DeFi (decentralised finance): what it is in cryptocurrency

Home » blog » DeFi (decentralised finance): what it is in cryptocurrency


The financial system is undergoing rapid change and new technologies are becoming increasingly important. Decentralised finance, or DeFi, challenges established banking structures by offering an alternative to traditional methods of capital management. Investors, traders and ordinary users can now communicate directly with each other through smart contracts without an intermediary.

In this article, we explain in detail what DeFi is, how it is used in cryptocurrencies and discuss other aspects of the topic.

What is DeFi and why is it important?

DeFi: what is cryptocurrency? A system of financial instruments and services on the blockchain that does not involve intermediaries such as banks and brokers. The essence of the mechanism is to create open and accessible financial services for all, where any user can participate in the global market.

Definition of decentralised finance: short and clear

DeFi is a decentralised ecosystem of financial applications running on the blockchain. Unlike traditional finance, where control is concentrated in the hands of central authorities, DeFi offers transparency and autonomy. The definition can be boiled down to three main aspects:

  1. Accessibility: Participation in DeFi requires no special permissions or verification. All you need is internet access and a cryptocurrency wallet.
  2. Transparency: All transactions are recorded on the blockchain, making manipulation impossible.
  3. Security: smart contracts replace middlemen, reducing the risk of human error.

How DeFi works: from smart contracts to apps

It is based on blockchain and smart contracts: automated programmes that execute the terms of a transaction without third-party intervention. Let’s look at the mechanism through a specific example.

Imagine you need to exchange ETH for another token. In a traditional system, an intermediary is needed to ensure the security of the transaction. In DeFi, this function is performed by an application based on smart contracts. One of the most popular exchange protocols is Uniswap. It allows users to trade tokens directly through a liquidity pool rather than through a traditional order.

This means that DeFi in cryptocurrencies enables people not only to trade assets, but also to make loans and invest without bank control. Protocols like Compound allow borrowers to earn interest on the deposited assets. Moreover, they can receive the money immediately if they provide collateral.

DeFi in simple terms: what is it in cryptocurrency?

What is DeFi and why is it important?Understanding decentralised finance is not as difficult as it seems. Imagine a world where financial services are available to all, without bank lines or bureaucracy.

DeFi for beginners: the first step to a new world

To get started, you need the following:

  1. Create a wallet: the most popular are MetaMask, Trust Wallet and Coinbase Wallet.
  2. Top up your balance: transfer ETH, for example, to work with apps.
  3. Connect to a DeFi app: use swapping, lending or staking protocols.
  4. Perform transactions: exchange assets, provide liquidity or apply for loans.

The important thing is to observe security and check smart contracts before you start working with them.

The benefits of DeFi: why the world is changing

Its benefits are becoming increasingly clear in the modern world, where flexibility and transparency in financial transactions are increasingly important.

Freedom, transparency and revenue: the main advantages of DeFi

  1. Freedom: no intermediaries needed. Any user can conduct transactions directly through the blockchain.
  2. Transparency: All transactions are recorded on the blockchain and can be verified by all network participants.
  3. Income: DeFi offers new opportunities for passive income through staking, farming and providing liquidity.

For example, through the Aave platform, users can lend their assets and receive interest. Similarly, Uniswap allows users to earn swap fees by providing tokens to a liquidity pool.

The future of DeFi: where is the financial world headed?

It is important to stress that DeFi in cryptocurrencies is not just a technological trend, but a financial revolution. Integration of DeFi projects with traditional financial systems is expected to increase rapidly in the coming years. Banks and companies are already testing blockchain solutions to optimise processes, increase transparency and reduce costs. This suggests that decentralised technologies are about to move beyond the crypto community and become part of everyday life.

Integrating DeFi with the real world

One of the key trends is the implementation of DeFi in payment systems and retail services. Today, some startups are already offering payments for goods and services directly through the blockchain, without intermediaries. For example, the Flexa platform allows you to pay with cryptocurrency at thousands of shops, including major retail chains. In the future, we can expect decentralised technologies to be integrated into applications for online shopping, delivery and other services.

Major payment systems like Visa and Mastercard are already testing the possibilities of integrating blockchain for instant and low-cost transactions. We can therefore conclude that DeFi forms a bridge between traditional money and crypto-currencies.

