The crypto sector is constantly evolving. New blockchains, digital payment methods, trading strategies, and financial technologies frequently give rise to new terminology.

That is why we have compiled this crypto glossary. Here, you will find commonly used terms, technical concepts, and abbreviations from the world of crypto.

PART 1 — Common Crypto Terms

1. Cryptocurrency (crypto)

A digital form of value that uses cryptography to secure transactions. Cryptocurrencies can be used for purposes such as making payments, storing value, or accessing specific blockchain functionalities.
Examples: Bitcoin (BTC), Ether (ETH), and TRON (TRX).

2. Altcoin

Any cryptocurrency other than Bitcoin. The term is traditionally used for other cryptocurrencies, though some users also include tokens under this label.
Examples: ETH, ADA, and LTC.

3. ATH (All-Time High)

The highest price a cryptocurrency has ever reached on a given market or trading platform.

4. ATL (All-Time Low)

The lowest price ever recorded for a cryptocurrency on a given market or trading platform.

5. Bear Market

A period during which the prices of financial assets decline over an extended time, and market sentiment is predominantly negative.

6. Bull Market

A period during which the prices of financial assets are generally rising and market sentiment is positive.

7. Blockchain

A digital ledger in which transactions are recorded in blocks and cryptographically linked together. Depending on the network, participants can verify transactions without relying on a single central authority.

8. Coin

A digital currency that operates on its own blockchain.
Examples: BTC on Bitcoin, ETH on Ethereum, and TRX on TRON.

9. Token

A digital asset issued on an existing blockchain. Tokens can, for instance, represent a payment function, a right of use, voting rights, or a financial interest.
Examples: USDT on Ethereum and Suredcu (SRDC) on Ethereum.

10. Fiat Currency

Traditional money issued by a government or designated as an official currency.
Examples: the Surinamese dollar (SRD), the US dollar (USD), and the euro (EUR).

11. Market Cap (Market Capitalization)

The estimated total market value of the circulating supply of a cryptocurrency.
Calculation: current market price × circulating supply.
A high market capitalization does not automatically mean that a cryptocurrency is safe, stable, or easily tradable.

12. Liquidity

The extent to which an asset can be quickly bought or sold without the transaction significantly affecting its market price.

13. Volatility

The degree to which the price of an asset fluctuates. The value of cryptocurrencies can rise or fall sharply within short periods. ### 14. HODL
Crypto slang for holding onto cryptocurrency for a long period instead of selling it. The term originated as a misspelling of the word "hold."

15. FOMO (Fear of Missing Out)

The fear of missing out on an opportunity for profit. This can lead people to impulsively buy cryptocurrency when prices have already risen significantly.

16. FUD (Fear, Uncertainty and Doubt)

Fear, uncertainty, and doubt that can negatively influence the perception of a project or market. The term is also used when incorrect or misleading information is spread.

17. DYOR (Do Your Own Research)

Conduct your own research before investing in a cryptocurrency, project, or financial product.

18. Whale

An individual or organization that owns or trades a large amount of a particular cryptocurrency. Large transactions by "whales" can impact the market, depending on the available liquidity.

19. Pump and Dump

A form of market manipulation where the price of an asset is artificially driven up, only for it to be sold off for a profit—often leaving other investors with losses.

20. Rekt

Crypto slang for suffering a significant financial loss.

21. Market Order

A trade order to buy or sell an asset immediately at the best available market price. The final execution price may differ from the last displayed price.

22. Limit Order

A trade order in which you set a maximum purchase price or a minimum selling price. The order is only executed if the price conditions are met and there is sufficient liquidity available.

23. Trading Pair

A combination of two assets that are traded against each other.
Example: BTC/USDT indicates that Bitcoin can be traded against USDT.

24. Spread

The difference between the best available buy price and the best available sell price for an asset.

25. Slippage

The difference between the expected execution price of a transaction and the actual price at which it is executed.

