👾 What is the name of the attack where miners censor transactions? The attack where miners intentionally censor transactions is called a censorship attack. In this scenario, miners simply exclude certain transactions from blocks, which can be used to block payments, influence the market, or restrict users’ access to the network. ⚠️ There are almost no recorded cases of mass censorship of transactions in Bitcoin by miners. The network is designed so that miners compete for rewards, and the economic incentive usually encourages them to include as many transactions with high fees as possible. ☝️ Nevertheless, such an attack is theoretically possible! Understanding these attacks is important for evaluating Bitcoin’s resistance to censorship and for developing mechanisms that make the network more decentralized and secure.

🟠 What is the soft cap of Bitcoin block weight after SegWit? After the implementation of SegWit (Segregated Witness), the block weight limit was set to 4 million weight units (MB). SegWit separates transaction signatures from the main block content, allowing more transactions per block without breaking protocol limits. This innovation increased network throughput and enabled the development of scalable solutions like the Lightning Network. Combo Code: 807044 Question of the Day: 4 MB ❤️ ECOSMiningGamebot

🫶 Which country declared Bitcoin legal tender in 2021? In 2021, El Salvador became the first country in the world to declare Bitcoin legal tender. The government took this step to promote financial inclusion, facilitate remittances from abroad, and attract investment to the economy. Since then, El Salvador has continued to actively accumulate bitcoins, using them as a strategic asset to strengthen the economy and diversify national reserves. ☝️ This policy has helped the country attract tourists and investors, create jobs, and develop innovative financial technologies. Recognizing Bitcoin as an official currency marked a significant milestone in the history of cryptocurrencies. Combo Code: 281798 Question of the Day: El Salvador ❤️ ECOSMiningGamebot

🟠 What pseudonymous email domain did Satoshi use? Satoshi Nakamoto used an email at gmx.com. GMX is a popular German email service that allows users to create free addresses and maintain anonymity. It was through an address on this domain that Satoshi communicated on forums and mailing lists, discussing the details of the Bitcoin whitepaper and sharing technical materials with early community members. 1️⃣ Using a pseudonymous address helped Satoshi remain anonymous, allowing the project to develop without being tied to a single individual and focus on the technology and the idea of a decentralized currency. Combo Code: 395833 Question of the Day: gmx.com ❤️ ECOSMiningGamebot

🤑 What year did Hal Finney receive the first Bitcoin transaction? Hal Finney received the first Bitcoin transaction in 2009. He was a renowned cryptographer and one of the earliest Bitcoin adopters, actively testing and supporting the new digital currency. 1️⃣ The first transaction marked a milestone, showing that Bitcoin works in the real world, not just on paper. ☝️This moment demonstrates the beginning of Bitcoin’s practical use. Hal Finney’s involvement, as a respected figure, gave credibility to the project and encouraged the growth of the cryptocurrency community. Combo Code: 324219 Question of the Day: 2009 ❤️ ECOSMiningGamebot

🫶 What is stored inside a Bitcoin block header to link blocks together? Each Bitcoin block header stores the hash of the previous block. This is a key element that ensures the integrity of the blockchain: every new block “points” to the previous one, forming an unbroken chain. If someone tries to alter data in an old block, the hashes of all subsequent blocks will become invalid, and the network will detect it immediately. 🟠 Why does it matter? The hashing mechanism and the link through the previous hash make the blockchain tamper-resistant and secure. Thanks to this, the blockchain remains decentralized and reliable even without a central authority. Combo Code: 281948 Question of the Day: Previous block hash ❤️ ECOSMiningGamebot

🫶 What’s the mining reward expected after the 2028 halving? Currently, the block reward in the Bitcoin network is 3.125 BTC. After the next halving, it will be reduced by half to 1.5625 BTC. According to projections, the halving is expected on April 2028, at block height 1,050,000. 👾 What does this mean? Halving is a mechanism in the Bitcoin protocol that halves miner rewards approximately every 4 years. It is a key tool for controlling Bitcoin’s issuance and maintaining its scarcity, which affects its long-term value. 📈 Why does it matter? With reduced rewards, mining blocks become less profitable, encouraging the development of more efficient hardware and strategies, while also influencing Bitcoin’s market price. Combo Code: 528444 Question of the Day: 1.5625 BTC ❤️ ECOSMiningGamebot

