Cryptocurrency is a digital currency with all the features of money initially designed to be decentralized (not controlled by a central authority like a government or bank) and secure through the use of cryptographic encryption, which ensures security. The crypto transactions are associated with random strings, which enhance privacy, and are based on technology known as blockchain.
A blockchain is a digitally distributed, decentralized, public ledger connected to a network of computers. It is a new technology that is associated with cryptocurrency, but its use has expanded to other industries like finance, health, law, and real estate.
But did cryptocurrency start recently?
Nope.
The crypto journey started way back in 1983 when David Chaum, a cryptographer, published a paper titled “Blind Signatures for Untraceable Payments.” Since then there have been developments that led to the creation of Bitcoin in around late 2008, which is well known to be the first cryptocurrency of the modern day.
In January 2009, the first Bitcoin transaction took place between Satoshi and cryptographer Hal Finney; they were the pioneers of Bitcoin mining. However, the first real-world Bitcoin transaction occurred on May 22, 2010, when Laszlo Hanyecz spent 10,000 BTC to have two Papa John’s pizzas delivered, valued at approximately $41, which is referred to as Bitcoin Pizza Day by crypto enthusiasts.
How does cryptocurrency work?
Cryptocurrency adoption is increasing globally, and therefore knowing how it works is important, as it is projected to replace money. Many institutions, including banks, now accept crypto. JP Morgan Chase, for example, which is one of the largest banks in the world, has invested in Bitcoin ETFs. BlackRock, being the largest investment company in the world, currently holds over 567,000 Bitcoin and a total of 1,352,934 Ethereum.
As the major institutions continue to integrate crypto as part of investment and accept it for the purchase of goods and services, the demand and value of cryptocurrencies will rise, and its use as well.
To use cryptocurrency, you will need to understand how blockchain technology works, as this is the core technology driving the crypto market. Here are the basic things you need to understand while engaging in crypto transactions.
- You need a crypto wallet to be able to send or receive crypto assets. Examples of some of the common wallets include Binance Web3 Wallet, Coinbase Wallet, MetaMask, Zengo, Exodus, etc. To learn more, you can check the top 5 tools you need as a crypto user
- You need a cryptocurrency exchange where you can buy or sell crypto assets. This is where trading takes place. The common exchanges are Binance, Bybit, Coinbase, Gate.io, etc.
- You have to do your own research about the cryptocurrencies you need to purchase because there are a lot of scams and rug pulls in the crypto market. To start with and to ensure your safety, stick to buying only established cryptos like Bitcoin and Ethereum as a beginner. As you become experienced, you can now consider the other crypto assets.
The reason why cryptocurrencies are immutable is because of blockchain technology. This technology makes it almost impossible to hack. For instance, to hack the Bitcoin network, you need to control more than 50% of it. Which is practically hard given the popularity and valuation of Bitcoin. In a blockchain network, everyone can see transactions, the pseudonymous addresses involved, and the amount transferred.
However, these public ledgers do not allow anyone to access them and submit or change entries; this is done automatically by scripts, programming, encryption techniques, and an automated transaction validation process. Cryptographic techniques are used to issue, verify, and secure transactions.
Through public ledgers, transactions remain traceable and unable to be counterfeited. This peer-to-peer digital asset system makes it fast, easy, and cheap to send and receive payments worldwide. There’s no currency exchange needed, nor are there hefty fees. Transactions using these financial assets are publicly recorded, stored digitally, and transmitted by encryption, with detailed coding required for transmission and storage.
But wait… If blockchains are supposed to be unhackable, then why do scams and rug pulls still happen?
Crazy, right? It’s one of the most misunderstood things in crypto—and it’s exactly how thousands get wrecked every day. Let’s break it down.
Scams and rug pulls happen outside the blockchain. For example, the biggest crypto heist in history so far, where Bybit lost $1.4 billion of Ethereum, was due to exploitation by the hackers of vulnerabilities in the user interface (UI) application. The attackers, commonly known as North Korea’s Lazarus Group, introduce a malicious JavaScript code to trick the signers into believing that what they are signing is what they intended. What they didn’t know is that they were handing over their Ethereum assets to hackers.
How exactly did they do it?
- First they studied both the infrastructure of Bybit and Safe (it provides management of digital assets through multisignature technology to Bybit) and identify a gap
- Then they created a malicious code that will only be activated once Safe interacts with the Bybit contract address.
