Crypto Casino Glossary: 60 Terms Explained Simply

Crypto gambling borrows vocabulary from three worlds at once: casino floors, sportsbooks and decentralised finance. This glossary defines the sixty terms that come up most often, in plain language, in one alphabetical reference. It covers commonly confused pairs such as rakeback versus cashback and RTP versus variance, and flags terms where the same word carries very different risk depending on implementation.

Major Points Covered

• Sixty terms across casino, sports betting and DeFi vocabulary.
• Commonly confused pairs distinguished: rakeback and cashback, RTP and variance.
• BetFi-specific terms defined, including BFC, BFA, rank and the two pool types.
• Terms where the same word carries different risk, such as code-enforced versus manual lock-ups.
• Designed as a reference you can return to rather than read once.

Direct Answers to Common Questions

The most commonly misunderstood terms in crypto gambling are RTP, rakeback and lock-up. RTP describes a game's modelled return across millions of rounds rather than your session, and variance affects your evening far more. Rakeback pays a percentage of everything you wager regardless of outcome, while cashback pays only on net losses. And a lock-up enforced by smart contract cannot be broken, while one described in a document and executed manually depends entirely on the operator's conduct. Same word, materially different risk.

A

Airdrop — Free distribution of tokens to eligible wallets, usually rewarding early participation.

Allocation — The portion of total token supply assigned to a specific purpose, such as presale, team or liquidity.

APR / APTR — Annual Percentage Rate. The yearly return on a deposit before compounding.

Disposal — In tax terms, parting with an asset by selling, swapping or spending it. Often a taxable event.

E

Lock-up — A period during which tokens cannot be sold. Enforced by smart contract or, less securely, manually.

Mint — Creating new tokens. An uncapped mint function means total supply is not fixed.

Multi-sig — A wallet requiring multiple approvals before executing a transaction.

Frequently Asked Questions

What is the difference between RTP and variance?

RTP describes a game's modelled return across millions of rounds. Variance describes how widely results scatter around it. Two games at identical RTP can feel completely different, and variance affects your session far more.

What is the difference between rakeback and cashback?

Rakeback returns a percentage of everything you wager, win or lose. Cashback returns a percentage of net losses only, so a winning period pays nothing back.

What does BEP-20 mean?

It is the token standard on BNB Smart Chain, the equivalent of ERC-20 on Ethereum. The two are not interchangeable, and sending one to the other's address commonly loses funds.

What is TVL in a liquidity pool?

Total Value Locked: the aggregate value deposited into a protocol or pool at a given moment. It indicates scale, not safety or profitability.

Why does it matter how a lock-up is enforced?

Because a lock-up enforced by smart contract cannot be broken, while one described in a document and executed manually depends on the operator's conduct. Same word, materially different risk.
