a trusted exchange with a strong reputation for security. Look for platforms known for protecting user data to reduce the risk of breaches.

Understanding fees when cashing out Bitcoin

Cashing out Bitcoin usually comes with some costs, so it’s good to know what to expect.

Exchange Fees

Most crypto exchanges charge a trading fee when you sell Bitcoin. The fee varies depending on the exchange and the size of your transaction.

Withdrawal Fees

If you transfer your funds to a bank account or payment method, the exchange might charge a withdrawal fee. These fees can be higher for larger transactions.

Network Fees

Bitcoin transactions also include network fees (or mining fees), which go to miners for verifying and processing your transaction on the blockchain.

To reduce fees, look for exchanges with low rates, choose slower transaction speeds to save on network fees, and compare withdrawal options to find the cheapest one.

Timing considerations traders might pay attention to

Timing can play a big role in deciding when to sell your Bitcoin. Here are some key factors traders often look out for:

Market conditions

Traders recommend staying updated on crypto news and keeping an eye on price trends and market conditions.

Withdrawal limits

Traders advise knowing the withdrawal limits of the exchange before completing their cash out so as to plan their cash-out strategy and avoid delays.

Funds transfer time

Traders plan ahead, knowing that it can take a few business days for funds to transfer after selling Bitcoin (depending on which avenue you took) allows them to manage their finances more efficiently.

Other potential roadblocks

When cashing out Bitcoin, keep an eye out for potential roadblocks, like minimum withdrawal amounts, which could affect how much you can withdraw at once. 

Be prepared for account verification requirements, as exchanges often need you to verify your identity before processing transactions. On some platforms this can take days - not ideal if you’re trying to take advantage of price surges. 

You might also have to deal with geographic restrictions that limit access to certain exchanges based on your location. Be sure to check this before signing up with a platform.

Conclusion

Here we’ve covered the essentials of cashing out Bitcoin, from selecting an exchange to understanding taxes. If you’re new to cryptocurrency, take the time to learn about the process before selling, and remember that what works for one person might not work for another. Being prepared will help you make better decisions and avoid mistakes.

As Bitcoin has grown from a niche investment to a widely accepted payment method, it is now accepted by millions of merchants around the world. This guide will cover everything you need to know about using Bitcoin for payments, from simple transactions to more advanced tips. And no, you don’t need to be a tech whizz to figure this out. 

Getting started with Bitcoin payments

Before using Bitcoin, we’d recommend that you first understand how the decentralised payment system works. A great place to start is our guide on What Bitcoin Is. 

Once you’ve got a grip on the basics and you’re ready to dive into payments, the first step will be setting up a Bitcoin wallet, which will serve as your digital tool for sending and receiving cryptocurrency.

How to set up your Bitcoin wallet

Your Bitcoin wallet is your personal gateway to the Bitcoin network. With a range of options available, here are some popular wallet options:

• Hardware wallets (like Ledger or Trezor) for maximum security
• Mobile wallets (such as Tap) for convenience
• Desktop wallets for detailed control
• Web wallets for easy access

It’s a good idea to choose a type of wallet that balances your security needs with your accessibility requirements - each person will have their own preference. 

Different methods of paying with Bitcoin

Directly to the merchant 

Many businesses now accept Bitcoin directly through their online or PoS payment systems. The process typically involves:

1. Selecting Bitcoin as your payment method
2. Scanning a QR code with your wallet
3. Confirming the transaction amount
4. Waiting for network confirmation

Through payment processors

Payment processors like Tap help bridge the gap between Bitcoin and traditional payment systems. These services often provide:

• Instant conversion to fiat currency for merchants
• Lower transaction fees compared to credit cards
• Integration with existing point-of-sale systems
• Customer protection features

(If you’re a business looking to leverage crypto in your operations, see our range of business services here). 

Peer-to-peer transactions

For direct person-to-person payments, Bitcoin offers several advantages:

• No intermediary required
• Lower fees than traditional wire transfers
• Cross-border transactions without currency conversion
• Immediate settlement options

With Tap, you can send funds directly to other Tap users for free. Users will still be liable for the Bitcoin transaction fee as this is outside of Tap’s control.

Where to spend Bitcoin

As the Bitcoin payment ecosystem continues to grow, more and more options are becoming available for where you can spend your cryptocurrency:

Online retailers

Alternative methods

For many retailers that don’t accept Bitcoin, users can purchase gift cards using BTC. Alternatively, anyone with a Tap card can spend Bitcoin anywhere in the world that accepts Mastercard. Simply open an account and request a free card by entering your address on the app (some location limits apply). 

