Cryptocurrency Alerting

Crypto Glossary

Beginner-friendly explanations for common terms used within the crypto ecosystem.

51% Attack

A specific method of attacking a blockchain, where a single group of miners control more than 50% of the network. This allows a centralized party to control the "truth", effectively destroying its integrity.

Accredited Investor

Someone who has a net worth greater than $1,000,000 and meets certain additional income requirements. Qualifying individuals may file with the SEC to obtain this status. In the United States, only accredited investors may invest in hedge funds, venture capital funds, and other "advanced" forms of investing.


An event in which a blockchain project gives away ​tokens or​ ​coins for free. A simple condition may need to be met, such as having a certain existing balance in your wallet or registering before a deadline. Teams may elect to do this to raise awareness of a project, or ensure that a cryptocurrency is not consolidated among too few people.

Our platform provides free airdrop monitoring of any Ethereum wallet.

Air Gapped Device

A device that has never been (and will never be) connected to an unsecure network, such as the internet. This is a strategy to store cryptocurrency as safely as possible.

ASIC (Application Specific Integrated Circuit)

A computer that is specifically designed to mine cryptocurrency. The rise of ASICs has lead to more miner centralization since they make it harder to be profitable mining on a regular CPU or GPU.

Atomic Swap

The exchange of one cryptocurrency for another without the need for a trusted third party, such as an exchange. Atomic Swaps happens directly on the blockchain.

ATH (All Time High)

The highest price an asset has ever been sold for.

Algorithmic Trading (Algo Trading)

A strategy of using software to strategically buy and sell assets. This software is commonly referred to as a "trading bot" or an "algorithmic trading bot".

To "ape in" to an asset or a trade is to buy a position in it. This sometimes means the decision was made recklessly, or a large amount was invested, but the usage varies.


A price difference between the same asset across different markets. When this occurs, traders can buy on the exchange with the lower price and sell on the higher (turning a profit). This often happens due to low liquidity in an inefficient market. Over time, as arbitrage traders capitalize on the opportunity, the price gap will becomes smaller and eventually converge back to an unprofitable level.

Our platform can help detect arbitrage opportunities by using our "Any Exchange" price alert or percentage price alert.


Using historical data to test a predictive model or trading strategy in order to determine its effectiveness.


Someone still holding an altcoin after a market crash.


Baking is the process that Tezos uses to append new blocks of transactions to its blockchain. It is a kind of delegated proof of stake. Bakers receive rewards for each block baked, similar to how Bitcoin miners receive rewards for discovering new blocks. A baker is more likely to bake a block if they have a larger number of rolls (groups of 10,000 XTZ). Accounts must be registered as a delegate in order to partake in the baking process, and can bake on behalf of other accounts who do not meet the 10,000 XTZ requirement.

Buy The Dip (BTFD)

A common expression and piece of advice. It is the suggestion that someone should buy an asset whenever it drops in price, since its inevitably going to go back up in price.

Black Swan Event

A catastrophic event that is very unlikely to occur (but given enough time, will almost certainly occur).


The thing being mined by miners. It's where transactions are stored. Once written, it cannot be altered or removed. It can be thought of like a page in a public ledger.

Block Lattice

A specific type of DAG (Directed Acyclic Graph) first introduced by the Nano cryptocurrency. Each account has one blockchain which is controlled by the account's private key, and each blockchain is replicated to all peers in the network. This arrangement is called a block lattice.

Block Size

Byzantine Fault Tolerance

The characteristic of a system that is able to tolerate the issues brought up by the Byzantine Generals’ Problem.

Byzantine Generals’ Problem

A thought experiment that is intended to illustrate the difficulty of reaching consensus in a distributed system. In the problem, a group of generals who each command a portion of the army, surround a city. These generals must develop a plan to either attack or to retreat. Every general must reach a collective decision (if a unified decision is not reached, and some generals decide to attack, while others retreat, then the uncoordinated attack or retreat, the army will fail). Generals must coordinate via messengers (whom may lie) and generals themselves may be traitorous.

Candlestick Chart

A common way to graph the price of a financial asset over time. It differs from a basic line chart in that it contains more information. Each period, or "candle", contains the open, high, low, and closing price. A green candle typically means the price has gone up, and a red one means down.

Capital Gain

Profit that results from the sale of an asset.


A large, final wave of panic selling where a market experiences a "bottom" for a given cycle.

