In today's fast-paced world and ever-evolving financial landscape, cryptocurrencies have emerged as a revolutionary digital asset class. With their blockchain technology, decentralized nature, and potential for high returns, there’s no denying that cryptocurrencies have captured the attention of both novice and seasoned investors. 

In this article, we will delve into the advantages and disadvantages of cryptocurrency, shedding light on their accessibility, potential returns, and security, as well as the challenges they pose to beginners. If you’re curious about cryptocurrencies or are on the fence about whether they’re a viable addition to your portfolio, we hope the following can shed some light on the matter.

The pros of cryptocurrency

Accessibility and inclusivity

Cryptocurrencies have democratized financial systems, providing individuals around the world with access to previously inaccessible financial services. Powered by blockchain technology, their core aim is inclusivity.

By eliminating intermediaries like financial institutions, digital currencies offer greater financial freedom and empowerment to anyone, anywhere. This includes lower transaction fees and around-the-clock operations as cryptocurrency markets never close.

Additionally, the reduced transaction costs associated with cryptocurrency transactions make them an attractive alternative for cross-border payments, for both individuals and businesses alike. Transactions that previously took days to complete through financial institutions can now be executed in minutes for a much lower cost thanks to cryptocurrency markets and the ability to transfer funds directly.

High-risk, high reward

Cryptocurrencies are renowned for having volatile price movements, however, this isn’t always a negative thing. The volatile nature of cryptocurrencies presents unique investment opportunities. While this volatility comes with risks, it has also been the catalyst for the success stories of early adopters who have seen substantial returns on their investments. 

For beginners with an appropriate degree of risk tolerance willing to navigate the market carefully, cryptocurrencies can offer the potential for significant financial gains.

Security and privacy

Cryptocurrencies make use of cryptographic encryption to ensure secure crypto transactions and protect user privacy. The underlying blockchain technology provides a transparent and immutable ledger that safeguards against fraud and tampering thereby giving users greater control over their financial information. With the use of a private key system, retrieved when creating a crypto wallet, users have sole access to their cryptocurrency at all times.

Due to the nature of blockchain, cryptocurrency transactions are pseudonymous (and on some decentralized networks offering private transactions, anonymous) allowing for greater privacy when it comes to one’s financial matters. This means that when conducting Bitcoin transactions, for instance, the wallet address of the sender and receiver will be stored on the blockchain ledger as opposed to the names associated with the accounts.

The cons of cryptocurrency 

Volatility and risk

While discussed as a pro of trading cryptocurrencies, volatility can also be a con. The biggest one is that the unpredictable price fluctuations of a digital currency can be intimidating for beginners. Market uncertainty, driven by factors like regulatory changes and investor sentiment, can result in significant losses. 

Additionally, the lack of regulations in the cryptocurrency market makes it susceptible to scams and fraudulent activities such as money laundering, which can pose a risk to unsuspecting investors. Always ensure that you are using a reputable platform to trade and manage your digital currency.

Technical complexity

As cryptocurrencies operate on complex technological frameworks, it's often assumed that there is a big learning curve for beginners entering the crypto markets. Understanding concepts such as how a digital wallet works, what a private key is, and blockchain can be overwhelming initially but with our library of informative and easy-to-digest content, users can bypass the overwhelm. Our content is created to empower crypto enthusiasts looking to navigate the world of digital assets and decentralized currency.

Ensuring the security of cryptocurrency holdings and managing wallets require a certain level of caution and online security to prevent loss or theft. To bypass this obstacle Tap has created an easy-to-use app that allows for the management of multiple crypto and fiat currency in one hyper-secure place. 

Limited acceptance and adoption

Perhaps the greatest hindrance to the world of cryptocurrency is its slow-paced adoption. While the acceptance of cryptocurrencies is growing, it remains limited compared to traditional fiat currencies. 

Not all merchants and businesses accept cryptocurrencies as a form of payment, which restricts their usability in daily financial transactions. On top of this, the lack of mainstream recognition and regulatory frameworks presents challenges for the wider adoption of crypto transactions.

Conclusion

As a beginner exploring the world of cryptocurrencies, it's crucial to weigh the advantages and disadvantages before diving into the cryptocurrency market. While digital assets offer accessibility, the potential for high returns, and enhanced security and privacy, there are also the disadvantages of cryptocurrency such as risks related to volatility, technical complexity, and limited acceptance. 