Improve user interfaces

Despite the huge potential, many DeFi applications are still complex for the general public. One of the biggest challenges remains improving interfaces and user experience (UX). Examples of these improvements can already be seen on platforms such as Aave and Compound, which provide clear dashboards and step-by-step instructions for beginners.

DeFi regulation and security

As the popularity of decentralised finance grows, so does the need for legal regulation. The development of legal frameworks for user protection will be one of the key trends in the coming years. Governments around the world are already working on creating a regulatory framework for DeFi projects. For instance, the United States, the European Union and China are developing rules for smart contracts and blockchain technologies.

Legal measures are aimed at protecting investors from fraud, ensuring the security of their assets and reducing the risk of losing money. In the future, transparent and clear cryptocurrency laws will help attract large institutional investments to DeFi, accelerating mass adoption of the technology.

Conclusion

 

The benefits of DeFi: why the world is changingIn short, in cryptocurrencies, DeFi is not just a buzzword, but a real tool to change the financial system. In a world where anyone can trade, borrow and make money without intermediaries, the possibilities are limitless. Decentralised finance puts you in control of your capital and creates the future of finance today.

The cryptocurrency market is once again in a cycle of expectations, highs and lows. Investors, traders and retail buyers are following the movement of BTC in search of an answer: is it worth buying Bitcoin now? The performance of assets is becoming increasingly important as an indicator of global economic confidence. In order to get in, a good understanding of both current data and future scenarios is essential.

Bitcoin price in 2025: is it worth buying now?

It is important to consider the current value before making a decision. Bitcoin trades within a range that is determined by three factors at once: expectations about the halving, the activity of large institutional players and the market sentiment regarding the macro economy. Support and resistance levels shift, volumes fluctuate, but interest remains constant.

When deciding whether or not to buy Bitcoin, you should not consider the price as a number, but as a context. The $60,000 level per coin is no longer seen as a ceiling, but rather as a balance between the fear of a correction and the desire to get in “before the growth”.

Halving as a trigger: why it is not just an event

Bitcoin price in 2025: is it worth buying now?Every four years, the BTC network algorithm automatically halves the block reward. The next halving is expected to occur in 2024, and its delayed impact will be felt precisely in 2025. A decrease in supply always comes with a wave of speculative and fundamental growth. The Bitcoin prediction for 2025 should take this mechanism into account. Statistics from previous cycles show an average growth of 300% within 12 months after the halving.

Expert Predictions: Is It Worth Buying Bitcoin Now?

BTC predictions are not assumptions, but rather a strategy based on a comparison of historical data, asset performance, and market reactions to external factors. Bitcoin 2025 analysis shows mixed patterns, but within the conditional confidence zone.

What analysts are saying about BTC in 2025:

  1. Technical traders are looking at a range scenario of $90,000 to $120,000 in the absence of negative regulatory factors.
  2. Financial analysts are expecting a rally above $100,000, solely due to the mass adoption of ETFs and a stable dollar.
  3. Equity strategists are targeting a range of $80,000 to $110,000, as interest from corporate investors grows.
  4. Crypto enthusiasts are expecting speculative price increases to $150,000, but only in the short term.
  5. Macroeconomists see the dollar, interest rates and geopolitics as determining factors.

The numbers show that the growth potential is still strong.

ETFs and institutional players: new entrants to the market

The approval of BTC ETFs in the US has changed the demand structure. Buyers today include pension funds, corporate funds, and long-term strategists. The huge influx of liquidity increases volatility, but also creates support for the asset. Investing in cryptocurrencies is no longer a niche hobby. In the past, the decision to buy stocks was based on a trade-off between risk and return. Now, inflation and capital preservation play a major role. Bitcoin’s prospects are not strengthened by speculation, but by institutionalization.

Dollar, Ruble, and the Global Market: Macroeconomics vs. Emotions

The decision to buy BTC never takes place in a vacuum. An investor always compares risks and prospects with other assets, mainly currencies. As the ruble loses stability and the dollar strengthens, cryptocurrencies become an alternative to traditional monetary instruments. In the context of the devaluation of the national currency, Bitcoin acts as digital gold: a protective asset with a limited issuance.

Analysis of Bitcoin 2025 shows that it reacts not only to crypto events, but also to general market trends. For example, after increasing sanctions pressure or sudden inflation spikes in developing countries, there is a sharp increase in local demand for BTC. The rising trading volumes in rubles, Turkish lira, Argentine pesos and other weakened currencies emphasize that cryptocurrencies are becoming a universal response to instability.