- Once the mission was successfully executed, they remove the malicious code to avoid suspicion and transfer the Ethereum to different addresses and subsequently convert them to Bitcoin and other cryptos. They then disappear into thin air
All these occur off-chain.
The most common scam, though, according to the FBI, is pig butchering, where scammers build trust with victims over time, often through romance or social networking, and then convince them to invest in fake crypto platforms. Others include phishing, impersonation, investment group scams, fake ICOs, rug pulls, liquidity mining/yield farming scams, and crypto giveaways/airdrops.
Other elements that set cryptocurrency apart from more traditional investments include
-
Accessibility. Cryptocurrency investing is open to anyone with internet access and a computer, smartphone, or mobile device.
-
Low transaction. Cryptocurrency blockchain transactions cost no more than a few dollars, with many costing just pennies.
-
Faster Transaction. Some cryptocurrencies process the transactions faster compared to other payment systems.
What is cryptocurrency mining?
Mining is the process that Bitcoin and some other cryptocurrencies use to generate new crypto and verify new transactions before being added to the blockchain. It usually involves several decentralized networks of computers around the globe that verify and secure blockchains. The participants are in turn rewarded for contributing their processing power with new coins. The blockchain system is designed in a way that the miners maintain and secure it, and the blockchain awards the coins, which act as an incentive for the miners to maintain the blockchain.
How does cryptocurrency mining work?
Each block on the blockchain has a mathematical puzzle within it, which miners must solve before being awarded some coins as a reward. Crypto miners compete to solve the puzzle, and the first one to solve it is the one who will be awarded. They use specialized, high-energy computers. The two main types of hardware used in Bitcoin mining are GPUs (graphics processing units) and ASICs (Application-Specific Integrated Circuits). Each has its advantages, but ASICs dominate the scene due to their specialized design. These computers use trial and error, guessing repeatedly until they find a solution. The one that finds a solution is awarded.
Top 10 cryptocurrencies by market cap
- Bitcoin
Bitcoin is a decentralized cryptocurrency originally described in a late 2008 white paper by a person, or group of people, using the name Satoshi Nakamoto. It was launched soon after, on January 3, 2009.
Bitcoin is a peer-to-peer online currency, meaning that all transactions happen directly between equal, independent network participants, without the need for any intermediary to permit or facilitate them. Bitcoin was created, according to Nakamoto, to allow online payments to be sent directly from one party to another without going through a financial institution.
Some concepts for a similar type of decentralized electronic currency precede BTC, but Bitcoin holds the distinction of being the first-ever cryptocurrency to come into actual use.
2. Ethereum
Ethereum is a decentralized open-source blockchain system with its own cryptocurrency known as Ether. ETH acts as a platform for numerous other cryptocurrencies, as well as for the execution of decentralized smart contracts.
Ethereum was first described in a 2013 whitepaper by Vitalik Buterin. Buterin, along with other co-founders, secured funding for the project in an online public crowd sale in the summer of 2014. The project team managed to raise $18.3 million in Bitcoin, and Ethereum’s price in the Initial Coin Offering (ICO) was $0.311, with over 60 million Ether sold. Taking Ethereum’s price now, this puts the return on investment (ROI) at an annualized rate of over 97%.
The Ethereum Foundation officially launched the blockchain on July 30, 2015, under the prototype codenamed “Frontier.” Since then, there have been several network updates — “Constantinople” on Feb. 28, 2019, “Istanbul” on Dec. 8, 2019, “Muir Glacier” on Jan. 2, 2020, “Berlin” on April 14, 2021, and most recently on Aug. 5, 2021, the “London” hard fork.
3. Tether
Launched in 2014, Tether is a blockchain-enabled platform designed to facilitate the use of fiat currencies in a digital way. Tether aims to disrupt the traditional financial system through a more modern approach to money. Tether has changed the way we do transactions by giving customers the ability to transact with traditional currencies across the blockchain, without the inherent volatility and complexity typically associated with crypto.
