Stack BTC, a bitcoin treasury company promoted by Reform UK leader Nigel Farage, has seen its asset value plunge 15.48% since its March launch, resulting in a £565,000 loss. Farage, who invested £215,000 and owns 5.61% of shares, faces a standards probe over an undeclared £5m gift from crypto billionaire Christopher Harborne. Financial experts caution against celebrity-endorsed bitcoin treasury firms, citing extreme volatility, lack of diversification, and red flags such as frequent name changes. The case highlights political-crypto conflicts and regulatory scrutiny.
