Crypto Market Terms Glossary

Liquidity

Liquidity is how easily a coin can be bought or sold without moving its price much. A liquid market has enough buy and sell orders sitting close to the current price that a normal-sized trade barely disturbs it. A thin market doesn't — even a modest order can shove the price around.

Liquidity and market cap aren't the same thing. A coin can carry a large market cap on paper while trading in a thin, illiquid market if most of its supply sits untraded in wallets rather than sitting on exchange order books.

Slippage

Slippage is the gap between the price you expected when you placed a trade and the price you actually got when it filled. It shows up most on illiquid coins or unusually large orders, where there aren't enough matching orders at your target price to fill the whole trade.

Most exchanges let you set a slippage tolerance — a maximum acceptable gap — and cancel the trade automatically if the market moves past it before your order fills.

ATH and ATL

ATH is a coin's all-time high price; ATL is its all-time low. Both are simple historical markers, tracked from whichever point exchange data for that coin begins. Neither says anything about where a price is headed next — they're a record of the past, not a prediction.

TVL (Total Value Locked)

TVL is the dollar value of assets currently deposited in a protocol — a lending market, a DEX's liquidity pools, a staking contract. It's a rough proxy for how much a protocol is being used, since it reflects how much capital people are trusting it with right now.

A high TVL isn't automatically a safety signal. It measures scale, not audit quality or how secure the underlying code is — a protocol can hold enormous TVL and still carry real smart-contract risk.

Tokenomics

Tokenomics is shorthand for a token's economic design: how many coins exist, how new ones get created or removed, who holds them, and what they're used for. It's the set of rules that shapes supply and demand over the long run — vesting schedules, emission rates, staking rewards, and burn mechanisms all fall under this umbrella.

Reading a project's tokenomics is usually the fastest way to understand why its supply — and therefore the gap between market cap and FDV — behaves the way it does.

Gas Fees

Gas is the fee paid to a blockchain network to process a transaction — a swap, a transfer, a smart-contract interaction. It goes to whoever validates the block your transaction lands in, not to any exchange.

Gas fees rise and fall with network demand: more people trying to transact at once pushes the fee needed to get included in the next block higher, then it eases back down once demand drops. Different blockchains have very different typical gas costs, which is why the same type of trade can cost cents on one network and dollars on another.

CEX vs DEX

A CEX (centralized exchange) is a company — Binance, Coinbase, and similar platforms — that holds custody of your funds and matches your trades internally. You trust the company to keep your assets safe and process withdrawals correctly.

A DEX (decentralized exchange) is software running on a blockchain that lets you trade directly from your own wallet. No company holds your funds at any point; trades settle through smart contracts instead. The trade-off is that you're responsible for your own wallet security, with no company to call if something goes wrong.

Stablecoin

A stablecoin is a token designed to hold a steady price, almost always pegged to a fiat currency like the US dollar. They exist to give traders a way to hold value or move between positions inside crypto markets without cashing out to a bank.

Not all stablecoins keep their peg the same way — some hold real dollar reserves, others use crypto collateral or algorithmic mechanisms. That difference matters, since it's exactly what determines how a stablecoin behaves under stress.

Staking

Staking means locking up a coin to help secure its network — usually a proof-of-stake blockchain — in exchange for rewards paid in that same coin. It's the proof-of-stake equivalent of what mining does for proof-of-work chains: committing a resource to keep the network running, and getting paid for it.

Staked coins are typically locked for a period and can't be freely traded until unstaked, so staking yield needs to be weighed against giving up that flexibility.

Whale

A whale is a wallet or entity holding a large enough position in a coin that its trades can move the market on their own. There's no fixed threshold — what counts as a whale depends entirely on how liquid that specific coin is.

Whale activity gets watched closely because a single large sell can trigger the kind of price move that smaller traders then react to, amplifying the initial move.

DYOR and HODL

DYOR — "do your own research" — is a standard reminder across crypto communities that no post, chart, or tool (including this one) should substitute for checking things yourself before acting on them.

HODL started as a typo for "hold" and stuck as shorthand for holding a position through volatility rather than trading in and out of it. Both are community shorthand more than technical terms, but they show up often enough to be worth knowing.
