Arbitrage betting — often called arbing — is the practice of placing opposing bets on all outcomes of the same event across different sportsbooks to guarantee a profit regardless of what happens. Because different bookmakers price the same event differently, mathematical profit opportunities exist. With cryptocurrency, arbing is faster, cheaper and more accessible than ever.
How Arbitrage Betting Works
An arbitrage opportunity exists when the combined implied probabilities of all outcomes from different bookmakers totals less than 100%. The excess represents guaranteed profit.
Example: A football match, Chelsea vs Arsenal.
- Platform A offers Chelsea to win: 2.20 (implied probability: 45.5%)
- Platform B offers Arsenal to win: 2.35 (implied probability: 42.6%)
- Platform C offers the draw: 4.10 (implied probability: 24.4%)
- Total implied probability: 45.5 + 42.6 + 24.4 = 112.5% — normally no arb
For an arb to exist, you need the total to be under 100%. When that happens, calculated stakes on each outcome guarantee profit.
Calculating Arbitrage Stakes
For a two-outcome market (e.g., Asian Handicap — no draw):
- Platform A: Team A at 2.10 | Platform B: Team B at 2.15
- Implied total: (100÷2.10) + (100÷2.15) = 47.6 + 46.5 = 94.1% — arb exists!
- Profit = 100 – 94.1 = 5.9% guaranteed regardless of outcome
- For a 200 USDT total stake: profit = 200 × 0.059 = 11.8 USDT guaranteed
Why Crypto is Ideal for Arbing
- Instant deposits: traditional arbing is limited by slow bank transfers. Crypto deposits confirm in minutes — meaning you can act on arb opportunities before odds change
- No bank blocks: banks often flag gambling transactions. Crypto transactions go through unimpeded
- Low fees: minimal transaction costs preserve arb margins
- Multiple accounts: crypto makes running 5 to 10 sportsbook accounts easy and economical

Risks and Limitations of Arbing
- Account restrictions: traditional bookmakers often limit or close accounts of successful arbers. Crypto platforms are generally more tolerant but it can still happen
- Odds movement: by the time you place both sides, odds may have changed — eliminating the arb or creating a loss
- Time-sensitive: arb opportunities last minutes. You need fast deposits and quick decision-making
- Small margins: typical arb profits are 1% to 5% per opportunity — requires significant volume or stake sizes
- It is not truly risk-free: human error (wrong amount, wrong selection) eliminates the arb and creates potential losses
Responsible Arbing
Arbitrage betting is a legitimate strategy but requires careful execution and realistic expectations. Do not stake more than you can afford on any single arb — execution errors can lead to losses.