Cold Storage

Keeping a cryptocurrency stored offline, as a security precaution to prevent theft.


A transaction is considered to be confirmed once it has been written to the blockchain. If a transaction has multiple confirmations, it means that additional blocks have been mined after the block that contains the transaction in question. The higher the confirmation number, the more certainty that a coin has not been double spent.

Our Wallet Watch service offers notifications when transactions have been confirmed on your wallet.

Consensus Mechanism

A consensus mechanism is the method that a blockchain uses to decide on the individual contributions of all its participants. Common examples are Proof of Work and Proof of Stake.


A price consolidation occurs when the price of an asset remains within a tight range for a period of time. This is usually considered to be a "pause" between the next larger price move.


A correction in a market is a drop in price after a significant gain, suggesting that the market is "correcting" back toward the mean.

DPoS (Delegated Proof of Stake)

Invented by Daniel Larimer, it is an alternative consensus mechanism to Proof of Work. A cryptocurrency that uses DPoS votes for a "witnesses" to secure their computer network. Coin holders vote for "delegates", who are then responsible for validating transactions and maintaining the blockchain. It's used as a consensus mechanism in various cryptocurrencies such as BitShares, Lisk, EOS, Tezos, Ark, Nano and Cardano.

Death Cross

A technical analysis indicator, where a short-term moving average crosses below a long-term moving average. This is considered to be a bearish signal.

Fundamental Analysis (FA)

A methodology of analyzing a potential intrinsic value of an asset based on both qualitative and quantitative factors such as economic metrics, competition and their product.

Funding Rates

Funding Rates are periodic payments made by those holding a position of a perpetual futures contract. When the funding rate is positive, the price of the perpetual contract is higher than the market price. Thus, traders who are long pay to those with short positions. Conversely, a negative funding rate means that short positions pay to those who are long. Crypto funding rates aim to prevent divergence in the price between the futures contract and the current market (or index) price. The rate is expressed as a percentage. Positive funding rates imply that more traders are currently long vs short, and vice versa. While this can be used to measure market sentiment, it will not necessarily predict price movements.


An asset where each unit is essentially identical and interchangeable with one another.

Futures Contract

A derivative product representing a legal agreement to buy or sell an asset at a predetermined price at a specified time in the future.


The internal pricing for running a transaction or contract on Ethereum.

Impermanent Loss

When you provide liquidity to a market (likely a DEX) and the price of the token differs from when you first deposited them into the liquidity pool. Trading fees can help counteract this. Impermanent Loss happens when it would have been more profitable to just hold on to a given asset rather than provide liquidity in a pool.

MEV (Miner Extractable Value

MEV represents value that can be acquired from a block by re-ordering including, and excluding transactions. While transactions with the highest fees are typically always included in the next block, miners are not required to sort the transactions by highest paid fees. This allows them to reorder transactions to extract additional profits from users.


To increase drastically in value.

Moving Average

A technical analysis indicator which takes the average of a specific number of previous data points in order to calculate its present value.

Prisoner's Dilemma

A common situation in game theory -- when individual players each acting in their best interest produce an undesired result that makes the whole group worse off.

Private Key

A a string of letters and numbers that serves as a cryptographic key allowing a transaction to be sent over the blockchain. This is essentially your password for a wallet address, and should be held as securely as possible.

PoI (Proof of Importance)

A blockchain consensus algorithm first introduced by NEM. Proof of Importance is the mechanism that is used to determine which nodes are eligible to add a block to the blockchain (this process is known as "harvesting" in NEM). It is different than Proof of Stake in that it factors one’s overall support of the network into account, not just the current moment in time. Vesting, transaction partners, number and size of transactions are all factors.


A group of financial assets in someones possession. Each item in this group is known as a position.


An single element in a portfolio. The amount of a specific asset that is held.

PoS (Proof of Stake)

The ability to mine cryptocurrency by simply holding coins in a wallet that is connected to the network. The more coins in the wallet, the more mining power.

PoW (Proof of Work)

A piece of data that is computationally difficult to produce but easy for others to verify. It is the primary thing that miners do to discover new blocks and contribute to the integrity of the network.

Public Key

The address used to send someone an amount of cryptocurrency. If a private key is your password, a public key is your username.

Quadratic Voting

A specific voting process, and a proposed method of governing a blockchain. Voters are able to express how strongly they feel about an issue by purchasing more votes for a specific outcome. While voters can vote as many times as they want, the cost of each vote increases exponentially.

