A thirty-year currency trader’s case for where the world’s capital is going. Douglas Borthwick spent three decades trading the world’s currencies at Morgan Stanley, Merrill Lynch, and Standard Chartered. He watched the same thing happen every time a government’s promise broke: capital left, faster than anyone could stop it. Thailand in 1997. Argentina. Iceland. The pattern never changed. Bitcoin: The Capital Singularity is a trader’s argument, not a believer’s. It makes one claim and defends it with numbers: capital converges over time on the hardest, most portable money available, and for the first time that money answers to no one. Borthwick names exactly what would prove the thesis right, and exactly what would prove it wrong. No price targets. No hype. Inside: What thirty years on a trading desk teaches about money that fails - The Capital Singularity, stated so it can be tested, not just believed - The 2026 evidence: ETF flows, corporate treasuries, sovereign reserves, and the honest risks - Why the drawdowns are the entry fee, and how to size for what you cannot time - Custody, inheritance, and holding your own keys, without the slogans Second Edition, revised and updated with the 2026 numbers. For the analytical reader who wants the case, and the receipts.