When investing or trading cryptocurrency, it's essential to proceed with caution, conduct thorough research, and consider personal risk tolerance and investment goals. By staying informed and always conducting their own research, beginners can navigate the digital asset landscape effectively and make informed investment decisions.

Remember, cryptocurrencies are a rapidly evolving space, and continuous learning and adaptation are key to staying ahead. Stay informed, monitor market trends, and explore reputable resources to expand your understanding of digital assets and blockchain technology and their potential in the ever-changing financial landscape.

Here we discuss what dividends are and how they work so you can make informed decisions when investing in dividend paying stocks. As a company, regular dividend payments create an incentive for shareholders to remain invested and keep the business growing, while for investors a dividend payment can increase the overall ROI and provide additional income streams. Learn the difference between stock dividends and cash dividends below.

What is a dividend?

Dividends are a way for companies to share their profits with shareholders. When a company earns profits, it can choose to distribute those profits back to its shareholders in the form of dividends. Dividend payments are typically made in cash and are usually paid out every quarter or semi-annually. Dividend paying companies can also choose to pay stock dividends, which is essentially dividend income paid out in shares.

By investing in dividend paying stocks, investors have the potential to earn regular income from their investments as well as benefit from capital appreciation when stock prices rise.

Dividend paying stock and the stock exchange

Investors in the stock market can earn returns in two ways, one is through an increase in the stock price from when they purchased it, and the other is through dividends. A company can decide whether they pay out dividends or not, and it's worth noting that not every company on the stock market does pay out dividends. The ones that do are typically mature ones. 

Companies might instead decide to use the profits to reinvest in the company, hire new employees, or expand their business. Start-ups and newer companies are more likely to take this approach as their goals are more aligned with growth. 

These payments are made in cash and generally occur at regular intervals, be it quarterly or annually. The amount per share, and when and how often dividends are paid out are determined by the company's board of directors.

Why a company might pay dividends 

When a company is profitable, it might do one of these three things with its profits:

• pay off debt
• chase a growth opportunity by reinvesting the money into the business
• pay dividends to their shareholders, attracting new ones and rewarding current ones

Companies pay dividends to reward their shareholders, generating a steady income stream, and increasing the overall value of their stock. Additionally, dividend payments can be used to attract new investors and signal financial strength. Only profitable companies will pay out dividends, and typically ones without significant debt. 

Stocks that pay dividends

Whether a company pays dividends is directly related to its goals and priorities. As mentioned above, younger companies typically use profits to reinvest in the business as the current goal is growth, while more mature, established companies opt to reward (and attract) shareholders. 

Growth stocks

Companies looking to capitalize on growth opportunities might make the wiser move by reinvesting their earnings instead of offering dividends to shareholders. 

Let's use retail as an example. If a company has just released a new product, it'd likely benefit more from hiring additional salespeople who can promote it than partaking in payouts for investors. In doing so, this allows the business to seek out maximum returns and drive the stock price up instead of giving away potential gains prematurely.

Mature stocks

As companies reach their peak and shift to a sustaining stage, they are more likely to prioritize dividend payments for shareholders over investing any additional funds into growth. 

Ultimately, leaders must determine what is best for the company's shareholders depending on its size and age: paying dividends, funding development opportunities, or debt reduction. The ideal choice depends heavily upon the organization’s state of expansion as well as other considerations.

Mutual funds and ETFs

Investors in mutual funds and exchange-traded funds can also tap into dividend income provided that the stocks pay dividends. These are typically paid out on an annual basis, however, this will be determined by the shareholder's brokerage account.

Timeline of dividend payouts

Whether a company pays out dividends at regular intervals or on a once-off basis, below are several dates to note with regard to the when and how of these payments. From the declaration date to the ex-dividend date to the payment date, these all play an important role for investors looking to benefit from dividend yield.

• The Declaration Date

When the Board of Directors announces the value, record date, and payment date for the upcoming dividend.

• Ex-Dividend Date

The ex-dividend date is the final date by which you can buy the stock and earn dividends. If you purchase stock after the ex-dividend date you are not liable to receive dividends. Stock purchases can sometimes take two days to clear so ensure that you do so at the right time. 