4. XRP
Launched in 2012, the XRP Ledger (XRPL) is an open-source, permissionless and decentralized protocol. Benefits of the XRP Ledger include that it is low-cost ($0.0002 to transact), quick (settling transactions in 3-5 seconds), scalable (1,500 transactions per second) and also green by nature (carbon-neutral and energy-efficient). The XRP Ledger also boasts the first decentralized exchange (DEX) and custom tokenization as part of the protocol. The XRP Ledger has been continuously operating since 2012, having closed 70 million ledgers
5. BNB
Binance Coin (BNB) is a cryptocurrency that can be used to trade and pay fees on the Binance cryptocurrency exchange. Founded in July 2017, Binance is the world’s largest cryptocurrency exchange by daily trading volume. Binance aims to bring cryptocurrency exchanges into the mainstream of worldwide financial activity. The inspiration for the name Binance came from the desire to capture this new chapter in world finance — Binary Finance, or Binance
6. Solana
Solana is a highly functional open source project that is based on the permissionless nature of blockchain technology to provide decentralized finance (DeFi) solutions. According to the Solana whitepaper, while the idea and initial development of the project began in 2017, Solana was officially launched in March 2020 by the Geneva, Switzerland-based Solana Foundation.
7. USDC
USDC is a stablecoin that is pegged to the dollar, and every unit of this cryptocurrency that is in existence has an equivalent $1 reserve held by the Centre consortium, in cash as well as in short-term U.S. Treasuries. The Centre consortium, being the owner of this asset, asserts that USDC is issued by regulated institutions.
8. Dogecoin
Dogecoin (DOGE) is based on the widely used “doge” Internet meme and features a Shiba Inu on its logo. The peer–to-peer cryptocurrency was created by Portland, Oregon‘s Billy Markus and Sydney, Australia‘s Jackson Palmer and forked from Litecoin in December 2013. Dogecoin’s creators imagined the cryptocurrency as a light-hearted, humorous altcoin that would be more successful outside of the primary Bitcoin market, because it was based on a dog meme. Tesla CEO Elon Musk tweeted repeatedly on social media saying Dogecoin is his favorite coin
9. TRON
TRON (TRX) is a decentralized blockchain-based operating system developed by the Tron Foundation and launched in 2017. Originally TRX tokens were ERC-20-based tokens deployed on Ethereum, but a year later they were moved to their own network.
10. Cardano (ADA)
Cardano is a proof-of-stake blockchain platform that says its goal is to allow “changemakers, innovators and visionaries” to bring about positive global change

How to buy cryptocurrency
To buy crypto as a beginner you can either use crypto exchange or purchase in payment app however you need to have a wallet where you can store your coins. Here are the steps on how to buy cryptocurrency as a beginner;
- Do your own research about the crypto you want to purchase
- Sign up with an exchange which offers that type of coin you have chosen
- Choose the type of wallet you want to use whether it is hot wallet or cold wallet. Cold wallet is the best for long term storage of your assets because it is safer that way however if you will be using it regularly then you can store it in a hot wallet with high reputaion like Metamask
- Make sure you store your private keys safely to make sure they don’t get lost or stolen
- Keep monitoring your crypto assets to ensure they are safe
What can you buy with cryptocurrency?
As the adoption of crypto spread widely its acceptance for purchase of goods and services is increasing as well. Many companies have join the likes of Tesla in accepting cryptocurrency. Example of what crypto can buy include;
- Cars: The list includes Lamborghinis, and electric car maker Tesla has joined the list of firms that enable you to purchase cars with cryptocurrency. Tesla CEO and X Corp owner Elon Musk is cryptocurrency-friendly.
- Technology and E-commerce Items: Some retailers of technology products do accept cryptocurrency, including Newegg, Namecheap, AT&T, and Microsoft. Other sites, including Shopify and the Japanese e-commerce firm Rakuten, allow you to purchase items with Bitcoin. PayPal has integrated cryptocurrency into its platform, enabling users to buy, sell, and store Bitcoin along with other digital currencie. Richard Branson’s company, which includes Virgin Mobile and Virgin Airlines, allows you to pay for space travel with Bitcoin
- Jewelry and Watches: Luxury e-commerce retailer BitDials offers Rolex, Patek Philippe, and other high-end watches for Bitcoin and other digital currencies. Luxury watchmaker Franck Muller created a gold- and diamond-covered watch that has embedded within it a QR code from the Bitcoin Genesis Block.
- News Media: Magazine publisher Time Inc. began accepting online subscription payments in cryptocurrency in 2014. Magazine publisher Time Inc. established a new cryptocurrency partnership with Crypto.com in 2019.