👾 What is the name of the difficulty retarget formula? Mining difficulty measures how hard it is to find a new block in the network. The goal of the algorithm is to keep blocks appearing roughly every 10 minutes. If miners become stronger (network hashrate increases), blocks are found faster. If miners become weaker, blocks take longer. To maintain the ~10-minute target, the network adjusts the difficulty. 🤔 Why does it matter? Without difficulty adjustment, blocks could be mined too quickly or too slowly, disrupting the balance and stability of the network. 👾 How Kimoto Gravity Well works Kimoto Gravity Well (KGW) is a method designed to respond more flexibly and quickly to changes in network hashrate: ▪️ Adjustment occurs every block, not every 2016 blocks. ▪️ The algorithm considers the timestamps and difficulty of the last several blocks (e.g., 24–100). ▪️ It provides a faster response to sudden changes in network power (e.g., when miners leave or join the network). ▪️ KGW uses weighted averaging to prevent extreme swings while adapting faster than Bitcoin’s standard formula. As a result, block times remain stable, and the risk of attacks – where a single miner could significantly slow down the network – is reduced. Combo Code: 469216 Question of the Day: Kimoto Gravity Well (trivia, though Bitcoin uses standard adjustment) ❤️ ECOSMiningGamebot

🟠 What company holds the most Bitcoin as a public firm? Today, the record belongs to MicroStrategy – a publicly traded company that actively invests in Bitcoin and has made it a key part of its strategy. In 2020, MicroStrategy was one of the first companies to adopt a BTC accumulation strategy, based on the belief in Bitcoin as the best deflationary asset. According to publicly available data, MicroStrategy now holds over 640,030 bitcoins. 👌Why does it matter? MicroStrategy has shown the world that institutional players can view cryptocurrency not just as a speculative asset, but also as a store of value. Through its active Bitcoin acquisition strategy, the company has inspired other corporations and investors to consider digital assets as a long-term investment tool. Combo Code: 704435 Question of the Day: MicroStrategy ❤️ ECOSMiningGamebot

🟠 Which Bitcoin fork happened in August 2017? In August 2017, the cryptocurrency world saw the birth of Bitcoin Cash – one of the most well-known and controversial Bitcoin forks. 👾 What is Bitcoin Cash? Bitcoin Cash split from the original Bitcoin to address network scalability issues and speed up transaction processing. Key changes included: 🔸 larger block size, 🔸 faster transactions, 🔸 lower transaction fees. 👾 However, Bitcoin Cash is not so straightforward Bitcoin Cash sparked heated debates in the community: many investors and users faced losses due to extreme price volatility, the network split, and unpredictable consequences of the fork. For some, it was an opportunity to profit; for others, it led to significant financial losses. Combo Code: 304261 Question of the Day: Bitcoin Cash ❤️ ECOSMiningGamebot

👏 What is the first Bitcoin improvement proposal for SegWit? SegWit became one of the most important upgrades in Bitcoin’s history, and it all began with BIP141 – the proposal that first introduced the mechanism of separating signature data (witness data) from the main part of a transaction. 🤖 What is BIP141? Published in 2015, BIP141 defined the technical structure of Segregated Witness and described how the upgrade should function at the protocol level. Its goals were simple, yet revolutionary: – reduce transaction weight, – increase network throughput, – eliminate transaction malleability, – enable second-layer solutions such as the Lightning Network. 🟠 Why does it matter? SegWit became a foundation for scalability, security, and modern Bitcoin development. Without BIP141, there would be no Lightning Network, no advanced wallets, and not many of the tools the ecosystem relies on today. BIP141 is the point where the era of the “new” Bitcoin begins.

