Pius Sprenger Shorted Subprime. Now He Sees It Again.

— Pius Sprenger spent 25 years on Wall Street, worked directly under Greg Lippmann on Deutsche Bank's derivatives desk during the subprime crisis, and held a profitable short position for nearly three years while management dismissed him.

— The ABX index, co-built with Goldman Sachs and Bear Stearns in February 2007, became the tool that allowed investors to short subprime bonds—a market that had previously been impossible to short.

— Accountability collapsed after the 2008 crisis. Compliance officers diffused responsibility, bailouts socialized losses while profits stayed private, and traders who lost massive sums often saw career advancement rather than consequences.

— The power law—a mathematical model developed by Giovanni Santostasi and Steven Perino of the Scientific Bitcoin Institute—projects Bitcoin reaching $1M in 8–9 years and $7–8M in 17 years, based on adoption growing to the power of three and network value to the power of two.

— Wall Street's entry into Bitcoin via ETFs, STRC, and corporate treasury accumulation introduces negative price convexity and concentration risk; the $1.5T Bitcoin market is now flooded with structured paper that may determine underlying price.

— Firefish and Stamp Seed are essential tools to avoid counterparty risk in a financializing Bitcoin landscape.

— Avoid paper Bitcoin exposure. Not holding your own keys exposes you to Wall Street's negative price convexity and counterparty risk; self-custody via multi-sig eliminates this dynamic and aligns you with Bitcoin's founding ethos.

— Watch for liquidity crises in structured products. Short sellers exploit weakness in over-leveraged positions like STRC; a prolonged downturn could trigger forced selling and cascading losses that affect the broader market.

— The power law is falsifiable science. If Bitcoin fails to track the adoption and network value curves, the model breaks; however, Bitcoin's 17-year track record of resilience (dropping 70–90% and recovering to all-time highs) is historically unprecedented and supports the theory's plausibility.