- Insurance: In April 2021, Swiss insurance company AXA began accepting cryptocurrency as a mode of payment for all types of insurance except life insurance. Insurance agency Metromile, which sells “pay-per-mile” auto insurance policies, also accepts Bitcoin as a method of payment for premiums
- Food : Through the Bakkt payment platform, Starbucks allows customers to use Bitcoin to reload their Starbucks cards via the app, enabling indirect purchases of coffee and other items with cryptocurrency. Burger King outlets in Venezuela announced a partnership with Cryptobuyer to accept cryptocurrencies as payments. Customers can pay in Bitcoin, Dash, Litecoin, Ethereum, and Tether. Chipotle— Accepts over 98 cryptocurrencies through its partnership with Flexa, which makes it a crypto-friendly restaurant.
Is cryptocurrency safe to invest ?
Despite the volatility associated with crypto many investors have profited with some making millions of dollars by just investing small amount of money. If we have to consider the time cryptocurrency has existed in the market since 2009 and its core technology blockchain, we can conclude that crypto is a good investment for investors who are ready to do their reasearch and take risk.
However, what you need to know is that investment in cryptocurrency is risky and is normally very speculative, not a secure investment. Although the blockchain technology upon which it is based has some security aspects, cryptocurrency exchanges and wallets can be hacked, subject to fraud, and theft. Cryptocurrencies’ values can also change rapidly based on market sentiment and popular opinion, thereby resulting in massive losses
Ways to invest in crypto
There are several ways to invest in cryptocurrency the common methods include;
1. Buy crypto directly.
In order to buy crypto directly, you will need to use a cryptocurrency exchange website, such as Bybit which is the second largest exchange in trade volume. You can sign up here for Bybit. Coinbase and Robinhood are also among the top. To do this, you sign up with the site and fill out a verification process. Once this is done, you are able to link your bank account and buy your crypto.
2. Mine crypto.
Cryptocurrency mining is the method of “digging up” new crypto coins by solving mathematical problems and verifying blockchain transactions. To mine cryptocurrency, you will likely need to go through a verification process and buy mining software and hardware.
3. Invest in crypto-related stocks.
Investing in crypto-related companies, such as Robinhood Markets, Inc., is also a way to invest your funds in the cryptocurrency market. Buying shares of such companies allows you to indirectly invest in cryptocurrency.
4. Invest in blockchain ETFs.
Just like investing in the stocks of cryptos, when you are investing in a blockchain exchange-traded fund, you will be investing in companies that facilitate cryptocurrency rather than the actual coins. Blockchain ETFs will have a variety of companies from companies that are involved in developing and maintaining the blockchain to companies that directly gain from the blockchain system.
5. Invest in a crypto IRA
A crypto IRA gives you access to the tax advantages of an IRA but lets you invest in cryptocurrency. You cannot deposit crypto into the IRA, so you will have to get a custodian that will accept crypto.
6. Staking your crypto
Cryptocurrency staking involves your holding and locking your digital assets on a blockchain network to assist it in validating transactions and earning rewards. In recompense for your participation, the network rewards you with additional cryptocurrency. It is very similar to earning interest on a savings account, except with the potential for higher returns and the attendant risks
7. Using your crypto assets to give loans
Cryptocurrency lending is a financial transaction where one party gives cryptocurrency to another party for compensation. It is identical to traditional lending but, in contrast to bank-based lending, crypto lending is conducted via crypto lending platforms. These platforms can be centralized or decentralized with different benefits and risks.
8. Yield farming
Cryptocurrency yield farming or liquidity mining is an approach where users stake or lend their virtual tokens in decentralized finance (DeFi) systems to earn rewards, such as interest or additional tokens. It’s a way of enabling those who own cryptocurrency to make passive income through lending liquidity to DeFi platforms
9. Crypto arbitrage trading
Cryptocurrency arbitrage trading is a strategy that attempts to take advantage of price disparities in the cryptocurrency market. It involves purchasing a digital asset at a lower price in one market and selling it at a higher price in another. It is not a new or novel strategy in the crypto market; it is a standard practice in traditional financial markets as well.
Speed is the most crucial factor in crypto arbitrage trading. Cryptocurrency prices fluctuate every second, and the price can drop or rise at any moment. Therefore, the most critical aspect of conducting cryptocurrency arbitrage is being watchful and quick. The goal is to utilize the price difference before it no longer exists.