PART 2 — Wallets, Security, and Transactions

27. Wallet

A digital wallet used to manage cryptographic keys and to receive, send, or use cryptocurrency.
A wallet does not typically store your cryptocurrency in a literal sense; the associated assets are recorded on the blockchain.

28. Hot Wallet

A wallet where the keys are managed via a device or system connected to the internet. Hot wallets are convenient for frequent transactions but require robust security.

29. Cold Wallet

A wallet where private keys are kept offline. This can help reduce exposure to online attacks.

30. Custodial Wallet

A wallet in which a third party, such as a cryptocurrency exchange, manages the private keys on behalf of the user.

31. Non-Custodial Wallet

A wallet in which the user retains control over their own private keys and is responsible for securing them.

32. Private Key

A secret cryptographic key used to sign transactions or manage access to crypto assets.
Never share your private key with anyone.

33. Public Key

A cryptographic key associated with a private key. Depending on the system used, a receiving address can be derived from it.

34. Wallet Address

A blockchain address to which cryptocurrency can be sent. An address is not always the same as a public key.

35. Seed Phrase (recovery phrase)

A sequence of words that can be used to recover a wallet or its associated keys.
Anyone with access to your seed phrase may be able to control your crypto assets.

36. Transaction Hash (TxID)

The calculation method varies by blockchain. On Ethereum, "gas" is used to measure the computational effort required. Other networks use different mechanisms.

40. Gas Limit

The maximum amount of gas allocated for a transaction or the execution of a smart contract.
The gas limit is not the same as the final transaction fee.

41. Private Key Management

The secure creation, storage, use, and protection of cryptographic keys.
Proper key management is essential for both individual users and crypto-related businesses.

42. Multisig (Multisignature)

A security mechanism that requires multiple approvals before a transaction can be executed.
For example, a wallet can be configured so that two out of three authorized individuals must approve a transaction.

43. 2FA (Two-Factor Authentication)

Two-factor authentication adds an extra layer of security to an account—for instance, by requiring an authentication code in addition to a password.

44. Phishing

A form of fraud in which criminals impersonate a trusted organization or individual to obtain passwords, recovery phrases, or other sensitive information.

45. Dusting Attack

An attack in which very small amounts of cryptocurrency are sent to a large number of wallet addresses. The attacker may attempt to analyze transaction patterns to link these addresses together.
However, a small, unknown transaction on its own is not proof that a wallet has been hacked.

46. Rug Pull

A form of fraud in which the developers or administrators of a project exploit the trust of users—for example, by withdrawing liquidity or disappearing with the funds that have been invested.

47. Smart Contract Audit

Een technische beoordeling van de code van een smart contract om beveiligingsproblemen, programmeerfouten en mogelijke kwetsbaarheden op te sporen.
Een audit vermindert bepaalde risico's, maar garandeert niet dat een contract volledig veilig is.

DEEL 3 — Crypto-beurzen en financiële begrippen

Een handelsmechanisme dat smart contracts en vooraf bepaalde formules gebruikt om prijzen te berekenen en transacties tussen activa mogelijk te maken.

55. Slippage Tolerance

De maximale prijsafwijking die een gebruiker bij een swap accepteert voordat de transactie wordt afgewezen.
Een hoge tolerantie kan de kans vergroten dat een transactie wordt uitgevoerd, maar kan ook leiden tot een ongunstiger uitvoeringsprijs.

56. Arbitrage

Het benutten van prijsverschillen voor hetzelfde activum op verschillende markten of handelsplatformen.
Arbitrage brengt risico's en kosten met zich mee en garandeert geen winst.

57. OTC (Over-the-Counter)

Het rechtstreeks verhandelen van activa tussen partijen buiten het gebruikelijke openbare orderboek om.
OTC-diensten worden onder andere gebruikt voor grotere transacties.

58. P2P (Peer-to-Peer)

Een transactie of uitwisseling waarbij gebruikers rechtstreeks met elkaar handelen, eventueel met ondersteuning van een platform of escrowdienst.

An airdrop is not always free in an economic sense and may come with conditions, costs, or tax obligations.

