TODAY’S TOP STORIES

🇧🇷 Brazil's Biggest Bank Recommends Up To 3% Bitcoin Allocation

Itaú Unibanco, Brazil's largest private bank, is telling investors to allocate 1% to 3% of their portfolios to bitcoin for diversification and currency hedging. Itaú Asset Management's research highlights bitcoin's low correlation with traditional assets and its potential to mitigate risks amid geopolitical tensions and monetary policy shifts. The bank launched a dedicated Bitcoin and crypto division in September and already offers a Bitcoin ETF and pension fund with digital asset exposure, with more products planned. Atlas21

🎰 Solo Miner Hits Bitcoin Jackpot Against 82-Year Odds

A solo Bitcoin miner with just 270 terahash per second of computing power beat astronomical odds to mine block 927,474 and claim the full 3.133 BTC reward worth $285K. Using CKpool's solo mining software, the miner had roughly a 1-in-30,000 chance per day of success – equivalent to once every 82 years. The tiny operation represents just 0.00002% of Bitcoin's total network hashrate, proving anyone can win the ultimate proof-of-work lottery. The Block

⚛️ Bitcoin OGs Ready to Buy the Quantum Dip

Willy Woo argues long-term Bitcoin holders would snap up any flash crash caused by a quantum computer hacking Satoshi Nakamoto's 1M BTC stash. While about 4M BTC in older pay-to-public-key addresses remain vulnerable to future quantum attacks, newer wallet types are protected. Bitcoin OG Adam Back argues the quantum threat is decades away, giving plenty of time to adopt post-quantum cryptography standards that already exist today. Cointelegraph

QUICK MEDIA

• BTC Sessions analyzes how US economic indicators (including record bankruptcies, plummeting manufacturing employment, and Depression-era consumer sentiment) are forcing the Federal Reserve to resume quantitative easing, potentially disrupting Bitcoin's traditional four-year cycle and triggering a delayed euphoric price surge as institutions finish accumulating (Dec 13 | 21:24 min watch).

• Anita Posch of Bitcoin For Fairness, after 5 years working across African countries, argues that most Bitcoin education initiatives amount to 'adoption theater' rather than real impact, and calls for locally-built solutions prioritizing privacy and self-custody to prevent ‘neocolonial’ capture of African Bitcoin resources (Dec 13 | 10:26 min watch).