How to convert Bitcoin to cash

When you need to convert Bitcoin to traditional currency, you have three main options:

• Cryptocurrency exchanges (access to the top prices through Tap)
• Peer-to-peer marketplaces (platforms like LocalBitcoins)
• Bitcoin ATMs for immediate cash withdrawal

Alternatively, you can use your Tap card at any traditional ATM and withdraw the local currency. 

Things to look out for

When using Bitcoin for payments, it’s important to keep a few things in mind. Pay attention to exchange rates and transaction fees (displayed before you confirm the transaction) as they can vary between platforms. 

Processing times might also differ depending on network congestion. Additionally, be aware of verification requirements and daily withdrawal limits of the platform you use, which could affect how much and how quickly you can transact.

Security and best practices

Transaction safety

Always make sure that your Bitcoin is protected by following these security measures:

• Double-check recipient addresses
• Use secure internet connections
• Enable two-factor authentication
• Keep software and wallets updated

Risk management

Just to be on the safe side, to minimise risks when using Bitcoin for payments, start with small transactions to test the process and get comfortable with it. Also make sure you understand transaction fees and confirmation times, as mentioned above, as these can impact your experience. 

Last but not least, always keep records of your transactions and stick to reputable services and merchants to ensure a safe and reliable payment process.

Tax and legal considerations

Using Bitcoin can have tax implications, so it’s important to understand your responsibilities relative to the area that you live. You may need to pay taxes on any increase in value, keep detailed transaction records, report payments, and consider tax rules if you’re using Bitcoin for business purposes.

To stay compliant with regulations, keep detailed transaction records and understand any reporting requirements. Follow KYC (Know Your Customer) and AML (Anti-Money Laundering) procedures on the platforms you use, and consult a tax professional if needed to ensure you’re meeting all obligations.

Going a little deeper

Understanding the technology

In a very concise nutshell, the Bitcoin network operates through:

• Blockchain technology for transaction verification

When making purchases with your debit card, you’re typically asked to provide a security code, also known as a CVV or CVV2 code. This 3-digit (or sometimes 4-digit) number is an important security feature that helps protect your card from unauthorised use. Understanding what this code is, where to find it, and why it's crucial to keep it safe can help prevent financial fraud and give you greater control over your accounts. In this article, we dive into the details.

What is the security code used for?

The debit card security code serves a critical purpose in verifying your identity and protecting against fraudulent activity. When you provide the code during a transaction, it confirms that you physically possess the card, rather than just having access to the card number alone. 

This helps prevent criminals from making unauthorised purchases, especially for online, phone, or mail-order transactions where the physical card is not present. By requiring the security code, merchants and financial institutions can have an additional safeguard against fraud, giving you greater confidence that your hard-earned money stays secure.

Why are debit card security codes important?

The bottom line is that debit card security codes play a vital role in safeguarding your financial information and protecting your hard-earned money. This security code acts as an additional layer of security beyond just your card number and expiration date and without it, criminals would have a much easier time making unauthorised purchases or accessing your accounts. 

Where can I find my debit card security code?

The debit card security code is typically found in one of two places on your card: 

On most standard debit cards, the 3-digit code is printed on the back of the card, often in the signature strip or just to the right of it. 

Some debit cards may have a 4-digit security code that is printed on the front of the card, usually in the top right corner. 

How debit card security codes work with contactless payments

While debit cards with security codes are primarily used for in-person, online, and over-the-phone transactions, the code also plays a role in contactless or "tap-to-pay" payments. 

When you hold your debit card up to a contactless payment terminal, the 3- or 4-digit security code is digitally transmitted along with your card information. This allows the payment system to verify your identity and approve the transaction, just as it would for a contact-based payment that requires manually entering the security code. 

The security code therefore provides an extra layer of protection, even for quick tap-and-go purchases.

CVV vs OTP

The key difference between a debit card's CVV (card verification value) code and an OTP (one-time password) lies in how they function to verify transactions. A CVV is a static 3 or 4-digit code printed on your physical debit card, which you manually enter to confirm your identity. 

In contrast, an OTP is a dynamically generated code, typically sent to your mobile device via SMS from the bank or an authentication app, that changes with each new transaction. While both add an extra security layer, OTPs provide stronger protection, as they cannot be reused like a static CVV. 

Combining the use of your debit card's CVV code and a one-time password (OTP) provides the strongest protection against financial fraud.

CVV vs PIN

Your debit card's PIN (Personal Identification Number) is different from the CVV (card verification value) code.

The PIN is used to verify in-person transactions when you use the physical card, like at a store checkout or ATM.

The CVV code is used instead for remote purchases, like online or over the phone, where the physical card isn't present.

Closing thoughts

In summary, the debit card security code, also found on a credit card, is an essential safeguard against fraud and unauthorised transactions. By understanding what this code is, where to find it, and how it protects your finances, you can take control of your financial security and enjoy greater peace of mind when using your debit card in the wild or online.
