Arbitrage betting not allowed
Sportbet.one's Terms could not be independently retrieved in full (the page appears JavaScript-rendered), so no verbatim arbitrage clause could be quoted. Real-world enforcement, however, is well documented: primary-source forum disputes from May 2024 through April 2026 describe the operator's internal "fraud detection" system flagging accounts for suspected arbitrage betting or multi-accounting, with the account restricted and the full balance confiscated rather than only the flagged bets voided — and the operator declining in each case to disclose which specific bets or evidence triggered the decision.
Payout & support complaints reported
A documented bitcointalk.org thread (June-July 2024) describes a player requesting self-exclusion by email on June 30, 2024 for gambling-addiction reasons; the automated self-exclusion system reportedly failed to take effect, and the player lost roughly 2,840 USDT on July 6-7, 2024 during the requested cool-off period. The player alleged inconsistent handling relative to other, reportedly-refunded cases; MISA had not issued a final ruling even after more than a year.

EUR 610.46 in winnings cancelled for alleged arbitrage on European basketball

Sportsbook Winnings confiscated / forfeited Priority B — funds frozen / prolonged review
What happened
Player reported betting on European basketball, including EuroLeague matches, before the account was reviewed and some bets were cancelled for alleged arbitrage. Deposits reportedly remained withdrawable, but EUR 610.46 in winnings were removed. The player denied arbitrage, arguing that ordinary bets on liquid basketball markets shouldn't justify cancelling all winnings. The complaint was posted inside the sportsbook's own Bitcointalk announcement thread; no operator answer was captured in this research pass.

How we source this

Cases here come from operator-facing complaint platforms (AskGamblers, Casino Guru) and public forum/Reddit reports. A verified case went through that platform's own review process; an unverified one is a community report we haven't independently confirmed. Visitors can also file a complaint directly (see below) — those go through our own review before publishing, kept separate from this sourced set. See How scoring works for the full methodology.
