An exit scam is a fraudulent practice in which the founders of a cryptocurrency project or exchange suddenly disappear with investors' funds. These scams typically involve projects promising high returns but lacking any real product.
F
Fiat currency
A fiat currency is a government-issued currency, such as the dollar, euro, or koruna, controlled by a central bank. It is not backed by any physical asset, and its value depends on trust in the state and its economy. Governments regulate the supply of fiat money and use it for economic policy management, which can lead to inflation. Unlike cryptocurrencies, which are decentralized and governed by algorithms, fiat currencies are subject to central institutional decisions.
Fireblocks
Fireblocks is a security infrastructure for managing digital assets, used by banks, exchanges, and financial institutions to protect cryptocurrencies. Probinex has integrated Fireblocks into its ecosystem to ensure maximum security for user funds.
FOMO (Fear of Missing Out)

Fork (Blockchain Split)
A fork is a change in blockchain network rules that leads to the creation of a new version of the blockchain. A soft fork is a backward-compatible update, whereas a hard fork creates an entirely new blockchain (e.g., Bitcoin Cash, which originated from Bitcoin).
Front Fee
An entry fee charged during the allocation and reallocation of funds. This fee covers the costs associated with trading activities and ensures efficient capital redistribution.
FUD (Fear, Uncertainty, Doubt)
FUD refers to the spread of negative news or misinformation aimed at causing panic and a decline in cryptocurrency prices. It can be triggered by regulatory changes, negative media coverage, or market manipulation.
G
Gas (Transaction Fee on Blockchain)
Gas is a unit that measures the computational power required to execute a transaction or smart contract on a blockchain, such as Ethereum. The gas fee depends on network congestion and the complexity of the operation.
Governance (Decentralized Project Management)
Governance in cryptocurrencies refers to the decision-making process regarding the future of blockchain protocols and projects. It can be centralized (controlled by a single entity) or decentralized (where governance token holders make decisions). Projects like DAOs (Decentralized Autonomous Organizations) allow users to vote on changes within the ecosystem.
Grant Thornton
Grant Thornton is an international advisory firm specializing in auditing, taxation, and regulatory consulting. In the cryptocurrency and blockchain space, it assists companies with regulatory compliance, digital asset audits, and the implementation of compliance strategies.
Greater Fool Theory
The Greater Fool Theory describes an investment strategy where people buy overvalued assets, believing they can sell them to an even “greater fool” at a higher price. This concept is common in cryptocurrency markets, especially during speculative bubbles.
H
Hard Peg (Fixed Peg to Another Currency or Asset)
A hard peg is a mechanism where the value of a currency or asset is strictly tied to the value of another asset, usually a fiat currency or commodity. This means its price remains fixed or moves only within a predefined range. In cryptocurrencies, hard pegs are commonly used in stablecoins, such as USDT (Tether) or USDC, which are pegged to the US dollar at a 1:1 ratio.
High-Frequency Trading (HFT)
HFT is a trading strategy that uses algorithms to execute a large number of trades in a very short time. This approach is popular in both traditional markets and cryptocurrencies.

Probinex prioritizes user security and employs advanced technologies such as Fireblocks, which combine the convenience of a hot wallet with the protection of cold storage.
I
ICO (Initial Coin Offering)
An ICO is a fundraising method for new crypto projects, where investors purchase newly issued tokens before they are listed on an exchange. This model was especially popular in 2017–2018. A total of 55% of the PBX ICO was offered to early investors in 2021. 550,000,000 PBX tokens found their new owners by November 2021, a month earlier than the planned end of the presale. The token sale raised $17,550,000 USD.
Immutable Ledger
Blockchain functions as an immutable ledger, where all transactions are permanently recorded and cannot be altered retroactively. This characteristic ensures transparency and data security.
Inflation
Inflation in crypto refers to the gradual increase in the number of tokens or coins in circulation, which can reduce their value. For example, Bitcoin follows a deflationary model, as its supply is capped at 21 million BTC, whereas Ethereum’s inflation was reduced after transitioning to the Proof-of-Stake (PoS) model.
J
Jevons Paradox
Jevons' Paradox states that when the efficiency of using a resource increases, its consumption often does not decrease but actually grows. In crypto, this can be seen, for example, in lower transaction fees, which lead to higher user activity.
JOMO (Joy of Missing Out)
JOMO is the opposite of FOMO (Fear of Missing Out) and describes a situation where investors feel no pressure to make quick decisions and are content with not participating in speculative markets.
K
Key Management
Key Management refers to the secure management of private keys, which are essential for accessing cryptocurrency assets. Keys can be stored in various forms, such as hardware wallets (Ledger, Trezor), multisig systems, or MPC (Multi-Party Computation), a method of splitting a key among multiple parties.
Probinex uses top-tier security technologies like Fireblocks, which combine MPC and institutional-grade key protection to ensure maximum security of user assets.

Open - The moment a trader enters the market by buying (long) or selling (short) a cryptocurrency.
Close - The moment when a trader sells an asset (for a long position) or buys it back (for a short position) to realize a profit or minimize a loss.
Over-the-Counter (OTC)
OTC (Over-the-Counter) trading means that a cryptocurrency transaction takes place outside of a traditional exchange, usually directly between two parties or through a specialized broker.
P
Performance Fee
Performance fee is a fee charged by investment platforms or fund managers based on the positive performance of a trading strategy.
Ponzi scheme
A Ponzi scheme is a fraudulent investment model where the returns of older investors are paid out of the deposits of new participants, not actual profits. The scheme collapses when there are not enough new investors to cover the promised returns.
Portfolio

Vesting
Vesting is a process where tokens are not released all at once, but gradually over time. It is used to protect against the bulk sale of tokens (dump) by founders or investors.
Volatility
Volatility measures the speed and range of price movements of a cryptocurrency. Bitcoin and altcoins are known for their high volatility, which means their price can rise and fall rapidly over a short period of time.
Volume
Volume refers to the total amount of cryptocurrency traded over a certain period of time (daily, weekly, monthly). High volume indicates strong liquidity and investor interest, while low volume may indicate less market activity.
W
WAGMI (We’re All Gonna Make It)
WAGMI is a popular crypto slang term that expresses optimism and belief in the success of the cryptocurrency community. It is used primarily during bull markets or in situations where investors believe their project will be successful in the long run.