In the global system, BTC influences the policies of central banks. The interest rate decisions of the Federal Reserve affect liquidity and thus investor sentiment. When the rate rises, the dollar becomes more expensive and risky assets, including cryptocurrencies, become cheaper. However, the fall in interest rates has the opposite effect: investors switch to alternative instruments and the BTC price gets a boost.

The trade war between China and the US, military conflicts, sanctions, currency fluctuations: all these factors form the background for decision-making. Whether to buy Bitcoin or not depends on an investor’s ability to analyze macroeconomic signals and act calmly, without panicking.

BTC as a hedge against devaluation

While the ruble depreciates by 20% every quarter, Bitcoin is growing by 30-50% in local currency terms. The 2022 example showed how, even with the sideways movement of the BTC exchange rate in dollars, the value of the asset in rubles almost doubled. This dynamic makes cryptocurrencies a tool to maintain purchasing power in times of fiat currency instability.

When to Buy Bitcoin: For the Goal, Not the Price

The question is not “where is the price?” but “where is the goal?” An investor who buys BTC without a clear strategy is held hostage by market fluctuations. On the contrary, those who understand why and how to build a portfolio make informed decisions, even in times of adversity.

Buying cryptocurrency without knowing the goal is like a journey without a route. Some traders try to ride the wave in the short term and get out after a week, while others build a position over a period of 3 to 5 years and ignore temporary declines. The “buy & hold” strategy shows a positive result over a period of 4 years: in 95% of cases, the investor makes a profit, even if he has not bought the minimum amount.

The Bitcoin price in 2025 reflects the current situation, but does not determine future income. The psychological trap of entering at the bottom and exiting at the top ruins the planning. It is much more important to manage risks intelligently:

  • allocate a portion of capital that can be frozen;
  • choose an exchange with a reliable infrastructure;
  • ensure storage security: cold wallets, multi-signatures;
  • understand the tax implications of transactions in your jurisdiction.

investor profile and entry point

A beginner looking for a ‘quick X’ often ends up in the – due to impulsive actions. An experienced participant sees BTC as an anti-crisis tool with long-term potential. Whether or not you should buy Bitcoin depends on your willingness to wait, learn and plan instead of gambling.

Cryptocurrencies are not a lottery or a speculative toy. It is a tool that works on the basis of understanding and time. Anyone who buys BTC with a horizon of 3-5 years is acting wisely, even at a hypothetical price of $70,000, because they are looking at the trend and not at the time.

Is it worth buying Bitcoin? Conclusions

Expert Predictions: Is It Worth Buying Bitcoin Now?Whether it’s worth buying Bitcoin now doesn’t depend on the number on the screen, but on your willingness to see the structure behind it. The halving, ETFs, the global economy, institutional buying, market behavior, and fundamental analysis mean that buying BTC is no longer a risk, but rather a calculation.

Cryptocurrencies haven’t just changed the financial landscape; they’ve completely revolutionized it. But if you still think that there’s only Bitcoin, it’s time to find out what’s behind this plethora of digital assets. In addition to popular currencies, there are dozens of other currencies with unique features and purposes. In this guide, we’ll explain what types of cryptocurrencies there are, how they differ, and how to choose the right one for you.

Main Types of Cryptocurrencies: From Classic to Memecoins

Apart from being the first cryptocurrency, Bitcoin is also a kind of “digital gold” and remains an important part of the financial ecosystem. Created in 2009 by Satoshi Nakamoto, Bitcoin is intended as a decentralized alternative to traditional currencies, without any middlemen or government control.

Then there’s Litecoin, often referred to as Bitcoin’s “lighter brother.” Created in 2011 by Charlie Lee, it has a number of distinguishing features, including faster transactions and lower transfer fees. These cryptocurrencies are called classic because they are designed to facilitate financial transactions and innovation.

Why use classic cryptocurrencies?

  1. Payments: They allow you to quickly and easily transfer money around the world.
  2. Store of value: Since the supply of Bitcoins is limited, they can serve as a store of value.
  3. Long-term investments: Classic cryptocurrencies have long proven themselves as reliable assets for long-term storage.

In this context, the types of cryptocurrencies are primarily classified according to their purpose: classic cryptocurrencies were developed to become financial instruments, but other types have their characteristics and applications.

