BetOnline.ag is one of the longest-running offshore sportsbooks serving U.S. bettors, having operated since the early 2000s. It occupies a distinct space in the market as a book that caters to a broad audience while maintaining relatively sharp lines across major sports. Unlike some offshore competitors that aggressively limit winning players, BetOnline has built a reputation for being more tolerant of sharp action, though it doesn't quite match the freedom offered by books like Pinnacle or Circa. Its offshore status means it operates outside U.S. state-by-state regulatory frameworks, which carries inherent trade-offs around deposit protections and legal recourse that bettors should weigh carefully.
In terms of strengths, BetOnline offers an extensive betting menu that spans major U.S. sports, international markets, esports, politics, and entertainment props. Lines are posted early compared to many competitors, and the book accepts cryptocurrency deposits and withdrawals with minimal friction — a significant advantage for bettors who prioritize transaction speed and privacy. The platform also features reduced juice promotions on select markets and offers competitive odds on NFL and NBA sides and totals. On the downside, the user interface feels dated compared to modern state-regulated sportsbooks, and payout speeds for non-crypto methods can be inconsistent. Customer support has drawn mixed reviews, and the overall betting experience lacks the polish of DraftKings or FanDuel.
BetOnline is best suited for experienced bettors who value market breadth, early line access, and crypto-friendly banking over regulatory protections and sleek design. It's a solid option for multi-sport bettors and those who want to shop lines across offshore and domestic books. Casual recreational bettors may find the interface less inviting, but for anyone comfortable navigating the offshore landscape, BetOnline remains a reliable and well-established option with a track record spanning two decades.

BetOnline offers payouts via cryptocurrency (fastest, usually same day), check by courier (7–14 days), and bank wire (5–7 days). They provide one free payout per month, with fees for additional withdrawals depending on the method.
What is vig (vigorish) in sports betting?
Vig — short for vigorish, also called juice or overround — is the margin a sportsbook builds into its odds. It's the difference between the true probability of an outcome and what the odds imply. Lower vig means you keep more of your winnings on every bet. For example, a standard -110/-110 line has about 4.76% vig.
How often is this data updated?
We pull fresh odds from The Odds API three times per day — at 6:00 AM, 2:00 PM, and 10:00 PM UTC. Each snapshot captures the latest lines from every sportsbook that has posted odds. The timestamp at the top of the page shows the most recent refresh.
How is the vig grade calculated?
Each sportsbook is graded on a letter scale based on average vig: A+ (under 2%) is exceptional, A (2–3%) is excellent, B+ (3–4%) is above average, B (4–5%) is the industry standard, C (5–6%) is below average, and D (above 6%) indicates high-juice markets.
Why does lower vig matter for bettors?
Lower vig directly impacts your long-term returns. A bettor placing $1,000 per week at a book with 4% vig loses roughly $40/week to the house edge. At 2% vig, that drops to $20/week — a $1,040 difference over a year. For serious bettors, shopping for lower vig is one of the most reliable ways to improve profitability.
What sportsbooks do you track?
We track both regulated US sportsbooks (DraftKings, FanDuel, BetMGM, Caesars) and offshore books (Bovada, BetOnline, MyBookie, BetUS, LowVig.ag, BetAnySports). Data comes from The Odds API, which aggregates real-time lines from licensed sources.
How We Calculate These Numbers
- Data Source
- All odds on this page come from The Odds API, which aggregates real-time lines from licensed US and offshore sportsbooks. We track moneyline, spread, and totals markets across every sport with active betting lines.
- Update Frequency
- We pull a fresh snapshot of every tracked market three times per day — at 6:00 AM, 2:00 PM, and 10:00 PM UTC. Each snapshot captures the latest lines from every sportsbook that has posted odds for a given event. The timestamp at the top of each page tells you exactly when the data was last refreshed.
- Vig Calculation
- Vig (short for vigorish, also called juice or overround) measures the margin a sportsbook builds into its odds. We calculate it by converting the odds on each side of a market to implied probabilities, summing those probabilities, and subtracting 100%. For example, a market priced at -110/-110 implies 52.38% on each side — a total of 104.76%, meaning a vig of 4.76%. Lower vig means better value for bettors because you keep more of your winnings.
- Per-Market Breakdown
- We compute vig separately for each market type: moneyline (h2h), point spreads, and totals (over/under). The "average vig" shown for each sportsbook is the mean across all market types weighted by the number of events sampled in each market.
- Grading Scale
- Every sportsbook receives a letter grade based on its average vig: A+ (under 2%) is exchange-level pricing. A (2–3%) is very competitive. B+ (3–4%) is above average. B (4–5%) is the industry standard — a -110/-110 line is 4.76%. C+ (5–6%) is slightly below average. C (6–7%) is below average. D (7–8%) is high vig. D− (8–10%) is very high vig. F (10%+) is predatory pricing. See the full Vig Index Methodology for formulas, worked examples, and known limitations.
- Trend Tracking
- We store daily snapshots for 30 days, allowing us to show 24-hour and 7-day vig trends. A downward trend (improving) means sportsbooks are tightening their lines — often in response to increased competition or higher betting volume as a season heats up.
