Sportsbet.io is a cryptocurrency gambling and sports betting platform operated by mBet Solutions N.V. under the Yolo Group umbrella, licensed in Curaçao. On June 22, 2024, blockchain investigator ZachXBT publicly identified that the platform's hot wallets were drained of approximately $3.5 million in USDT and TRX, attributing the attack to the same threat actor who hours later stole an estimated $55 million from Turkish exchange BtcTurk, with stolen funds allegedly commingled between both hacks. The platform has drawn ongoing scrutiny for operating in regulatory grey markets, serving users in jurisdictions where it holds no local license, and for systemic user complaints involving account closures and fund seizures following wins. Yolo Group founder Tim Heath confirmed in 2025 that the brand is being wound down in favor of fully regulated markets.

Metawin is an offshore crypto casino and gaming platform licensed under the Anjouan (Comoros) gaming authority, operated by Asobi N.V. from Curacao, and founded by Richard 'Skel' Skelhorn. On November 3, 2024, the platform suffered a significant hot wallet exploit across Ethereum and Solana blockchains resulting in approximately $4 million in stolen funds, with blockchain investigator ZachXBT tracing the stolen assets to KuCoin and a nested HitBTC service across more than 115 attacker-linked addresses. The CEO subsequently claimed to have personally covered the losses, restoring withdrawals for approximately 95% of affected users, though the platform's offshore jurisdictional status and the underlying security vulnerability raise ongoing concerns.

Spartans Bet (spartans.com) is a crypto betting and casino platform launched in 2025, operated by Nexus International Entertainment Ltd, a company registered in Belize and licensed under the disputed Anjouan (Comoros) gaming authority. On-chain investigator ZachXBT alleged in 2025 that the platform's suspected co-founder, Gurhan Kiziloz, is also the hidden operator behind BlockDAG Network, a project ZachXBT claims raised over $300 million from retail investors through deceptive social media advertising and misappropriated presale funds via Middle Eastern OTC channels. Spartans makes prominent 'provably fair' claims that lack independently verifiable third-party audit documentation, and the platform carries a below-average safety index of 6.4/10 from casino.guru, with user complaints citing refused withdrawals and unfair bonus terms.