Pump & Dump

A coordinated manipulation of the price of an asset. A whale or group of people all start buying a cryptocurrency causing the price to drastically increase very rapidly. This often causes wild speculation and others start buying it out of excitement. The original actors immediately sell everything they originally bought causing the price to come tumbling back down.

Recovery Phrase

Also known as a mnemonic seed, it is a list of words which store all the information needed to recover a private key.

Resistance Level

It is a price that a given asset typically has trouble reaching above. If it does reach above that level, it will likely climb even higher now that this level has been broken.


Getting "wrecked". Losing a lot of money on an investment.

Ring Signature

A technology used by Monero in order to obfuscate the input of a transaction. A message signed with a ring signature appears to be endorsed by any person within a certain group of people. It is computationally infeasible to determine which member of the group actually produced the signature.

ROI (Return on Investment)

The percentage gain/loss on an investment.

Ross Ulbricht

The creator of the Silk Road, currently serving a life sentence in jail. Known under the pseudonym "Dread Pirate Roberts".

RSI (Relative Strength Index)

A technical analysis indicator used to identify overbought or oversold conditions when trading an asset.

Rug Pull

A rug pull is usually when the creators of a project take all the money and run. Its when a project turns out to just be a scam.

Safe Haven Asset

A financial asset that is expected to perform well (or at least retain its value) during an economic downturn. Gold is a common example, and many people think Bitcoin has the potential to display similar properties.

satoshi (sats)

The smallest atomic unit that a Bitcoin can be divided into. 1 satoshi = 0.00000001 BTC

Satoshi Nakamoto

The name of the anonymous creator (or creators) of Bitcoin and the author of the original Bitcoin whitepaper.


Also called a shitcoin, this refers to a token that provides little or no value, and is simply propped up on hype and false promises.

Schelling Point

A concept or solution that people tend to choose by default in the absence of communication. The concept was introduced by Thomas Schelling in the book "The Strategy of Conflict". Has popular use in game theory.


A hash function used by certain cryptocurrencies (notably Litecoin) as an alternative to SHA-256. It is more memory intensive, which means it is not well suited for ASIC hardware. This ensures that CPU and GPU remain viable methods to mine the coin.

SEC (Securities and Exchange Commission)

A US federal government agency responsible for protecting investors by regulating securities markets. The mission statement of the SEC is to "promote a market environment that is worthy of the public's trust".

STO (Security Token Offering)

Similar to an ICO, but the tokens issued offer more rights and may be backed by assets, profits, or revenue generated by companies. The idea is to give these tokens tangible value from day one, and reduce the component of hype and speculation.

Segwit (Segregated Witness)

An upgrade to the Bitcoin protocol where signature data is removed from transactions, allowing more transactions to fit in a single block, increasing the speed of the network.

Sell Wall

A large sell order set at a specific price, likely to prevent higher sell orders from executing. This may be the result of whales attempting to keep the price of an asset low.


Someone trying to spread hype about something by endorsing the product in public. Typically has negative associations.


A method of encryption. Stands for Secure Hash Algorithm. Is involved in the mining process for Bitcoin and other cryptocurrencies.


A method of scaling a blockchain (increasing how many transactions can be processed per second) by splitting up which miners are working on what at a given time.

Shielded Address

A kind of address used by ZCash that is highly private. They are not visible in the blockchain and offer strong privacy against transaction graph analysis. The value transferred is private if both the sender and receiver are shielded. Shielded addresses are not supported in every ZCash wallet.


A method of betting on an asset decreasing in value. When someone shorts an asset, the investor borrows that asset and immediately sell it, hoping to buy it back when it is cheaper.

Short Squeeze

A rapid increase in the price of an asset due to a large number of short positions being liquidated at the same time.


The ability to transfer assets from one blockchain to a separate blockchain and then be moved back if needed. It's a way for multiple cryptocurrencies to interact with one another.


Information that allows someone to prove that they have a private key, without having to reveal the actual private key.

Silk Road

An online black market, popularized as a platform for selling illegal drugs. It was only accessible via TOR, and only accepted Bitcoin as payment, which were tumbled in order to increase anonymity. Created by Ross Ulbricht.