🫶 Which fork introduced SegWit2x proposal? SegWit2x is one of the most controversial initiatives in Bitcoin’s history. It emerged from the New York Agreement – a deal struck between major miners, companies, and services that attempted to solve Bitcoin’s scaling debate from the top down, without broad community participation. 👾 What was SegWit2x? The idea was to activate SegWit, and then raise the block size to 2 MB. On paper, it looked simple. In reality, it threatened Bitcoin’s decentralization. 👾 Why did it spark so much conflict? – The New York Agreement was signed behind closed doors. – Independent nodes and community participants didn’t support it. – It created the risk of a “forced” change to consensus rules. – The community believed Bitcoin upgrades must be made openly and with wide consensus. 🟠 In the end, the SegWit2x fork was canceled before launch – it couldn’t withstand community pressure. The New York Agreement became a reminder that any attempt to manage Bitcoin in a corporate, centralized manner is destined to fail. New York Agreement is the correct answer – and an important lesson: Bitcoin evolves bottom-up, not top-down. Combo Code: 254294 Question of the Day: New York Agreement ❤️ ECOSMiningGamebot

👾 What is the main difference between Bitcoin and Bitcoin Cash? Bitcoin and Bitcoin Cash are often confused because they share the same origin, but there is one key technical difference that shaped the future of both networks: block size. In 2017, the Bitcoin community faced a major debate about scalability. Some participants believed block size should be increased to speed up transactions and reduce fees. Others argued that doing so would threaten decentralization and network security. What happened? The disagreement led to a hard fork – this is how Bitcoin Cash was created. The main difference? Block size. 🔸 Bitcoin kept the 1 MB block limit (with later optimizations through SegWit and Lightning). 🔸 Bitcoin Cash increased block size to 8 MB and later even higher, attempting to scale the network “on-chain.” 🟠 Why does it matter? ▪️Bigger isn’t always better. Larger blocks require more powerful hardware, reduce node accessibility, and undermine decentralization – the core principle Bitcoin was built upon. ▪️Bitcoin chose the path of second-layer scaling (L2) and protocol optimization. ▪️Bitcoin Cash chose the path of simply increasing on-chain capacity. 🗓 Today, Bitcoin remains the leading asset of the crypto industry and the global standard. The 2017 debate showed that preserving decentralization matters more than short-term convenience. Combo Code: 263845 Question of the Day: Block size ❤️ ECOSMiningGamebot

🟠 What message did Satoshi include in the Genesis Block? We’re continuing the topic we started yesterday – the Genesis Block deserves much more than a single question. It’s the foundation of Bitcoin, the point where all crypto history begins. 👾 What message did Satoshi leave? In the very first block of the Bitcoin network – the Genesis Block – Satoshi Nakamoto embedded a headline from The Times: “Chancellor on brink of second bailout for banks” It wasn’t just a headline. It was a manifesto. 🫶 Why does it matter? This phrase refers to the 2008 financial crisis and reveals the reason Bitcoin was created: – distrust in the banking system, – frustration with centralized control, – the need for an alternative. Satoshi literally encoded the meaning of the entire idea into the first block: Bitcoin is a response to the failures of the old financial world. The Genesis Block is not just a historical artifact. It’s a message – one that remains relevant today. Combo Code: 121601 Question of the Day: “Chancellor on brink of second bailout for banks” ❤️ ECOSMiningGamebot

🟠 What is the nickname of block 0? The correct answer is Genesis Block – the very first block in the Bitcoin blockchain, created by Satoshi Nakamoto on January 3, 2009. It carries symbolic weight! The word “genesis” literally means “origin” – and this block indeed marks the birth of an entirely new financial system. 👏 Why it matters The Genesis Block is unique because: – Its reward (50 BTC) can never be spent. – It established Bitcoin’s monetary system. – It symbolizes the beginning of decentralized finance. 👾 Every blockchain has a first block. Bitcoin has a legend. Combo Code: 521275 Question of the Day: Genesis Block ❤️ ECOSMiningGamebot

