The platform's Lock contract suffered a critical access-control vulnerability in December 2024 that allowed any caller to drain tokens, resulting in an estimated $85,700 loss. Multiple independent scam-detection services rate associated BTC24H web domains as high-risk or outright malicious, and the project's tokenomics — 5% daily returns for 30 days via a multi-level referral structure — exhibit structural characteristics consistent with unsustainable high-yield investment programs.","timeline":[{"date":"2024-11-01","event":"Domain bitcoin24h.net registered (approximate, based on Scamadviser analysis noting November 2024 registration date).","source":""},{"date":"2024-12-01","event":"BTC24H token (0xbcde600B) deployed on Polygon PoS; Uniswap v3 liquidity pools created with near-zero liquidity.","source":""},{"date":"2024-12-16","event":"BTC24H Lock contract on Polygon exploited via missing eligibility check in the 'claim' function; estimated loss of $85,700.
