Signal Messenger using Bitcoin, Funding developers, Perspectives of Jack, Saylor & Elon

— Signal's potential integration of Cashew/eCash requires solving critical unknowns, particularly around who operates the mint and how Signal avoids becoming a Money Services Business (MSB) while maintaining privacy.

— The distinction between self-custody and token-based systems remains contested; Cashew tokens are bearer instruments stored on relays, not self-custodied Bitcoin, though proponents argue users retain key control.

— Square's Bitcoin stickers on merchant terminals could shift public perception of Bitcoin as currency rather than asset, creating psychological momentum for adoption even before widespread spending occurs.

— LightSpark's Grid announcement positions Bitcoin and Lightning as neutral settlement layers between existing real-time payment networks (PIX, UPI, etc.) rather than as consumer-facing stable coins.

— Open networks (Bitcoin, Lightning) will ultimately outcompete closed proprietary systems, though regulatory and corporate inertia may delay adoption for several more years.

— Merchant adoption remains friction-heavy; conversations with local businesses revealed complexity concerns and unfamiliarity with Bitcoin, even in tech-forward areas.

— Gold has surged from ~$1,600 to $4,300 per ounce in recent months, driven partly by central bank purchases (China, Russia) and potential U.S. Treasury revaluation.

— Bitcoin has declined from ~$125,000 to $105,000 recently; one hypothesis suggests strategic Bitcoin acquisition by governments may deliberately suppress price during accumulation phases.

— Costco is reportedly selling out of physical gold bullion, indicating retail demand for tangible stores of value during economic uncertainty.

— Push merchant adoption pragmatically: Approach merchants with specific ease-of-use messaging (single toggle in Square) rather than technical Bitcoin explanations; physical demonstrations of Bitcoin as "digital cash" may resonate better than abstract concepts.

— Prove solutions outside Signal first: Rather than lobbying Signal to integrate an incomplete Cashew implementation, build working demonstrations of non-custodial, low-friction Bitcoin/eCash spending and prove demand independently.

— Monitor Grid and inter-network bridges: LightSpark's Grid API approach (connecting PIX, UPI, Bitcoin settlement) represents a pragmatic infrastructure play that may accelerate adoption among merchants and developers faster than consumer stable coin narratives.
