Just a reminder that exactly 16 years ago, a website was created so that anyone could claim 5 bitcoins for free! The user only needed to enter their receiving address, solve a captcha, and that was it! They received 5 BTCs for free. The site was created on May 28, 2010, by Gavin Andresen to help spread BTC adoption without the need for mining. He funded the site with 1,100 bitcoins, in addition to donations. In total, the site distributed 19,700 BTCs, or in other words, almost two pizzas! It was shut down in 2012. It was the Homestead Act of 1862, in which President Abraham Lincoln signed the law to encourage the settlement of the American West. Any citizen over the age of 21 could claim about 160 acres (65 hectares) of public land. #BTC #Bitcoin

Iran has proposed a fee of $1 USD per barrel of oil in transit through the Strait of Hormuz, payable exclusively in Bitcoin. This would mark the first time Bitcoin is explicitly used as a tool to resolve a geopolitical conflict. - Censorship Resistance: Unlike the SWIFT system or gold held in custody, Bitcoin functions as a permissionless settlement layer that cannot be censored or confiscated by governments. - Game Theory: The protocol utilizes Game Theory and a Proof-of-Work mechanism to create a Nash Equilibrium, where honesty is the most profitable strategy for all participants. - Hard Money: Because Bitcoin requires a real expenditure of energy and cannot be printed, it imposes financial constraints that make it difficult to fund conflicts through currency debasement. Wars have historically been financed by printing money without immediate consequences. By imposing limits on inflation, Bitcoin could make conflicts harder to sustain, rendering war so costly that cooperation becomes more viable than confrontation. #bitcoin #BTC

Exactly 13 years ago, #Bitcoin mining changed forever! Jeff Garzik received the 1st ASIC from China. The next day he posted: "After 20h, 14.98832170 BTC mined!" The ASIC era had begun. #BTC #nostr

In the past 100 years, stock values have been rising in dollar terms, but have remained flat in gold and are falling in Bitcoin. At this rate, in a few years, someone with just a few BTC will be able to buy the entire fortune you’ve spent your whole life building through stock investments! #bitcoin #btc #nostr

Exactly 15 years ago, a solution was proposed for CPU miners who had to compete with GPU miners on the Bitcoin network. On November 27, 2010, Bitcointalk forum member “slush” announced that he had designed the first Bitcoin mining pool. Before that, individual miners using CPU-based systems faced intense competition, especially from those mining with GPU-equipped computers. He proposed a solution to combine the computing power of multiple CPUs. The goal was to increase the chances of finding a block and thus earn a proportional reward. By joining the mining pool, CPU miners could enjoy more consistent payouts compared to solo mining, where finding a block could take weeks or even months. For reference, last week (November 21), a solo miner hit the jackpot and found the hash to mine block 924,569. His equipment produced a hashrate of 1.2 TH/s, while the Bitcoin network that day was at 1.14 ZH/s. That means his daily odds were 1 in 6.6 million, or roughly 18,000 years of mining to find a single block. At least since then, it has been possible to connect to a mining pool and get paid proportionally, instead of waiting 18,000 years… #btc #bitcoin #nostr

Como seria um ataque hacker ao protocolo do Bitcoin? É possível?

O advento da moeda digital chamou a atenção de hackers, mas um ataque ao protocolo do Bitcoin ainda pode acontecer?

Want to know if LLM models are better than octopuses, fish, or monkeys at picking assets to invest in? That’s (maybe not) what Alpha Arena was created for. Since October 17, six AI models have been competing to see who invests best. Competition Rules: - Initial Capital: each model received $10,000 - Market: Cryptocurrency perpetual contracts on Hyperliquid - Objective: Maximize risk-adjusted returns - Transparency: All model outputs and corresponding trades are public - Autonomy: Each AI must generate alpha, size positions, time trades, and manage risk - Duration: Season 1 runs until November 3, 2025, at 5 p.m. EST Since the period is short (less than 20 days), luck plays a big role. But it would be interesting to keep a version running long-term and compare it to a simple BTC buy on day zero. #bitcoin #BTC #nostr

Some movements occur when the money supply increases: - The newly printed money goes into the hands of those closest to the printer; - With more money in circulation and no proportional increase in the supply of goods and services, the currency loses value; - Those holding money seek to preserve their purchasing power by allocating it into hard assets; - The value of these assets tends to rise (supply and demand). One of the charts shows exactly the relationship between Bitcoin’s boom-and-bust cycles and the money supply. Now, in October, Fed Chair Jerome Powell made statements suggesting that the end of QT (monetary tightening) may be near, which could pave the way for a new QE (monetary expansion). In a scenario of potential monetary expansion, gold has reaffirmed itself as a store of value, reaching record highs in recent weeks. Will Bitcoin follow the same path? #BTac #bitcoin #nostr

Would this be another 2025 Nobel for Bitcoin? An analogy helped me better understand the 2025 Nobel Prize in Economics: Imagine the beginning of humanity: each person fished their own fish daily. One day, someone had a revolutionary idea: decided to give up fishing and eating that day to dedicate their time and effort to another activity: building a fishing rod. Result? The next day, it was possible to fish more fish in less time, freeing up hours for other innovations: nets, better hooks, boats. That's how humanity evolved. Joel Mokyr, Philippe Aghion, and Peter Howitt won the 2025 Nobel for explaining this dynamic: sustained economic growth comes from innovation, which only happens when societies save resources today to invest in R&D tomorrow. The problem? Since 1971 (end of the gold standard), our economy does the opposite of what the laureates recommend: - Central banks print currencies that lose their purchasing power - Population is incentivized to consume instead of save - High time preference - "spend now, pay later" - Reduction of resources available for investment in innovation - Capital diverted to speculation instead of productive R&D Solution? A monetary system that: - Preserves purchasing power over time - Incentivizes real savings - Reduces time preference - Reallocates capital to productive innovation Remind you of something? Maybe Bitcoin? #bitcoin #btc #nostr

In 2017, Germany completed a repatriation operation of half the country's gold reserves, which lasted four years and cost 7.7 million euros. The operation aimed to repatriate all gold held in Paris and one-third of the reserves in the US, where it had been stored for many decades to prevent it from falling into the hands of the Soviet Union's communist regime during the Cold War. This cost of 7.7 million euros was purely operational and included: - Authentication verification; - Detailed weighing and laboratory testing; - Remelting of bars for international standardization required by banking records; - Transportation; - Insurance; It did not include the largest cost, which was precisely adapting the storage facility in Frankfurt for this reserve, estimated at 52 million euros. Now, imagine if there were an asset that could: - Be verified instantly instead of going through weighing, analysis, and laboratories; - Be transferred within 60 minutes, not four years; - Cost a few euros instead of tens of millions; #bitcoin #btc #nostr