What are the pros and cons of cryptocurrency?
Since the invention of cryptocurrency the financial industry has undergone a tremendous transformation although with some challenges as well.
Benefits of Cryptocurrency
1. Decentralization and Control
Cryptocurrencies operate on decentralized networks such as blockchain, as opposed to traditional currencies. It means they are not regulated by any central bank or government. Users have more control over their money, reducing the likelihood of interference or inflation due to improper monetary policies.
2. Transparency and Security
Most blockchain transactions are publicly verifiable and immutable. Such transparency reduces fraud and enhances trust. Further, advanced cryptographic protocols make transactions secure, especially when compared to traditional systems that are vulnerable to hacks and data breaches.
3. Financial Inclusion
Cryptocurrencies facilitate access to financial services for unbanked or underbanked populations worldwide. Anyone with an internet connection and a smartphone can participate, reducing the dependence on traditional banking infrastructure.
4. Low Transaction Costs and Speed
Cryptocurrency transactions—especially cross-border—are usually faster and cheaper than remittance services or banks. Exchanges like Solana or Stellar process thousands of transactions per second for a fraction of the cost of traditional methods.
5. High Return Potential
The majority of investors are drawn to cryptocurrencies because of their high return potential. Cryptocurrencies like Bitcoin and Ethereum have experienced huge growth since inception, and early adopters and investors have become rich.
6. Innovation and Smart Contracts
Platforms like Ethereum enable smart contracts, which enable decentralized applications (dApps) and DeFi (Decentralized Finance). These innovations are changing how people lend, borrow, invest, and trade—without intermediaries.
Disadvantages of Cryptocurrency
1. Volatility
The prices of cryptocurrencies are extremely volatile. A coin’s value can double or implode within hours depending on news, regulation, or investor sentiment. This makes crypto a risky investment and not ideal for conservative investors or everyday transactions.
2. Lack of Regulation
Crypto’s decentralization is both a strength and a weakness. In the majority of countries, there are limited regulations or legal recourse for crypto users. This provides space for scams, fraud, and market manipulation.
3. Security Risks and Scams
While blockchains themselves are secure, exchanges, wallets, and individual users are regularly targeted. Phishing attacks, rug pulls, Ponzi schemes, and phantom tokens are common threats, especially to new investors.
4. Environmental Impact
Environmental Concerns
Some cryptocurrencies, like Bitcoin, use energy-intensive proof-of-work (PoW) mining algorithms. This has challenged the environmental sustainability of crypto, even though alternatives like proof-of-stake (PoS) are gaining popularity.
5. Limited Adoption and Usability
Despite growing popularity, the adoption of crypto for everyday use is low. There are few merchants who accept crypto directly, and it may be difficult or costly to switch between crypto and fiat.
6. Irreversibility and Human Error
Cryptocurrency transactions are irreversible. If you send funds to the wrong address or get defrauded, in most instances, there is no recovering your money—unlike with banks or credit card providers.
The difference between coins and tokens
The difference between coins and tokens in cryptocurrency comes down to their blockchain origin and use cases. Here’s a simple breakdown:
Coins
Definition:
Coins are digital currencies that operate on their own native blockchain.
Examples:
- Bitcoin (BTC) → runs on the Bitcoin blockchain
- Ethereum (ETH) → runs on the Ethereum blockchain
- Solana (SOL) → runs on the Solana blockchain
Key Features:
- Used primarily as money or store of value
- Can pay transaction/gas fees on their network
- Typically help secure the network (e.g., via mining or staking)
Tokens
Definition:
Tokens are digital assets built on top of an existing blockchain, using that chain’s infrastructure.
Examples:
- USDT, Chainlink (LINK), and Uniswap (UNI) are tokens on Ethereum
- SRM is a token on Solana
Key Features:
- Used for specific applications, like DeFi, NFTs, games, voting, etc.
- Created with smart contracts (e.g., ERC-20, BEP-20 standards)
- Don’t run on their own blockchain, but depend on another’s
In Simple Terms:
- Coin = native to its own blockchain
- Token = lives on someone else’s blockchain
Common Terms used in cryptocurrency
The cryptocurrency world can be tricky to navigate through, especially when it feels like everyone is speaking a different language.
Learn some of the most common terms and expressions used in the blockchain and cryptocurrency industry today
Altcoin
An Altcoin is an alternative digital currency to Bitcoin.
