Why Learning Crypto Terms Matters
Knowing the terms in crypto is just as important as the terms themselves. Knowing the lingo helps you navigate complex platforms. With knowledge of the words, you will be able to ask better questions and read guides more efficiently. Learning the terms is the first step in mastering crypto.
Each year, new terms and words are introduced into the crypto world. Keeping up helps you avoid being misled by outdated advice. The more up to date you are, the less likely you are to be fooled by hype. This helps you make better decisions in the crypto world. Make it a goal to learn the words as they are the foundation of every step you will take in crypto.
HODL
It is not a typo. HODL is a strategy, which means holding coins regardless of market fluctuations. This strategy is mainly used during dips and it helps the holder avoid losses. While many traders sell during a “dip”, HODLers stay calm and wait. Those that believe in the coin’s future are known as HODLers, and this strategy has helped so many avoid losses.
HODLing does demand some background scouting. You can’t just grab coins and expect results. Pay attention to the project’s fundamentals. Get to know the team. Look into the roadmap. If the foundation is strong, then holding through market madness means stepping away from your funds… and often brings long-term gains.
HODL in Action
A lot of people panicked in 2021 due to Bitcoin’s more than 50% drop in value. So, a lot of people sold. New HODLers, however, did not blink, and the markets self-corrected- Bitcoin recovered to the prices it was in 2017. With enough faith in conviction, HODLers in the 2021 market crash found 2025 to be a different story, and the 2021 HODL strategy worked wonders. Remaining calm through market crashes is essential to the long-term strategy, and emotional decision-making often leads to turmoil.
FOMO
FOMO is often the root cause of very poor trades, and in the ever-dynamic markets the world is blessed with nowadays, people no longer find patience a virtue. Action is often enforced when prices rise, as rush is a common phenomenon. Smart investors, however, know all too well to take the good with the bad. Rather, than excitedly jump, they take calculated approaches and wait for the market to stabilize.
FOMO is a one-way ticket to anguish, with both over-purchasing and under-purchasing being two consequences. People often sell as they enter, and fortune-telling and gambling trends is a common behavior we see in the market, which wipes out both dollars and self-confidence. One of the more effective and tried and tested solutions is to set up a clear, actionable plan and ignore publicity.
Do Your Own Research
Do Your Own Research (or DYOR) means that before you put your money anywhere, you need to research things on your own. It might seem simple, but it saves you money. You cannot just trust an influencer, or a viral post on social media. You need to read the coin’s white papers. Look at the company’s team. Research how they are using the coin, and how the community is involved. You need to follow this rule if you want to be a successful investor.
Thorough research protects you from scams. Many projects try to get attention by using buzz words. If something looks too good, then you need to be extra careful. Verify the tokenomics, total supply, and partnerships. With DYOR, you can turn the hype and truths on its head.
Blockchain
Blockchain is the essence of crypto. It is a digital ledger that contains all transactions. Each record is locked and can be accessed by everyone. This is how you build trust. There is no single authority that has control. The reason why many industries are looking into blockchain now is that they want to use it for more than just money.
Every block is linked to the previous one, which forms a chain. Once data is linked, no one can alter it. This makes fraud almost impossible. Blockchain makes it possible to have secure and fair digital systems for different industries like finance and voting.
Wallet
A crypto wallet is a program that safeguards your digital assets. It Functions similar to a bank account, but unlike a bank, you control the keys. There are two main types hot and cold. Each has its benefits. Hot wallets offer speed. Cold wallets provide security. It all depends on what you want to achieve.
Hot wallets are great for beginners. They are mobile applications or extensions to a browser. They enable you to send and receive crypto in record time. But if the amount involved is sizable, cold wallets are much better. They keep the keys to your crypto stored offline, preventing hackers from gaining access and ensuring that your funds are safe.
Public and Private Keys
These keys are critical. Public keys are like emails and can send you funds which is great. But, Private keys are akin to passwords and should not be shared. Sharing it will result in someone taking control of your crypto. Always store it safely and never post it on social media.
Most wallets automatically generate and store keys for you which is very helpful. But you should still back up the seed phrase. It is important to write it on paper and keep it somewhere safe. Without it, you will not be able to recover your wallet and in the crypto world, keys are absolute. Always ensure that you treat them well.
NFT
NFTs are virtual collectibles where each token is one of a kind. They can be in the form of art, music, or game assets. By the year 2025, NFTs will be p able to manage identity, ticketing, and other virtual items. NFTs are loved by creators since they enable direct transactions. Furthermore, fans are able to possess ownership of treasured digital items.
