Paul Withers has resigned as the chief executive of Stack BTC, a bitcoin company promoted by British politician Nigel Farage. Stack BTC, which relaunched in March 2023, aims to position itself as a bitcoin treasury and venture capital firm after its predecessor, Kasei Investment Holdings, was liquidated last year due to adverse market conditions and an inability to raise capital. The company launched with $6.1 million (£4.5 million) in share capital but returned $3.4 million (£2.5 million) to shareholders upon liquidation. Withers, who has been associated with Farage since 2021, has been replaced by David Galan, a former real estate executive, who is expected to bring significant experience to the role. Farage's involvement, including a £215,000 investment, has raised questions about the company's management and its appeal to investors. Industry experts have expressed skepticism regarding the company's viability, with some viewing it as a public relations exercise rather than a sound investment opportunity.