The word Altcoin resulted from joining of the words “alternative” and “coin”, to form “altcoin”. It actually refers to a group of cryptocurrencies, ultimately all the cryptocurrencies other than Bitcoin.
Stable Coins
Stablecoins are a type of cryptocurrency designed to maintain a stable value by being pegged to a reserve asset, usually a fiat currency like the US Dollar, Euro, or even commodities like gold.
Key Features of Stablecoins:
- Price Stability
Unlike Bitcoin or Ethereum, which can be volatile, stablecoins aim to stay steady—e.g., 1 USDT ≈ 1 USD. - Global & Borderless
Like other cryptocurrencies, they can be sent globally, instantly, and 24/7. - Use in DeFi & Trading
Widely used in crypto trading, lending, saving, and payments—offering a “safe haven” during market volatility.
Types of Stablecoins
Fiat-Backed Stablecoins
Backed 1:1 by actual fiat money stored in banks.
Examples: USDT (Tether), USDC (USD Coin), BUSD
Features
- Simple but trusted
- Needs central custody (not fully decentralized)
Crypto-Backed Stablecoins
Backed by cryptocurrencies like ETH or BTC held in smart contracts.
Examples: DAI (by MakerDAO)
Features
- More decentralized
- Complex, can become undercollateralized during crashes
Algorithmic Stablecoins
Use algorithms to control supply & demand to keep price stable.
Examples: (Terra) UST — now infamous for its collapse
Features
- No collateral needed
- Very risky if confidence drop
Commodity-Backed Stablecoins
Backed by physical assets like gold or oil.
Examples: PAXG (gold-backed)
Features
- Tied to real-world value
- Less liquid, more storage complexity
Why Are Stablecoins Important?
- Offer price stability in volatile crypto markets
- Enable fast, cheap international payments
- Used for DeFi applications (like lending/borrowing)
- Bridge between crypto and traditional finance
Meme coins
Meme coins are altcoins (alternative cryptocurrencies that are not Bitcoin) that are assigned names on the basis of trends, humorous or goofy objects, or anything else imaginable. They are usually made to encourage people to join a group and are viable in peer-to-peer transactions, speculative investment, or trading. They are usually accompanied by websites with humorous themes, sometimes absurd terms, and the creators of these and their supporters sell a belonging sense in order to attract other individuals.
Dogecoin, Shiba Inu, and Pepe are generally the most popular meme coins
Node
For blockchain and cryptocurrency, a node is a computer or device that participates in a blockchain network. It runs the blockchain software and assists in transaction verification, the maintenance of the distributed ledger, and network security and decentralization. Nodes are essentially the pillars of a blockchain, enabling it to function as a secure and distributed network
Timestamp
The timestamp is a small piece of data that exists in each block as a series of unique and whose sole function is to give a specific time when the block has been mined and verified by the blockchain network
Atomic swaps
Atomic swaps provide peer-to-peer exchange of crypto tokens between separate blockchain networks that only occur if both sides deposit a predetermined number of tokens in the exchange contract. This enables any two individuals to trade digital tokens without trusting a third party to cause this to occur—thereby reducing counterparty risks.
ICO
An initial coin offering (ICO) is the cryptocurrency market’s equivalent of an initial public offering (IPO). A company that wishes to raise funding to create a new blockchain application or service with a cryptocurrency can issue an ICO as a way of raising funding.
Interested investors can buy an initial coin offering to receive a new cryptocurrency from the company. The token can have some utility that relates to the product or service that the company is offering or be a representative of ownership in the company or project.
Full clients
A full client in cryptocurrency, or a full node, is a computer program that downloads and stores the entire blockchain and validates transactions and blocks according to the network protocol. Full clients bring integrity and security to the cryptocurrency network by verifying the validity of each transaction and block personally, regardless of third-party services
Lightweight clients
This is a software that download only a sectipn of blockchain
Conclusion
Cryptocurrency is no longer a buzzword—it’s a revolutionary tech redefining how we know money, ownership, and financial freedom. From the understanding of how blockchain works to safekeeping your holdings, you’ve now read the essentials that every beginner must know in 2025. Whether you’re looking to invest, trade, build on decentralized networks, or just stay in the loop, crypto offers real opportunities—but only to those who take the time to learn and stay updated.