Memcoins: what they are and why they are trending

Memcoins are a type of cryptocurrency that started as a joke project and suddenly became popular thanks to internet memes and an active community. Dogecoin and Shiba Inu are two of the most notable examples of cryptocurrencies that have evolved from funny memes to serious assets:

  1. Dogecoin was created in 2013 as a parody of Bitcoin and depicts a dog that is popular as an internet meme. Today, it enjoys enormous social support and is expected to exceed $10 billion in market capitalization by 2023.
  2. The Shiba Inu has become known for its cult status and sudden price increases, often as a result of social media attention or celebrity tweets.

Memcoins: What are they? —In short, they are cultural phenomena that are not driven by algorithms, but by internet communities and trends.

Importance:

  1. Community: The success of memecoins often depends on the solidarity among their users.
  2. Innovation: Although many memecoins are temporary phenomena, they raise questions about the role of the community in determining the value of cryptocurrencies.
  3. Risk and return: Investing in memecoins always involves a high level of risk, but also the possibility of sudden price increases.

The main differences between classic cryptocurrencies and memecoins:

  1. Purpose: Classic coins were created to improve transactions and financial systems, while memecoins are often created for entertainment purposes.
  2. Liquidity: Traditional platforms often have greater liquidity due to their financial value and large number of users.
  3. Popularity: Memecoins can quickly become popular due to viral content, but this is usually temporary.

What is the difference between the different types of cryptocurrencies?

Main Types of Cryptocurrencies: From Classic to MemecoinsStablecoins are cryptocurrencies that are pegged to fiat currencies or other assets to ensure the stability of their value. For example, USDT (Tether) is one of the most popular stablecoins. It is pegged to the US dollar and is always worth around $1. This makes it an ideal instrument for transactions where stability is important.

Unlike other types of cryptocurrencies, whose prices can fluctuate widely, stablecoins are more predictable. This makes them suitable as a means of storing and exchanging value in times of economic uncertainty.

How stablecoins work:

  1. Backing: Many stablecoins are backed by reserves of fiat currency or other cryptocurrencies, making them relatively stable.
  2. Use cases: They are often used for payments in cryptocurrency ecosystems and in decentralized finance (DeFi) applications.
  3. Transactions: Due to their stability, they are widely used for trading and as a medium of exchange on crypto exchanges.

Advantages:

  1. Stability: Unlike other cryptocurrencies that are subject to large fluctuations, stablecoins offer predictability and stability.
  2. Minimal fees: Transactions with stablecoins can be cheaper than traditional bank transfers.

Tokens and their role in the digital economy

Tokens are another important type of cryptocurrency. They differ from traditional currencies in that they are not independent currencies, but are part of a project’s ecosystem. For example, Ethereum uses tokens on its platform for a variety of purposes, from developing smart contracts to project management.

The difference between tokens and classic types of cryptocurrencies:

  1. Tokens typically exist within a project or ecosystem and can be used for various functions, such as voting, making payments, or representing assets.
  2. Blockchain: Many tokens are based on major blockchains such as Ethereum or Binance Smart Chain and can be used within smart contracts.

Examples:

  1. ERC-20 is a token standard on the Ethereum blockchain that is used to issue tokens for various projects.
  2. NFTs (non-fungible tokens) are another type of token that represent unique digital assets, such as art or collectibles.

How to choose a cryptocurrency to invest in: tips and recommendations

It is important to realize that each currency has its own role. Categorizing cryptocurrencies can help you better assess the risks and opportunities.

How to classify cryptocurrencies for investment purposes?

  1. Stablecoins: stable, suitable for storing and exchanging money.
  2. Altcoins: riskier, but also potentially profitable. These are cryptocurrencies such as Ethereum or Litecoin, which are in full development.
  3. Memcoins: inherently risky, but can suddenly increase in value in response to trends.

How to choose the right assets?

If the goal is a long-term investment, Bitcoin and Ethereum are a reliable option. However, if you are looking for more dynamic and risky assets, such as memecoins or altcoins, then you should approach them with caution. However, do not rule out the possibility of high returns.

Conclusion

How to choose a cryptocurrency to invest in: tips and recommendationsEach type of cryptocurrency comes with its own unique risks and opportunities, which directly depend on your goals. If you are looking for stability, stablecoins are the perfect option. If you are looking for exposure and quick money, memecoins can be an interesting and risky investment.
