Last week in crypto: Technical progress, volatility and regulatory pressure

Last week (December 1–7, 2025) brought a mix of technical progress, market volatility and fresh regulatory pressure — a snapshot of an industry still maturing fast.

Markets: Bitcoin slid early in the week — dropping roughly 5–8% on December 1 as risk-off flows hit crypto — before a partial recovery later in the period. //Reuters

Ethereum & tech: Ethereum’s much-anticipated Fusaka upgrade went live on December 3, 2025, aiming to boost throughput and lower costs for Layer-2s; early on-chain metrics showed notable ETH inflows around the upgrade. //CoinGecko

Institutional flows: Corporates remained active — Strategy (formerly MicroStrategy) reported a nearly $1 billion Bitcoin purchase during Dec 1–7, adding 10,624 BTC and signalling continued institutional appetite for on-balance-sheet bitcoin exposure. //Barron's

Regulation & policy: Regulators kept up the scrutiny. The U.S. SEC ran a high-profile roundtable on financial surveillance and privacy (Dec 5), underscoring evolving enforcement and transparency expectations for crypto firms. Meanwhile Brussels drafted stronger centralized oversight proposals aimed at unifying crypto supervision under EU authorities. //SEC

Why it matters: Tech upgrades like Fusaka progress Ethereum’s roadmap toward greater L2 scalability, but short-term price action remains sensitive to macro and regulatory headlines. Institutional buys provide a structural demand signal, while policy moves in the U.S. and EU show regulators are moving from ad-hoc responses toward formalized frameworks.

Outlook (brief): Expect more chop — upgrades and institutional flows will keep headlines positive, but regulation and macro risk will continue to drive volatility through December.

State of Solana: Last 30 Days Overview

 Over the past month, SOL has hovered around the US $130–$140 range. According to recent market updates, SOL dipped by ~1% on December 5 while holding near $137.  That drop followed a slightly stronger 4% surge a day earlier, which was attributed to increased institutional inflows.  While volatility remains, many analysts argue SOL is forming a “defensive base” — with key price support around $130.  In short, SOL hasn’t been making new highs recently — but price action seems relatively stable, with speculative interest rising around institutional developments and network-level events. Recent News & Institutional / Ecosystem Developments Several developments in the last month have stirred renewed interest in Solana: A big institutional signal: a new multi-crypto ETF ( EZPZ ETF ) — launched December 1 by Franklin Templeton — added SOL among its holdings, giving broader institutional access to the token.  Cross-chain integration: Base — the Layer-2 network...