👾 Who is known as the “Bitcoin Jesus”? The nickname “Bitcoin Jesus” is often associated with Roger Ver – one of the earliest and most vocal promoters of Bitcoin in the early 2010s. But an important point: we wouldn’t call him that. And not just because the nickname is loud – there are many controversies surrounding him. Why was he called “Bitcoin Jesus”? In the early days, Roger Ver: – actively promoted Bitcoin when almost no one had heard of it yet, – invested in the first crypto companies, – spoke at conferences, explaining the benefits of decentralized money. Because of this, the media labeled him “Bitcoin Jesus” – the person who “brought Bitcoin to the masses.” 👏 But the story isn’t that simple Roger Ver is one of the most controversial figures in crypto history. Here’s why: 🔸 Support for radical protocol changes He strongly pushed for increasing Bitcoin’s maximum block size – something the community viewed as a threat to decentralization and network security. This conflict became one of the reasons Bitcoin Cash was born. 🔸 Legal troubles Over the years, Ver faced accusations including tax fraud and various financial violations. 🔸 Community division His stance on Bitcoin vs. Bitcoin Cash split parts of the ecosystem, and debates around him continue to this day. 🤖 What’s important to understand? Yes, Roger Ver played a role in Bitcoin’s early popularization. But idealizing him is not the right approach – many of his actions were not beneficial for the network, and some even went against Bitcoin’s core principles. Combo Code: 179060 Question of the Day: Roger Ver ❤️ ECOSMiningGamebot

🤖 Which major upgrade introduced Pay-to-Script-Hash (P2SH)? 🤑 BIP16 (Pay-to-Script-Hash, P2SH) is a Bitcoin protocol proposal that introduces a new transaction type – P2SH. This upgrade became a significant milestone in the history of digital gold and the first major protocol improvement after Satoshi Nakamoto’s departure. 🟠Before P2SH, complex scripts were placed on the sender’s side. This meant: – expensive transactions, – compatibility issues, – lack of flexibility for developers. 🗓 What did BIP16 change? When the BIP16 upgrade activated in 2012, it: – made multisig wallets practical, – enabled escrow systems, – improved storage security, – simplified the development of complex smart scripts, – made transactions more flexible and resilient. Without BIP16, there would be no modern custodial schemes or most of the infrastructure solutions used today by exchanges and services. 🪙 P2SH became a foundational layer upon which today’s Bitcoin ecosystem was built. Combo Code: 226565 Question of the Day: BIP16

👾 What’s the term for the smallest amount of Bitcoin locked in the network forever due to lost keys? In Bitcoin, every satoshi matters – but not all of them are accessible. Some amounts of BTC will never move again. They’re stuck in wallets whose private keys are lost forever. These amounts have a name: Lost coins. 📈 But why do they matter? What are “lost coins”? Lost coins are bitcoins that technically still exist on the blockchain, but are mathematically impossible to spend because the private keys are gone. This happens when someone: – loses access to a hardware wallet – throws away a hard drive – forgets a seed phrase – or accidentally sends BTC to an invalid address Even a single lost satoshi becomes permanently removed from circulation – forever. 🤑 Why is this important for Bitcoin’s economy? Effective supply decreases. Bitcoin has a hard limit of 21 million coins – but the real spendable supply is lower. Millions of BTC are estimated to be lost forever. Scarcity increases naturally. Every lost sat tightens supply even more – making Bitcoin rarer over time and reinforcing its digital-gold properties. The network stays fair and predictable. Lost coins don’t break Bitcoin. They simply remain frozen in the ledger as permanent reminders of the importance of key security. 🫶 Interesting fact According to various estimates, the number of coins lost forever ranges from 1.5 to 4 million BTC. That’s a huge amount – and in the Bitcoin system, every satoshi counts! Combo Code: 267911 Question of the Day: Lost coins ❤ ECOSMiningGamebot