• Record Date

The date that you need to be an official shareholder in order to receive dividends. If your stock purchase is not settled by this date you are not liable for the payouts. The record date is typically one date after the ex-dividend date.

• Payment Date

When payments are made to all registered shareholders (as of the record date). Depending on the preferences specified in your brokerage account, the dividend could either be credited to you as cash (cash dividends) or reinvested back into the issuing business, distributed as stock dividends. 

How dividend payments can affect the share price

Due to dividends being paid out by profitable businesses, when a business does pay out dividends this sends a signal to the market that the business is doing well and could drive the stock price up. However, it could have the opposite effect too, driving the price down when there is no dividend payout. 

• when dividends drive the stock price up

Dividends can be a celebration of a company's profits and act as rewards to shareholders for investing in the company. This makes the stock more attractive to investors looking to earn passive income and will ultimately drive the price up. 

• when dividends drive the stock price down 

Companies generally pay dividends only when they are assured that the rate of return can be sustained, thanks to reliable profits. Therefore, if a company announces any reduction in this rate of dividend payment, it is likely because their business is encountering certain difficulties, sending out a negative signal instead.

In conclusion: what is a dividend payment?

A dividend is a payment that companies make to their shareholders, usually in the form of cash or stock. It's a type of reward for investors who have held onto the company's shares for a certain period of time. Usually companies pay dividends on a quarterly basis, often based on a portion of the company’s profits.

Because dividends are usually paid in cash, they can be a great source of income for investors. This extra income comes with less risk than other types of investing, which makes them attractive to many people who are looking for reliable returns on their investments. Dividend stocks also tend to outperform the overall stock market.

Public and private keys are integral to the use of cryptocurrencies. They not only allow people to send and receive cryptocurrencies but also to maintain the security and ownership of the funds. Private and public keys are generated when one creates a digital wallet.

What is a private key?

Every cryptocurrency wallet consists of a public key and a private key. Anyone can deposit cryptocurrency into a public address (public key), but no one except the owner of the corresponding private key can remove funds from that same account.

A private key, also known as a secret key, is a random string of numbers and/or letters used to protect one's cryptocurrency wallet and receive crypto transactions, similar to a pin code for a bank account. Private keys prove ownership of one's wallet address, protect it from unauthorized access and theft, and are used to sign transactions on the blockchain. 

Private keys are used in conjunction with an algorithm to encrypt or decrypt data. The holder of the private key should be the only one who knows it, as this secrecy is what gives the private key its power. The golden rule is to keep your private key safe.

Private key vs public key

Public and private keys are mathematically linked to each other and relevant to only one blockchain wallet. A public key can be compared to your traditional bank account while the private key is akin to the pin code to access this account. 

Users would share the public key with anyone looking to transfer funds to their crypto wallet, however, under no circumstances should your unique private key ever be shared with anyone. It is also strongly recommended that one stores their private key offline in a safe space, and not on a desktop or accessible location (in the event of a hack).

When one loses their private key, whether lost or maliciously taken, they will lose access to their crypto funds. Due to the decentralized nature of cryptocurrencies, there is no support line or central authority that can access that information.

This is where exchange wallets come in handy as the account is created using an identity that once verified can gain access to the funds. This is known as a custodial wallet where the platform holds the private keys for you and allows you to access the funds through a user-generated password. When it comes to storing private keys, this is the most convenient option, however, if you use an untrustworthy platform that increases your risks greatly. It is strongly recommended to enable two-factor authentication when using this option.

How do private keys work?

A public key is generated using complicated mathematics by your private key, ensuring they form a matched pair. These digital keys are created when one creates their crypto wallet on a particular blockchain. 

After being generated, a private key must be stored in a secure location, ideally offline. Furthermore, private keys can have an extra layer of security by being password-protected, encrypted or hashed, ideally all three.

The owner of the public key will use the private key to encrypt the digital signature when making a transaction. 

A transaction is encrypted using a public key and can only be decrypted by using the matching private key. Therefore, when someone sends a transaction they will need their private key to decrypt and prove they own the funds being used in this transaction. 

The private key is used to sign the transaction, which verifies that the transaction hasn't been modified. A digital signature is created when someone combines their private key with the data that's being sent as part of a transaction. 

