Bitroo, a Bitcoin cloud mining project founded by An Xinxin, is under scrutiny after allegations surfaced regarding its refusal to process user withdrawals since April 2024. The project, which promoted computing power packages in Telegram groups, reportedly left investors unable to redeem their funds, with some losing hundreds of thousands to millions of USDT. Despite claims of North American mining resources, no mining machines have been verified, and the platform has not officially responded to redemption requests. Amid these issues, An Xinxin has reportedly initiated a new quantitative fund project, Select Official, seeking to raise funds from clients. The influencer "Encryption Fearless" highlighted these developments, urging users to exercise caution and be aware of potential scams.
