The FCA has issued a warning against Retardio, a Solana-based meme coin, stating it is unauthorized to offer financial services in the UK, leaving users unprotected under the Financial Ombudsman Service or FSCS. Despite the warning, Retardio's token price rose by 16%, reaching $0.09011, while the project boasts over 11,000 Telegram members and an NFT collection. The FCA continues to tighten oversight in the digital asset sector, recently cautioning against another unauthorized project, Pump.fun.