Once the transaction has been executed the nodes on the network will check and authenticate the details of the transaction and if any information is incorrect the transaction will be rejected. Once executed transactions cannot be reversed. 

Where should you store your private key?

Your private keys are essentially your passwords, so it's of utmost importance that you keep them safe.  Your best bet is to store them offline somewhere safe. This might mean written on a piece of paper, stored on an offline device, or kept in a password manager.  As mentioned above, public keys can be stored anywhere and shared with anyone.

To avoid the hassle and stress of ensuring the safety of your private keys at all times, you can use a hot wallet supplied through a reputable exchange. If you choose to take this route ensure that the crypto platform is regulated and adheres to stringent security measures. The Tap app ticks these regulatory boxes and ensures that customers have full access to their funds at all times, without the risk of losing them if they lose their private keys. 

In conclusion

Private keys are digital passwords used to establish one's ownership in a crypto wallet and are created in conjunction with the public key of the same wallet. One should never share their private keys with anyone.

Since the debut of Bitcoin in 2009, central banks have been living in fear of the disruptive technology that is cryptocurrency. Distributed ledger technology has revolutionized the digital world and has continued to challenge the corruption of central bank morals. 

Financial institutions can’t beat or control cryptocurrency, so they are joining them in creating digital currencies. Governments have now been embracing digital currencies in the form of CBDCs, otherwise known as central bank digital currencies. 

Central bank digital currencies are digital tokens, similar to cryptocurrency, issued by a central bank. They are pegged to the value of that country's fiat currency, acting as a digital currency version of the national currency. CBDCs are created and regulated by a country's central bank and monetary authorities.

A central bank digital currency is generally created for a sense of financial inclusion and to improve the application of monetary and fiscal policy. Central banks adopting currency in digital form presents great benefits for the federal reserve system as well as citizens, but there are some cons lurking behind the central bank digital currency facade.

Types of central bank digital currencies

While the concept of a central bank digital currency is quite easy to understand, there are layers to central bank money in its digital form. Before we take a deep dive into the possibilities presented by the central banks and their digital money, we will break down the different types of central bank digital currencies. 

Wholesale CBDCs

Wholesale central bank digital currencies are targeted at financial institutions, whereby reserve balances are held within a central bank. This integration assists the financial system and institutions in improving payment systems and security payment efficiency. 

This is much simpler than rolling out a central bank digital currency to the whole country but provides support for large businesses when they want to transfer money. These digital payments would also act as a digital ledger and aid in the avoidance of money laundering.

Retail CBDCs

A retail central bank digital currency refers to government-backed digital assets used between businesses and customers. This type of central bank digital currency is aimed at traditional currency, acting as a digital version of physical currency. These digital assets would allow retail payment systems, direct P2P CBDC transactions, as well as international settlements among businesses. It would be similar to having a bank account, where you could digitally transfer money through commercial banks, except the currency would be in the form of a digital yuan or euro, rather than the federal reserve of currency held by central banks.

Pros and cons of a central bank digital currency (CBDC)

Central banks are looking for ways to keep their money in the country, as opposed to it being spent on buying cryptocurrencies, thus losing it to a global market. As digital currencies become more popular, each central bank must decide whether they want to fight it or profit from the potential. Regardless of adoption, central banks creating their own digital currencies comes with benefits and disadvantages to users that you need to know. 

Pros of central bank digital currency (CBDC)

• Cross border payments
• Track money laundering activity 
• Secure international monetary fund
• Reduces risk of commercial bank collapse 
• Cheaper
• More secure
• Promotes financial inclusion

Cons of central bank digital currency (CDBC)

• Central banks have complete control
• No anonymity of digital currency transfers
• Cybersecurity issues 
• Price reliant on fiat currency equivalent 
• Physical money may be eliminated 
• Ban of distributed ledger technology and cryptocurrency

Central bank digital currency conclusion

Central bank money in an electronic form has been a big debate in the blockchain technology space, with so many countries considering the possibility. The European Central Bank, as well as other central banks, have been considering the possibility of central bank digital currencies as a means of improving the financial system. The Chinese government is in the midst of testing out their e-CNY, which some are calling the digital yuan. They have seen great success so far, but only after completely banning Bitcoin trading.