SIM Jacking

Also known as a SIM swap scam or SIM splitting, this is a method of hijacking someone else's phone number in order to gain access to other accounts tied to that person. The hacker does this by gaining basic information about the victim and then contacting their phone provider pretending to be them. It is advised to use an app such as Google Authenticator instead of a phone number for two-factor authentication (2FA).


Slippage occurs when there isn't enough liquidity in a given market to buy or sell an asset without affecting the market price. It's the difference between the expected price and the actual price when the trade executes. It's often expressed as a percentage.

Smart Contract

A programmable way of executing logic on the blockchain. In addition to exchanging money, smart contracts allow arbitrary assets to be exchanged while avoiding a middleman.


To "snipe" something is to get a good deal on it. To pay less than you think it's worth.

Soft Cap

The minimum amount of money raised in an ICO in order to consider it a success.

Soft Fork

A change in the protocol that is backward-compatible, and generally does not require users to upgrade their wallets or take any other action. See: Hard Fork.


A high level programming language for writing smart contracts on the Ethereum network.

Spot Price

The current market price for a given asset.

Stacking Sats

Acquiring Bitcoin. Sats refers to Satoshis, the smallest atomic unit of BTC.

Stock to Flow Modal (S2F)

A theoretical model of Bitcoin's past and future price, primarily influenced by the amount of Bitcoin being mined at any given time. This means that the halving is the primary event that influences the price of Bitcoin, according to this model.

Stable Coin

A cryptocurrency that is pegged to a specific value (usually a fiat currency) and is intended not to fluctuate in price.


The process of holding funds in a cryptocurrency wallet to support the network of the blockchain that is tied to those funds. This is an alternative to traditional mining.

Stealth Address

A way of sending cryptocurrency by giving additional privacy to the recipient. By using a stealth address, you ask payers to generate a unique address in such a way that you can deduce the corresponding private key. So although a single "stealth address" can be visible in public, the blockchain sees all incoming payments as going to separate addresses.

Stop Limit

An order to buy or sell an asset that combines the features of a stop order and a limit order. Once a stop price is reached, a limit order is placed.

Stop Loss (Stop Order)

An order designed to limit an investor's loss on a position. A trade that gets executed once a price reaches a certain level.

Store of Value

An asset that can be reliably saved, retrieved, exchanged and predictably useful. Anything that retains these qualities as time passes is a good store of value.

Swing Trader

A strategy of trading assets over a period of a few days to several weeks, in order to turn a profit.

Swing Trader

A strategy of trading assets over a period of a few days to several weeks, in order to turn a profit.


A type of DAG (directed acyclic graph) used by IOTA. It's a network consisting of nodes that issue and validate transactions. A qualifying node must choose two other transactions to approve, ensure approved transactions are not conflicting, and solve a cryptographic puzzle. A "coordinator" is currently used as a centralized consensus mechanism to prevent attacks on the network, and is scheduled to be shut down once the network is stable enough.

Technical Analysis (TA)

A methodology of valuing the price of an asset based on studying market data, such as patterns in price and volume.


An alternate blockchain meant for testing purposes. Coins on this chain have no value. See: Mainnet.

Ticker Symbol

The abbreviation used to identify an asset on an exchange. They are typically 3 or 4 characters, and capitalized. For example, the ticker symbol for Bitcoin is BTC.


A cryptocurrency that relies on another cryptocurrency (such as Ethereum) in order to operate. A token does not have a blockchain of its own.

TGE (Token Generation Event)

Another way of describing an ICO (Initial Coin Offering).

Trading Bot

A computer program that automatically buys and sells assets based on the rules that it was programmed with. It can incorporate any number of strategies behind its logic, such as arbitrage, technical analysis or even social media sentiment analysis.

Trading Indicator

Trading indicators are any metrics that are used to help inform someone of a potential trade.

Trading Signal

Trading signals are automated notifications that suggest to a trader than it is a good time to buy or sell an asset.

Total Supply

The amount of coins in existence. This number subtracts any coins that have been burned.

TOR (The Onion Router)

Open-source software designed to protect a user from Internet surveillance by routing traffic across a randomized set of proxy servers.

Trailing Stop Loss

A specific way of using a stop loss order. As the price of an asset rises, the stop price rises as well. But if the price falls, the stop loss price doesn't change. This is a way to limit losses while locking in gains.

Transaction Fee

An expense that must be paid to miners in order for a cryptocurrency to be sent to a different wallet. This fee can vary based on how congested the network is, among other things.

