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.
Consolidation
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.

An asset who’s price is designed to remain the same as another asset, such as a stablecoin.
Perpetual Swap
A derivative product similar to a futures contract, but has no expiration date. BitMEX has popularized this kind of crypto derivative.
Pre-mine
Pre-mining is the creation of a certain number of tokens before the cryptocurrency is available to the public.
Pre-sale
A sale event that runs prior to the proper crowdsale in an ICO. There is usually a low cap to the funds raised, and they are often sold in bulk or at a discount.
Price Rally
An increase in the price of an asset over a sustained length of time.
Priced-In
When discussing a certain piece of information and how it relates to the price of an asset, it is said to be “priced in” when the current market price has already factored in this information.
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.
Portfolio
A group of financial assets in someones possession. Each item in this group is known as a position.
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.
Rekt
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.
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.
Scamcoin
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.
Scrypt
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.
Shill
Someone trying to spread hype about something by endorsing the product in public. Typically has negative associations.
SHA-256
A method of encryption. Stands for Secure Hash Algorithm. Is involved in the mining process for Bitcoin and other cryptocurrencies.
Sharding
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.
Short
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.
Sidechain
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.
Signature
Information that allows someone to prove that they have a private key, without having to reveal the actual private key.
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.
Solidity
A high level programming language for writing smart contracts on the Ethereum network.
Spot Price
The current market price for a given asset.
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.
Staking
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.
Tangle
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.
Testnet
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.
Token
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.
Trustless
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.
Volatility
A measure of how rapidly and unexpectedly an asset has historically changed in price.
Volume
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.
Wallet
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.
Whale
A very wealthy person who can single-handedly manipulate the price of an asset.
Wick
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.
XBT
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.
Zk-SNARKs
An implementation of a Zero Knowledge Proof used by ZCash among other cryptocurrencies.
