๐ SEC Clears a Path for Self-Custodial Wallet Builders
The SEC's Division of Trading and Markets issued guidance exempting self-custodial crypto trading interfaces from broker-dealer registration if they function as neutral tools. The five-year framework prohibits trade recommendations, investment advice, and asset custody.

From regulation to accumulation...
๐ฐ Strategy's STRC Prints $1 Billion in a Single Day
Strategy's STRC preferred stock hit $1 billion in single-day volume on Monday, with 100% clearing above the $100 par value. An 8-K filing confirmed 13,927 BTC acquired at $71,902 average for $1.001 billion last week, bringing total holdings to 780,897 bitcoin.
Why it matters: This is the first billion-dollar buy funded entirely through STRC preferred shares, not common stock. The 11.5% dividend is the cost of accumulating regardless of conditions. Read moreโ

๐ฆ Banks Fire at Stablecoins, Miss the Real Threat
The American Bankers Association is pushing back on a White House study that found banning stablecoin yield would boost lending by just $2.1 billion. The lobby warns yield-paying stablecoins scaling to $2 trillion could drain deposits from community banks.
Why it matters: Their panic exposes the fragility of banks that need regulatory protection from free market competition. While they lobby over stablecoins, they will not see Bitcoin coming. Read moreโ
Poll #520: Will Strategy hold 1 million bitcoin by end of 2026?



Jimmy Song, author of 'Programming Bitcoin', argues that a third Bitcoin node implementation is essential to break the monopoly dynamics of Bitcoin Core, foster market-driven accountability, improve network resilience, and give users a genuine voice through software choice rather than political tribalism (Apr 13 | 7 min read).

John of Ten31 argues that despite surging mainstream enthusiasm, blockchain-based stablecoins face insurmountable scaling, interoperability, and counterparty limitations, and that long-term digital dollar infrastructure will inevitably migrate toward proprietary, database-driven systems controlled by issuers like Tether and Circle (Apr 10 | 60 min read).
Handre van Heerden, in a Substack series on buried economic thought, argues that Ludwig von Mises' 1912 Austrian business cycle theory accurately predicted every major central bank-driven boom-bust cycle, yet was systematically ignored by policymakers in favor of Keynesian interventionism (Apr 10 | 7 min read).

Jesse Tevelow, author of 'Life After Bitcoin', argues that Iran's demand for BTC tolls at the Strait of Hormuz signals a pivotal game-theoretic shift, positioning Bitcoin as a neutral, censorship-resistant settlement layer that nation-states are increasingly compelled to adopt over fragile fiat alternatives (Apr 9 | 16 min read).