There is a lot of good that can come from CBDCs, but the benefits are mostly for the federal reserve system and central banks. Bank-account holders and citizens may have their privacy compromised and their investment options limited if the world adopts CBDCs.

It's important to remember that central bank digital currencies are not cryptocurrencies. They do not compete with cryptocurrencies and the benefits of blockchain technology. Their limited use cases can only be applied when reinforced by a financial system authority. Only time will tell if CBDCs will succeed, but right now you can appreciate the advantages brought to you by crypto.

Bitcoin has become a worldwide phenomenon due partly to its incredible innovation in terms of technology and cross-border payments, but also because of its unbelievable market performance over the last decade.

The original cryptocurrency was even voted the top performing asset of the past decade, and there is no denying why. So, how does it all work? Today we’re uncovering everything you need to know about the inner workings of the most powerful cryptocurrency.

Bitcoin 101

Before we dive into how Bitcoin works, let’s cover the basics. Bitcoin is a peer-to-peer electronic payment system that was launched in 2009 by Bitcoin's creator, Satoshi Nakamoto, an anonymous entity that remains a mystery to this day. The Bitcoin blockchain ignited blockchain technology, propelling it into the 21st century and allowing anyone connected to the internet to embrace the new age of technology.

Bitcoin was designed as a response to the global financial crisis and set to be a decentralized payment system that was exempt from banking institutions’ central authority and errors. Over the past decade, the cryptocurrency has increased in value, hitting $20,000 for the first time in 2017, again in December 2020, before soaring to highs of $68,789.63 in November 2021.

The Bitcoin blockchain network has also paved the way for many other virtual currencies, of which there are currently over 20,000. The industry has grown into a sizable $1 trillion market (valued at one stage at over $3 trillion), most of which has Bitcoin to thank. Bitcoin currently dominates the market with a 40% share and has created a name for itself in the mainstream as more and more businesses decide to accept Bitcoin.

How exactly does Bitcoin work?

Now that we’ve covered the basics, let’s get into the nitty-gritty. As previously mentioned, Bitcoin is a peer-to-peer digital currency that does not rely on any third-party financial institutions, banks or governments. Instead, the network and all Bitcoin transactions are operated by a network of nodes (computers) and miners. Users store Bitcoin in a digital wallet.

In simple terms, miners are responsible for verifying transactions while nodes keep records of all the transactions on the Bitcoin network. All transactions are added to the blockchain, which is a public ledger of all activity on the Bitcoin network. This is a simple look at how Bitcoin mining works.

Looking more deeply into this, let’s say one person in Belgium is sending Bitcoin to someone in England. The Belgium person will enter the Bitcoin address (also known as a wallet address) of the recipient and indicate how much they would like to send. The Bitcoin wallet through which it is being sent will calculate the transaction fees, the Belgium person will confirm (also checking they are happy with Bitcoin's price), and the Bitcoin transaction will enter a “mempool” of new transactions.

From here, Bitcoin miners will fight to solve a complex mathematical puzzle and the first one to do so correctly will be allowed mine the next block and verify all pending Bitcoin transactions (the process of Bitcoin mining). The miner will then verify that all senders of the transactions have sufficient balances, and the transactions will be executed.

The miner will then add the new block to the blockchain, and it will be circulated amongst the network. Once all the nodes approve, they will all update their blockchain records with the new block.

The person in England will then get a notification to say that they have received the Bitcoin transaction, and will most likely require 3 confirmations before being able to access the funds (some digital wallets and merchants require 6 confirmations). Confirmations are represented by new blocks added to the blockchain following the block with that specific transaction. Blocks take 10 - 40 minutes to be created due to the Bitcoin mining process.

While this is how Bitcoin transactions take place, other cryptocurrency transactions might vary slightly.

Where do new Bitcoins come from?

Satoshi Nakamoto designed the cryptocurrency to be deflationary in nature, intending the price to increase over time as opposed to decreasing like fiat currencies, offering not only a reliable payment method, but also an investment opportunity. Bitcoin has a fixed supply of 21 million coins, with a certain number being released each year.

