Bitcoin Offline Transaction Demo: Mesh Radio Broadcast Transaction Directly to Mempool at BOSS Summit
April 4th — Developer Bala pulled off a live demo of a fully offline Bitcoin transaction at the recent Bitcoin Open Source Summit (BOSS Summit) in Dharamsala, India, wowing the Bitcoin community.

Just pure radio waves: the transaction broadcast instantly, landed straight in the Bitcoin mempool, and seamlessly moved from “off-grid” to “on-chain.”

Analyst: Bitcoin ETF Could Surpass Gold ETF in Size, Highlighting Value of Allocation
On April 4th, Bloomberg ETF analyst James Seyffart said Bitcoin spot ETFs are poised to surpass gold ETFs in assets under management (AUM) as market demand continues to grow.
Seyffart noted Bitcoin has more diverse portfolio applications: it functions as "digital gold" and a store of value, while also offering asset allocation diversification, trading liquidity, and growth-risk asset traits. Gold, by contrast, has a relatively narrow investment logic.
Fund flows reflect a shift in investor preferences: U.S. gold ETFs saw significant outflows in March, with net outflows of ~$2.92 billion. Over the same period, Bitcoin spot ETFs attracted ~$1.32 billion in net inflows.
Despite the divergence in fund flows, Bitcoin and gold prices have tracked closely recently. Over the past 30 days, Bitcoin is down ~8.07% while gold has fallen ~8.25%.
Market observers believe Bitcoin ETFs are transitioning from "alternative assets" to mainstream allocation tools as investor demand for digital

Trump Proposes $1.5 Trillion Defense Budget, Setting New High in U.S. Modern History
April 4: U.S. President Donald Trump released an outline of his Fiscal Year 2027 budget proposal, calling for a record $1.5 trillion in defense spending—marking a new modern-era high for the U.S.
Under the plan, roughly $1.1 trillion would go to the U.S. Department of Defense, with an additional $350 billion earmarked for critical ammunition buys, defense industrial base expansion, and other initiatives. The budget also funds key military programs like shipbuilding and the "Golden Dome" missile defense system.
The White House notes the proposal would keep overall spending caps in place while cutting roughly $73 billion in non-defense funding—impacting areas such as education and environmental protection. It also includes funding for new entities, including the National Fraud Investigation Agency, led by Vice President JD Vance.
The budget is currently a summary version; full details have not yet been released. The Republican-controlled Congress must finalize deliberations and
