  2. The OCC gave conditional national trust charters to five crypto-related firms (Paxos, Ripple, BitGo, Fidelity, and Circle’s bank), imposing detailed compliance conditions and drawing criticism from banking and state regulators about oversight and risks.

Stimulation Theory

Malt Liquidity • 24 implied HN points • 15 Jan 26
💰 Finance Fintech

  3. Stimulation theory: aim for an optimal threshold of information so you can make informed decisions without getting fried by toxic constant flow, and build information pipelines that filter signal from noise.