NFTs bring added value such as giving fans access to events or unlocking other special content. They also have added value in the form of tracking supplies and tracking brand engagement. As more people shift toward the digital world, NFTs will see increasing demand.
DeFi
DeFi lets you lend, trade, and borrow without the involvement of a bank. This is made possible through smart contracts. By 2025, DeFi apps will be able to better traditional finance in terms of services. Anyone with a phone will be able gain access to a world of finance. Unlike banks, there is no paperwork or credit check required.
Open DeFi is one of the most crucial reasons it keeps growing. Anyone is able to create tools to be used by other people. Unfortunately, this also brings a risk. Under risk comes the need to do audits on contracts. Always start with small amounts. While the freedom DeFi brings is great, it is the level of caution you exercise that keeps you safe.
Smart contracts
Smart contracts are the fully automated programs that contracts are divided into. They run on the “if this, then that” rule. If you send a form of cryptocurrency, a form of a reward can be sent back. This is fully automated without a human touching the contract. By the year 2025, smart contracts will be able to run a wide variety of applications such as games and loans.
Cutting out middlemen means lower costs, but errors can lead to massive losses. Make sure to audit smart contracts, or checks done before a process starts, because having verified contracts allows you to trust the process.
Gas Fees
Gas, the price you pay to send coins or run contracts, functions as blockchain fees. Some blockchains are more expensive than others. Ethereum’s gas fees, for example, remain high during busy hours but are reduced by Layer 2 solutions.
You can strategically execute transactions during low-fee windows, which are trackable via Etherscan. Selecting less expensive chains, such as Solana or Arbitrum, works as well. Plan how to send crypto to prevent additional surprise fees.
Stablecoin
Real-world currencies back stablecoins. Popular options include USDT, USDC, and DAI. Use them to protect funds from losing value. Traders often convert funds into stablecoins during bear markets to remain prepared for new purchases.
Stablecoins offer quick and cheap transfers, and are beloved by businesses. In 2025, some countries will even rely on them for cross-border payments. They merge the quickness of blockchain with the trust crypto provides.

Altcoin
Altcoins are any cryptocurrency that is not Bitcoin. The top altcoins are Ethereum, Solana, and Avalanche. Many altcoins attempt to improve upon Bitcoin’s limitations. Some altcoins are faster than Bitcoin, others provide smart contracts, and some provide much lower fees. Each altcoin comes with different features, and studying them can help you find the hidden gems.
The altcoins differ in levels of risks, and you should always try to stick to altcoins that have a genuine problem to solve. Check developer activity and try to read the whitepapers. If a coin can provide the strong use and adoption, it is bound to face success.
Tokenomics
Tokenomics is the combination of “token” and “economics”. It explains a token’s functioning and covers its supply, burn rate, and distribution. A coin with poor tokenomics might inflate, hurting holders. Good tokenomics focus on long-term growth and support them by balancing scarcity and utility.
Bad tokenomics can result in a lack of trust and poor performance in the coin over a period. Study the charts and supply plans, and see what the tokenomics of the coin is. If developers or insiders hold too many coins, it creates a lack of trust.
Whitepaper
A whitepaper is the blueprint. It explains the project, use case, and future plans. Good projects have whitepapers. Reading it can help you gather their level of understanding. If you find vague or copied whitepapers, the project should be skipped.
Look for clear goals, good team bios, use cases, tokenomics. And strong whitepapers will always show a good project timeline. Make it a good habit to review the whitepaper of the project you want to invest in before any investment.
DApp
DApps are an abbreviation for decentralized applications. Unlike other applications, they operate on a blockchain. They do not have a singular owner. Examples of such applications are wallets, games, and trading tools. By 2025, DApps will have taken over DeFi, NFTs, and Web3.
DApps are used alongside wallets such as MetaMask. They allow users to trade, earn, or play without relinquishing control. Always read reviews before using a DApp. Some fraudulent copies exist and these attempt to steal funds.
Rug Pull
Rug pulls are a type of exit scam. The “team” creates hype for a coin and then drains liquidity, disappearing without a trace. You will lose money. Rug pulls will still be rampant in 2025. Knowing how to spot them will relieve you of unnecessary pain. Always check if a project has audits and lock-in liquidity.
Never forget to study the team. Do they display their faces and past work? If everything feels anonymous or rushed, it’s likely a trap. Follow your instincts and Do Your Own Research.
Liquidity
Liquidity measures the ease of purchasing or selling a coin. High liquidity allows fast trades at good prices. With low liquidity, there is a lot of trading volume which can greatly change the price. You can experience the loss of value while purchasing or selling.
Always check liquidity of exchanges. Take advantage of platforms with deep pools. This will result in smoother trades. Unless you are prepared to face the volatility, avoid coins with tiny markets.