Transactions Per Second

The number of transactions that a given blockchain can handle/process each second. This is the primary metric used when thinking about scaling blockchains.

Trend Line

A line that can be drawn (either horizontal or diagonal) in which the value of a given asset or indicator can frequently bump into but not cross. If a trend line is crossed, a larger price movement often follows.


A system that minimizes the amount of trust required from any single person or entity in a system by distributing it among many agents within it.

Turing Complete

Turing completeness is a quality that a programming language possesses if it can be used to emulate a Turing Machine.

Turing Machine

A Turing machine is a system that can simulate any computer algorithm, regardless of its complexity.

Txid (Transaction Identifier)

A (mostly) unique identifier for a given transaction.

Unconfirmed Transaction

A transaction that has not yet been included on a block, so it is still in a pending state.

Unspent Transaction Output (UTXO)

UTXOs are a fundamental concept behind the way cryptocurrency is transferred on many blockchains, including Bitcoin. The total UTXOs tied to a given wallet address represents the amount of funds available in that wallet. Every transaction consumes elements from this set and creates new ones. When funds are sent to a wallet address, the remaining balance in that wallet is sent back to itself as an UTXO.

User Activated Soft Fork (UASF)

A change in the blockchain protocol enacted by a majority of full nodes (as opposed to miners).

Vanity Address

An address that you choose yourself, or at least partly. Different blockchains have different capabilities around this.

Vitalik Buterin

A co-founder of Ethereum and a prominent voice in the cryptocurrency community.


A measure of how rapidly and unexpectedly an asset has historically changed in price.


The number of coins or tokens traded on an exchange in a given period of time.

Volume Spike

When trading volume dramatically increases in a short period of time. This often occurs in tandem with large price movements. A volume spike is often considered to add "conviction" to a price movement, and confirms a breakout from a trend line or pattern.

WAGMI (We All Gonna Make it)

"Making It" means becoming wealthy. This is sometimes just abbreviated to GMI.


A wallet allows someone to store the private key for a given blockchain address. They come in many shapes and sizes, such as hardware, paper and brain wallets.

Our Wallet Watch service offers free wallet monitoring for the Bitcoin and Ethereum blockchains.

Weak Hands

People who panic sell when the price of an asset begins to plummet. Sometimes called "paper hands".

Web 3

Web 3 refers to new paradigm of building websites. Rather than each website redundantly storing user data in their own database (such as having an account on Twitter or Youtube), a website can simply connect to a crypto wallet in order to "log in". That same crypto wallet will allow a user to log into any web 3 compatible site. A separate account for each site is not necessary. Each website will not need to store user data, and if the website ever gets hacked, there will be no sensitive information to leak. This allows users to truly own their data and take it with them when they stop using a website.


A very wealthy person who can single-handedly manipulate the price of an asset.


An informational document that outlines a proposed solution or methodology for a given organization. This has become the go-to way for ICOs to market their token.


In a candlestick chart, a wick is the line extending from the top or the bottom of a candle. It represents the high or low price relative to the opening or closing price. In short, it shows the price extremes within a candle.

Wrapped Bitcoin

Wrapped Bitcoin (WBTC) is an ERC-20 token backed by Bitcoin. Allows BTC to be used in the DeFi & Ethereum ecosystem.

Wrapped Ether

Wrapped Ether (WETH) is an ERC-20 token backed by Ethereum. Since Ethereum existed before the ERC-20 standard, it is not natively compatible as a token, and a smart contract must be used to achieve this. Wrapped Ether allows ETH to be directly exchanged for an ERC-20 token without a trusted third party.


An informal currency code for Bitcoin. You can sometimes use this on your stock ticker app to track the price of BTC.

Yield Farming

Yield farming is a process of earning interest and generating a return on capital within the DeFi & Ethereum ecosystem. This refers to a combination of numerous techniques involving incentive schemes, liquidity pools and leverages borrowing. Popular platforms where yield farming takes place include Compound, Aave, 0x, Balancer, Uniswap and Synthetix.

Zero Knowledge Proof

A method that lets someone prove possession of certain information (such as a secret key), without revealing that information, and without any interaction between the prover and verifier.

Zero-Sum Game

A system where one persons gain must mean that someone else has incurred a loss. In a zero-sum game, there is no way for everyone to benefit mutually at the same time.


An implementation of a Zero Knowledge Proof used by ZCash among other cryptocurrencies.