Initially, the mining reward for mining a block on the Bitcoin blockchain was 50 BTC, but after every 210,000 blocks (roughly 4 years) the reward halves. In May 2020, the third halving took place, driving the block rewards down to 6.25 BTC per block. This equates to roughly $230,000 at the time of writing.

So where do new Bitcoins come from? Each time a miner verifies a bundle of transactions, the miner will receive each transaction’s network fee and once they have mined enough transactions to complete a 1MB block and add it to the blockchain, they will receive the mining reward too. 

Once the 21 millionth coin has been mined no new coins will ever enter circulation.

Si vous cherchez à générer des revenus passifs avec vos cryptomonnaies, vous avez probablement déjà entendu parler du staking et du yield farming. Ces deux pratiques sont devenues incontournables dans l’univers de la finance décentralisée (DeFi), mais elles fonctionnent de manière bien différente.

Dans cet article, on vous explique clairement la différence entre staking et yield farming, leurs avantages, leurs risques, et comment vous lancer.

Qu’est-ce que le Yield Farming ?

Le yield farming (ou agriculture de rendement) consiste à placer vos cryptos sur des plateformes DeFi pour obtenir des rendements, souvent sous forme d’intérêts ou de jetons bonus.

Cela se passe principalement via :

• des plateformes de prêt comme Aave ou Compound, où vous prêtez vos actifs contre intérêts ;
• des échanges décentralisés (DEX) comme Uniswap ou PancakeSwap, où vous fournissez des liquidités à une paire de tokens et gagnez une part des frais générés.

Vos revenus proviennent des intérêts payés par les emprunteurs ou des frais de transaction du pool auquel vous participez. Le tout est géré par des smart contracts, sans intervention humaine.

Qu’est-ce que le Staking ?

Le staking consiste à verrouiller vos cryptos dans un contrat intelligent pour participer à la sécurité du réseau blockchain et en retour, recevoir des récompenses.

Le staking repose sur le mécanisme de Proof of Stake (PoS), utilisé par de nombreuses blockchains comme Ethereum, Cardano ou Polygon. En stakant vos tokens, vous aidez à valider les transactions et à sécuriser le réseau.

Vous pouvez :

• devenir validateur si vous avez les compétences et les fonds suffisants ;
• ou rejoindre un pool de staking via une plateforme comme Tap, Binance ou un portefeuille crypto.

Chaque blockchain a ses propres règles : période de verrouillage, rendement (APY), conditions d’entrée…

Quelle est la différence entre Yield Farming et Staking ?

Même si les deux méthodes permettent de générer un revenu passif, elles ont des fonctionnements, des rendements et des risques différents :

CritèreYield FarmingStakingFonctionnementFourniture de liquidités sur une plateformeVerrouillage de tokens pour sécuriser un réseauRendement potentielJusqu’à 100% APY (variable et risqué)Environ 4 à 10% APY (plus stable)VerrouillageGénéralement sans durée imposéeParfois avec un délai fixe ou un minimum requisRisqueRisque de bugs dans les smart contractsRisque faible si le validateur agit honnêtementRécompenseProportionnelle à la performance du poolBasée sur la création de blocs et le staking

Quels sont les avantages de chacun ?

✅ Les avantages du Yield Farming :

• Rendement potentiellement élevé
• Flexibilité des plateformes
• Possibilité de participer à des projets innovants

✅ Les avantages du Staking :

• Plus stable et prévisible
• Moins risqué
• Facile à mettre en place via un exchange ou un wallet

Alors, quelle option choisir ?

Il n’y a pas de réponse unique. Tout dépend de votre appétence au risque, de votre niveau de connaissance dans la DeFi, et de vos objectifs :

• Si vous recherchez la sécurité et la simplicité, le staking est une très bonne option.
• Si vous êtes à l’aise avec les outils DeFi et cherchez des rendements élevés, alors le yield farming peut vous convenir, à condition de bien gérer les risques.

Dans tous les cas, prenez le temps de vous informer sur les plateformes, les tokens, et les règles spécifiques à chaque protocole.

En résumé

Staking ou Yield Farming, les deux offrent des opportunités intéressantes dans l’univers crypto pour générer des revenus passifs. Le staking repose sur la sécurisation des blockchains via la preuve d’enjeu, tandis que le yield farming vous permet de tirer parti des opportunités offertes par la DeFi.