185. Hard Cap

The maximum amount a project aims to raise during a specific funding round or token sale.

186. Soft Cap

The minimum amount a project aims to raise according to the terms of a funding round.

187. Fully Diluted Valuation (FDV)

An estimated valuation calculated by multiplying the price of a token by the maximum supply or another predetermined total supply metric.
FDV is an estimate and not a guarantee of future market value.

188. Token Migration

The process of transferring tokens to a new contract, network, or token structure.
Users should check the official instructions to avoid sending assets to an incorrect address. ### 189. Meme Coin
A cryptocurrency inspired, in whole or in part, by an internet meme, an online community, or a cultural phenomenon.
Its price can be highly dependent on attention, speculation, and market sentiment.

190. Burn Rate

A term that, depending on the context, refers either to the rate at which a company consumes financial resources or to the rate at which tokens are removed from circulation.

PART 10 — Common Abbreviations

PART 11 — Key concepts often confused by beginners

1. Coin vs. token

A "coin" is the native cryptocurrency of a blockchain. A "token" is typically issued on an existing blockchain.
Example:

• ETH is the native coin of Ethereum.
• USDT can exist as a token on Ethereum or TRON.

2. TRX vs. TRC-20

TRX is the native cryptocurrency of the TRON network.
TRC-20 is a token standard on TRON.
USDT on TRON is a TRC-20 token; it is not the same as TRX.

3. ERC-20 vs. TRC-20

ERC-20 is used for tokens on Ethereum. TRC-20 is used for tokens on TRON.
A token with the same name can exist on multiple networks. Therefore, choosing the correct network is essential when sending or receiving assets.

4. Wallet versus exchange account

A wallet manages or utilizes cryptographic keys that allow for the control of digital assets.
An exchange account provides access to the services and balance records of a trading platform.
In the case of a custodial exchange, the provider typically manages the keys to the wallets where client assets are held.

5. Staking versus lending

Staking involves committing assets to a blockchain consensus mechanism or a related protocol.
Lending involves providing assets to another party or through a protocol.
The risks, terms, and potential returns differ between the two.

6. Market Cap versus FDV

Market cap is generally calculated using the circulating supply.
FDV (Fully Diluted Valuation) uses a total supply metric, such as the maximum supply.
Both figures can be useful, but neither, on its own, indicates how much money has actually been invested in a project.

7. Stablecoin versus CBDC

A stablecoin is typically issued by a private entity or a protocol.
A CBDC (Central Bank Digital Currency) is a digital currency issued by a central bank.
While both can be used digitally, they differ in terms of their legal status, issuance, and risk structure.

8. Blockchain transaction versus payment

A blockchain transaction records an action on a blockchain.
A payment is an economic transfer of value, which can take place via blockchain technology, traditional banks, card networks, or other systems.

9. Decentralization versus security

A project can be decentralized while still containing vulnerabilities. Conversely, centralized services may employ robust security measures.
Decentralization and security are distinct characteristics.

10. APY versus guaranteed return

A high APY does not mean that the return is guaranteed.
Price fluctuations, fees, changing rewards, protocol issues, and other risks can affect the final outcome.

PART 12 — Safety tips for every crypto user

1. Always verify the receiving address. An incorrect transaction may be irreversible.
2. Check the blockchain network. Ensure you use a network supported by both the sending and receiving services.
3. Never share your seed phrase or private key. A legitimate support representative will never ask for this information.
4. Be cautious with unknown links and airdrops. Some are designed to drain wallets or steal sensitive information.
5. Check transaction fees. These vary by network and can fluctuate based on network congestion.
6. Research projects before investing. Examine factors such as the team, tokenomics, liquidity, contract addresses, and potential risks.
7. Do not mistake a high APY for a safe return. High yields often come with high risks.
8. Use robust account security. This includes using unique passwords, two-factor authentication (2FA), and secure devices.
9. Verify official contract addresses. Tokens with the same name can exist across different networks, and not all of them are legitimate.
10. Keep your recovery information safe. Losing your seed phrase could mean losing access to your assets permanently.
