Marcus Lindberg is a Stockholm-based crypto-trader-turned-casino-analyst who has spent the last seven years following the on-chain side of online gambling. He started running custom node infrastructure in 2018, moved into security audits for early DeFi protocols, and now writes about wallet hygiene, custody trade-offs, and how anonymous casinos actually handle (and sometimes mishandle) player funds. Marcus reviews casinos the way he reviews smart contracts: he reads the fine print, tests the withdrawal stack with small probe-deposits, and watches the chain. He has a particular interest in self-custody flows, KYC-optional platforms, and the operational security mistakes that get retail players doxxed. When he is not benchmarking deposit confirmations across BTC, ETH, and Tron, he is reverse-engineering bonus contracts to see what is actually enforceable on-chain.
