1. Blockchain
A decentralized digital ledger that tracks transactions via a network of computers is called a blockchain. In contrast to conventional databases that are managed by a single entity, blockchains disperse data among thousands of nodes, which makes them extremely safe and impenetrable. Because of this technology, cryptos can function without centralized authorities like banks.
Why it matters: Blockchain's transparency and security benefit financial institutions, supply chains, and identity verification. Even governments and large enterprises are exploring blockchain technologies nowadays.
Did you know? According to Statista, the Bitcoin blockchain contains a continuously growing and tamper-evident list of all Bitcoin transactions and records since its initial release in January 2009.
2. Decentralization
Decentralization disperses authority throughout a network rather than depending on a central authority. In the cryptocurrency world, no single institution has the authority to make decisions or regulate transactions. Decentralized networks can reach consensus by using algorithms and community governance.
Why it matters: True decentralization protects against censorship and single points of failure. However, achieving full decentralization remains a challenge for many projects.
3. Smart Contracts
On blockchains, smart contracts are self-executing programs. They eliminate the need for middlemen in various arrangements, including financial transactions and legal proceedings, by acting automatically when specific conditions are met. Ethereum initially made smart contracts popular, but many other blockchains now support them.
Why it matters: Smart contracts enable complex applications like DeFi protocols and NFT marketplaces to operate trustlessly. Their code-based nature reduces human error and manipulation.
Did you know? As demonstrated by the $60 million DAO attack in 2016 that led to Ethereum's controversial hard fork, a single bug in a smart contract can result in enormous damages.
4. Gas Fees
Gas fees are the computational costs of processing transactions or executing smart contracts on blockchains like Ethereum. To reimburse validators for network resources, users pay these fees in the local cryptocurrency, such as ETH.
Why it matters: During periods of high demand, gas fees can skyrocket, making small transactions economically unviable. This incident remains one of blockchain's biggest scalability challenges.
Did you know? The average Ethereum gas fee peaked at over 500 gwei during NFT booms in 2021.
5. HODL
Despite volatility, HODL (originally a misspelling of "hold") has become crypto culture's mantra for long-term investing. The term emerged from a 2013 Bitcoin forum post where a user vowed to hold through a market crash.
Why it matters: The HODL philosophy opposes emotional trading and has proven effective for patient investors during crypto's boom-bust cycles.
6. Whale
The blockchain terminology "whale" describes individuals or entities holding large amounts of cryptocurrency, significantly influencing market prices. These big players can cause substantial price movements when they buy or sell their holdings. Whales are often institutional investors, early adopters, or crypto foundations with massive token reserves.
Why it matters: Whale activity can serve as both an opportunity and a warning sign for retail investors. Large transfers to exchanges often precede price drops, while accumulation can signal upcoming rallies.
7. FUD & FOMO
The crypto terminology "fear, uncertainty, and doubt" (FUD) describes the dissemination of unfavorable information that causes unjustified panic in markets. On the other hand, FOMO, which stands for "fear of missing out," refers to the desire to purchase assets just because their prices are growing quickly. These are psychological factors that commonly cause irrational market activity.
Why it matters: Investors can make more logical choices when aware of these emotional triggers. Buying at peaks is due to FOMO, and selling at bottoms is due to FUD, which causes many traders to lose money.
8. Staking
Staking entails locking up cryptocurrency to participate in proof-of-stake blockchain transaction validation. In exchange, the stakeholder receives compensation in the form of interest payments. Major crypto networks, such as Ethereum, Cardano, and Solana, use staking techniques. To guide you where to stake, check out our list of the best staking crypto platforms.
Why it matters: The crypto terminology staking provides a way to earn passive income while supporting blockchain security. However, it typically requires locking funds for set periods, reducing liquidity.
Did you know? Ethereum's switch to Proof-of-Stake addressed significant environmental concerns about blockchain technology by reducing its energy consumption by 99.95%.
9. DeFi (Decentralized Finance)
DeFi describes blockchain-based financial apps that function without conventional middlemen like banks. These include loan platforms, decentralized exchanges, and yield farming methods that use smart contracts.
Why it matters: The crypto terminology DeFi offers global access to financial services with essentially higher yields than traditional finance, though with greater risks. The sector has grown from 1 billion to over 80 billion in TVL since 2020.
10. Impermanent Loss
Impermanent loss happens when investors provide liquidity to automated market maker (AMM) pools, and the value of their deposited assets changes compared to simply holding those assets. Investors who withdraw liquidity during unfavorable price movements make this "loss" permanent.
Why it matters: Liquidity providers must weigh potential fee earnings against possible impermanent loss, which can sometimes exceed trading fee rewards.
11. MEV (Miner Extractable Value)
MEV, or Miner Extractable Value, refers to the extra profits that blockchain validators can gain by rearranging the order of transactions in their blocks. This can include prioritizing certain transactions or even omitting others, as a common example.
Why it matters: MEV creates inefficiencies in DeFi markets and can lead to worse prices for regular users. Solutions like Flashbots aim to democratize MEV opportunities.
12. Airdrop
Airdrops are free distributions of cryptocurrency tokens, typically used as marketing tools to bootstrap communities or reward early adopters. Some require simple tasks, while others reward past protocol usage.
Why it matters: Strategic airdrop participation can be highly profitable, with some recipients earning thousands or even millions from free token allocations.
Did you know? On September 16, 2020, Uniswap (UNI) carried out the largest crypto airdrop in history, delivering $6.43 billion in tokens at an all-time high price of $42.88.
13. Rug Pull
A rug pull occurs when cryptocurrency developers abandon a project and leech off investors' funds, often by draining liquidity pools or selling their pre-mined tokens. These scams frequently target inexperienced investors in new projects.
Why it matters: Rug pulls account for most crypto scams, making due diligence essential before investing in new tokens.
Did you know? The Squid Game token rug pull in 2021 saw developers make off with $3.38 million, highlighting the risks of hype-driven investments.
14. OTC (Over-the-Counter) Trading
OTC trading in crypto refers to large-volume transactions that occur directly between buyers and sellers, bypassing public exchanges. This method is ideal for institutional investors or high-net-worth individuals seeking to purchase significant amounts of cryptocurrency without triggering slippage or sharp price movements.
Why it matters: OTC desks provide liquidity for large investors while minimizing market impact.
15. LRTs (Liquid Restaking Tokens)
Liquid Restaking Tokens, or LRTs for short, are tokenized representations of restaked assets that allow users to preserve liquidity while earning several tiers of staking benefits. EigenLayer's restocking protocol gave rise to these innovative tokens, which allowed ETH stakers to take part in safeguarding networks other than Ethereum.
Why it matters: LRTs solve the capital efficiency problem in staking by letting users earn rewards across multiple protocols simultaneously while keeping assets liquid for trading or DeFi use.
Did you know? According to Inception, the top 7 LRTs represent 60% of all EigenLayer restaked assets.
