ETH Climbs 13% Weekly as $1B Floods Bitcoin ETFs

Ether traded at $2,312.59 on Monday, up 1.56% in 24 hours and 13% over the past week. The rally came as part of a broad crypto advance fueled by $767 million in spot ETF inflows and speculation around a ceasefire deal, producing the widest risk-on move since before the conflict began. Bitcoin tested $75,000 before retreating, XRP surged 11%, and Solana added 9.7%.

Bitcoin's Fragile Surge

Bitcoin posted a rare eight-day winning streak last week and briefly cleared $75,000, a six-week high. The move didn't hold. Prices slipped back below that level as the rally's derivatives-led structure showed cracks, with leveraged longs unwinding quickly once momentum stalled.

US-listed spot Bitcoin ETFs recorded six consecutive days of inflows totaling nearly $1 billion since March 9, providing a real demand floor. But implied volatility in Bitcoin options remained notably calm even as equity, oil, and bond markets saw panic hedging drive traditional vol indexes sharply higher. Bitcoin traders, for now, aren't flinching.

Strategy (formerly MicroStrategy) bought seven weeks' worth of new Bitcoin supply in a single week, outpacing post-halving issuance by 700%. That kind of concentrated demand has analysts modeling price targets as high as $400,000, though the comparison assumes the pace continues. It won't indefinitely.

Polymarket Blocked in Argentina

A Buenos Aires court ordered Polymarket blocked across Argentina, the latest in a string of regulatory moves against prediction markets worldwide. The platform, which saw record volumes during the 2024 US election cycle, now faces access restrictions in a country with one of Latin America's highest crypto adoption rates.

The ban reflects a broader pattern. South Korea is drafting crypto seizure rules for police after custody lapses. The SEC published a request for comment on whether its OTC broker-dealer rule (15c2-11) should extend to certain crypto assets. Regulatory infrastructure is being built in real time, and not all of it is friendly.

DeFi Lobby Recalibrates

The DeFi Education Fund and Beba voluntarily dismissed their airdrop-related lawsuit against the SEC. The filing was without prejudice, leaving the door open to refile later. The move signals a tactical shift: with a more crypto-sympathetic SEC chair in place and legislative momentum building, litigating may be less useful than lobbying.

That lobbying is active. Stand With Crypto stakeholders from multiple states sent a letter to the Senate Banking Committee urging DeFi protections and stablecoin reward provisions in pending legislation. The push comes as Circle and Tether compete for dominance in a stablecoin market that lawmakers seem increasingly willing to formalize.

XRP Breaks Through, Market Structure Shifts

XRP flipped BNB by market cap after smashing through $1.50 resistance on a 125% volume spike, reaching a $93.4 billion valuation. Binance futures open interest in XRP has climbed 59% since October, even though the price remains 58% below its all-time high. The gap between positioning and price suggests traders are betting on a larger move ahead.

Corporate Moves

Messari replaced its CEO and cut staff. New chief Diran Li announced a pivot toward AI-powered research tools aimed at institutional clients, joining a growing list of crypto data firms chasing the AI premium. Whether that premium materializes in revenue or just in pitch decks is an open question.

Cango, the Chinese auto platform turned Bitcoin miner, reported a $452.8 million net loss in its first full year of mining operations. The company sold bitcoin to service debt and fund a pivot into AI. The pattern is familiar: mining losses subsidized by narrative rotation.

Crypto.com partnered with KG Inicis, a major South Korean payments processor, to enable crypto payments for tourists at local merchants. The integration represents incremental progress in real-world crypto utility, targeting foreign visitors rather than domestic users.

Miami Builders Eye Stablecoin Legislation

The Senate Banking Committee pressure campaign over DeFi protections and stablecoin rewards has direct implications for Miami's growing concentration of stablecoin infrastructure firms. Zero Hash, headquartered in Chicago but with a significant Miami engineering presence, processes stablecoin mint-and-burn operations for fintech platforms and would benefit directly from clearer federal rules. The company's infrastructure sits at the intersection of the GENIUS Act provisions that Stand With Crypto stakeholders are pushing senators to preserve.

Miami's role as a stablecoin corridor continues to expand. Circle held its last major partner event in the city, and several Miami-based fintechs building on USDC rails are watching the Senate markup closely. If the legislation passes with DeFi-friendly provisions intact, Miami stands to absorb a disproportionate share of the compliance-ready stablecoin businesses that follow.

On the local calendar, Miami Dade College's Wolfson Campus hosts its monthly Web3 Builders meetup this Wednesday, with this month's session focused on tokenized real-world assets. Attendance has grown steadily since the series launched in late 2025, reflecting the city's shift from conference tourism to sustained builder activity.

SEC Watch

The SEC's request for comment on crypto's treatment under Rule 15c2-11 is narrow but significant. The rule governs how broker-dealers handle OTC equity quotations. The Commission proposed limiting it to equity securities only, then asked whether certain crypto assets should be included. The framing suggests the agency is at least considering a path that doesn't lump all tokens into existing equity frameworks.

Coinbase and Kraken, both of which operate OTC desks for institutional clients, would be directly affected by whatever the SEC decides here. Comment periods tend to be where policy is shaped before it's set.
