Greetings Bitcoiner,
Welcome to Issue #675 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:
Jeonbuk Bank opens South Korea's first bitcoin-backed corporate loans, Binance closes its mining pool without giving a specific reason, and the FSB warns the G20 that a stablecoin run could spill into banks. Bitcoin works as collateral, mining needs no gatekeeper, and fiat's counterparty risk is easier to escape when you hold your own keys.

🏦 Jeonbuk Bank Opens Korea's First Bitcoin Loans
Jeonbuk Bank, a regional lender owned by JB Financial Group, has begun offering won loans backed by bitcoin, reported as the first such bank loan in South Korea. For now the loans are limited to corporate customers raising working capital, and bitcoin is the only eligible collateral because of its liquidity and trading volume.
Why it matters: A Korean bank built this inside current rules, while a specialized custodian holds the collateral, which means won credit comes with a counterparty holding your keys. Other Korean lenders now have a template, and bitcoin is the only collateral this bank trusts. Read more→

⛏️ Binance Shuts Its Mining Pool and Won't Say Why
Binance will discontinue Binance Pool, Pool Savings, Cloud Mining and Transaction Accelerator on November 10 at 07:00 UTC, and hashrate sent after that cutoff will not be credited. The notice cited only an ongoing review of products and services and gave no specific reason, so miners pointing hashrate at Binance Pool must repoint before the cutoff.
Why it matters: Miners who parked rewards with Binance now wait on its risk and compliance checks to get paid, which shows what custodial mining really means. Binance keeps the discretion, while miners learn a gatekeeper can close the pool without giving a reason. Read more→

⚠️ FSB Warns G20 a Stablecoin Run Could Hit Banks
The Financial Stability Board told the G20 that a run on a global stablecoin could spill into the traditional financial system through reserve-asset fire sales and bank deposit withdrawals. The FSB also says holders' legal claims may be unclear in stress and insolvency, because arrangements spread across multiple entities and regulatory regimes remain untested.
Why it matters: Stablecoins brought fiat's counterparty risks onto the blockchain, with reserve assets the FSB says could face fire sales in a run. Bitcoin has no issuer to run on, which makes self-custody of sats the escape hatch that skips the redemption queue. Read more→
