Greetings Bitcoiner,
Welcome to Issue #647 of Bitcoin Breakdown, where every Tuesday and Thursday, we bring you the latest must-read Bitcoin thought leadership articles and the newest tools and projects you should know about. But first, today’s Top Stories:
Hardware wallet users face phishing delivered through trusted email infrastructure, while Iran's exporters test Bitcoin and USDT as sanctions-resistant settlement rails. Germany, meanwhile, is considering a 25% tax that would remove the long-term holding exemption for newly acquired Bitcoin and make monetary use more cumbersome.

🛡️ Trusted Wallet Emails Become the Attack Vector
Trezor and BitBox warned users after attackers compromised third-party email infrastructure to distribute fake hardware wallet alerts. The messages used legitimate domains and authentication signals, while the bogus STM32 Entropy Vulnerability notice instructed recipients to perform a malicious update.
Why it matters: Sender checks are insufficient when attackers control real distribution infrastructure. Verify updates through an independently opened official channel, and never follow wallet instructions from an unsolicited email. Read more→
🇮🇷 Iran's Trade Rails Meet the Stablecoin Kill Switch
Iran's central bank reportedly loosened foreign-exchange enforcement so exporters can settle through domestic platforms using USDT and Bitcoin. Exporters can also reportedly finance imports directly from overseas earnings instead of selling foreign currency through the official platform.
Why it matters: USDT offers dollar stability but retains an issuer-controlled freeze switch. Bitcoin has no issuer or protocol-level freeze function, making neutral settlement a practical necessity when sanctions reach centralized money. Read more→
🇩🇪 Germany Targets Bitcoin's One-Year Tax Break
Germany's Finance Ministry reportedly proposed a 25% tax on gains from digital assets acquired after 2026, regardless of holding period. Older holdings would retain the current treatment, which generally allows qualifying gains to become tax-free after more than 12 months.
Why it matters: Clearer taxation still means more friction and less monetary use. Bitcoin advocacy should target the removal of taxes and transaction restrictions, not celebrate a better-defined state claim on private gains. Read more→