DAO
DAOs allow for communities to manage projects. You hold a token, and you get a vote. Everyone decides on the changes. Smart contracts enforce the rules. In 2025, DAOs will manage art and investments, as well as everything in between.
Joining a DAO means shared control. Read the rules first, though. Some DAOs have unclear overarching objectives. Others suffer from poor coding. Regardless, the impact and possibilities on how blockchain changes and improves project governance are staggering.
Proof of Work vs Proof of Stake
Blockchains require these systems to authenticate transactions. Proof of Work (PoW) requires mining power. Bitcoin uses it. It’s secure but has a heavy trade off in energy consumption. Proof of Stake (PoS) is faster and greener. Ethereum has now switched to PoS. PoS rewards validators who lock in their coins as validators.
POW is still active, however, it is expected to lose value by 2025 PoS is now being regarded as the primary standard. It improves energy efficiency and accelerates block creation. Some networks still find PoW useful. However, PoS is attractive for eco-friendly investors. Always check what system your coins operate on, as it since it impacts transaction speed and transaction fees.
Hash Rate
Hash Rate illustrates the strength in the blockchain’s miners. With a higher hashrate the level of security improves. It becomes harder for hackers to attack. At the moment bitcoin has the highest hashrate. When have a hash rate low, the networks are at risk on being attacked. So miners are really important.
Mining rewards are directly impacted by hash rate. Increased power comes with increased chances to validate blocks. Also remember to check the hash rate because it impacts your mining strategy and what hardware you choose.
Airdrop
Airdrop gives you free tokens. Projects do them for marketing. You might qualify by holding a certain coin or performing basic tasks. Some airdrops reward loyal customers, while others promote new DApps or Layer 2 chains.
But watch out. Some airdrops are scams. Never share private keys. Stick to trusted projects. Always do research before claiming any airdrop.
In 2025, popular airdrop activities include:
- Holding tokens like ETH or SOL
- Taking quizzes on launchpads
- Referring others to new platforms
ICO, IDO, IEO
These are ways to launch tokens. ICOs sell directly to the public. IDO’s launch on decentralized platforms while IEO’s go through exchanges. Each has pros and risks. In 2025, IDO’s lead due to fast launches and DeFi growth.
Investors love early-stage tokens, but they’re high-risk. Read the whitepaper. Understand vesting periods and check for lock-ins. Properly done, these events offer high returns.
Market Cap
Market cap tells a coin’s size. It’s price × total supply. Big market caps, like Bitcoin, are safer. Small caps can offer bigger returns—but with more risk. Study market cap to spot trends and manage your investment balance.
Utilize it to evaluate coins. Avoid chasing price. If a coin has a supply of billions, it’s not worth a mere $0.01. Focus on value, not what’s popular.
Bull Market vs Bear Market
Cryptocurrency markets oscillate between bull and bear periods. Bull markets bring growth and hype. Coins can be doubled in no time. Bear markets bring fear and a tendency to crash. Knowing where you are in the market can shape your strategy.
In 2025, it is expected to be a build during bear market period. Buy when it’s cheap, and HODL. It’s a guaranteed strategy where you stand to gain the most during the bull market. Don’t try to make a playing decision off a swiftly rising price. Plan ahead when prices are low.
Whale
Whales are known to hold large volumes of cryptocurrency. Their trades are market movers. Token price crashes happen when a whale sells. Price is increased when they purchase. In 2025, whale tracking tools are expected to be able to show on-chain movement in real time. Following them is called smart trading.
Watch out the whale wallets. Track their wallets with Whale Alert or Nansen. If they decide to invest in a particular coin, it may mean they consider it a strong project, but don’t be a fool and follow blindly. Always add your personal research to this data.
Degen
Degens are generally known to be the risky type of investors. They invest in the new projects with little to no hype. They can either win big, or completely take a loss. It’s all about moving fast and taking the plunge. In 2025, many fast hype cycles are expected to attract degens.
If you’re going to act like a degen, set limits and lower your spending. Don’t go broke chasing after degen life—although there’s a thrill, there’s also a world of hurt. Be smart about the choices you make.
Application of the Terms
To illustrate these terms, let’s assume you join a DApp that’s giving away an airdrop. You connect your hot wallet, pay the gas fees, and the smart contract verifies your wallet, so you get the tokens. You check the whitepaper and decide to HODL on the altcoin.
At that point, you have made use of:
- Wallets and smart contracts
- Airdrops and gas fees
- HODLing without doing your research first
Each of these terms may seem like nonsense but they capture the essence of how the cryptocurrency world operates.
