🗞 Crypto News: Weekly Overview It’s Monday, and we’re bringing you a digest of key events from the real crypto market! To keep you informed, we’ve decided to launch a weekly roundup of the most important developments. 🗓 So, what happened this week? ▪️Bitcoin rebounded after the release of U.S. inflation data, which slowed to 2.4%. At the time of publishing this digest, 1 BTC is trading at $68,513. ▪️The current average cost of mining BTC is estimated at $77–84K, while Bitcoin itself is trading around $65,000. Against this backdrop, network difficulty dropped by 15% – the largest decline in the past six months. Meanwhile, mining company Cango sold 4,451 BTC ($305 million) from its reserves to repay debt. ▪️JPMorgan estimated the current production cost of BTC at $77K and maintained its long-term price target of $266K. ▪️CoinShares assessed the actual scale of the so-called quantum threat at just 10,200 BTC. Stay tuned – we’ll be back next week with more updates. ❤️ ECOSMiningGamebot

🟠 What structure links transactions inside a block? 👉 Merkle tree It’s a structure that links all transactions inside a block into a single hash tree! ✅ Thanks to it, the network can quickly verify data integrity and ensure nothing has been altered.

👾 What is the name of Bitcoin’s block validation rule requiring correct difficulty? 👉 Target check This rule verifies that a block’s hash meets the network’s current difficulty target. If the hash is above the allowed threshold, the block is rejected.

🟠Is Bitcoin decentralized? Oh no, you’re in the right place! This is simply the first post from our knowledge library, because we want you to become a true crypto guru. And today, we’re answering a key question: is Bitcoin decentralized? The short answer is yes. 🤓 ☝️ Bitcoin has no single owner or central authority. Its network is made up of thousands of independent nodes around the world. Anyone can run a node, become a miner, and verify transactions using a blockchain explorer. In the Bitcoin network, decisions are made through consensus. If a block or transaction breaks the rules, the network simply rejects it. 👏 Of course, Bitcoin isn’t perfect – but today, it remains one of the most decentralized systems in the world. Thanks to decentralization, no one can: ▪️Issue extra BTC ▪️Reverse transactions ▪️Change the network rules on their own 🫶 If someone tries, the network simply says “no.” This is exactly what gives Bitcoin something traditional money doesn’t have: censorship resistance and independence from banks. ❤️ ECOSMiningGamebot

🔎 What is the value of the Coinbase maturity requirement? 👉 100 blocks The reward from a coinbase transaction cannot be spent immediately. 🟠 BTC from a coinbase transaction becomes spendable only after the block receives at least 100 confirmations on the blockchain.

🫶 Yes, rewards here take time – but in our game, you can get XP right now!

🔎 What technique reduces blockchain bloat? 👉 Pruning It’s a method where a node removes old and unnecessary blockchain data, keeping only what’s needed to verify new blocks. ⚡️Less data – easier storage.

👾 What is the term for the fee paid per byte? 👉 Sats per byte ▪️ It’s a unit used to measure transaction fees. Satoshis are the smallest fraction of Bitcoin – 1 BTC = 100,000,000 sats. ▪️ The fee is calculated not per transaction as a whole, but per byte of data the transaction takes up in a block.

🗓 Crypto News: Weekly Highlights We’re sure you’re fully up to date with everything happening in our game – but what about the biggest events in the real crypto market? To keep you in the loop, we’ve decided to put together a weekly digest for you. And this is the very first edition! 🤓 So, what interesting things happened this week? ▪️ Bitcoin experienced its longest downturn in 7 years, tested support at the $60,000 level, and triggered liquidations worth billions of dollars. ▪️ Bitcoin miners massively shut down equipment amid record losses. Hashprice (revenue per unit of computing power) dropped to $0.03 per terahash. For comparison, in 2017 this figure was around $3.5. ▪️Major South Korean crypto exchange Bithumb reported an internal error during bonus payouts: instead of 2,000 Korean won (about $1.5), some accounts were mistakenly credited with 2,000 BTC. ❤️ ECOSMiningGamebot

🫶 What is the outcome of mining a block with invalid transactions? 👉 Block rejection If a block contains invalid transactions, the network simply rejects it – no reward and wasted effort. Bitcoin plays by strict rules. 👏 Our game has its own rules too! Jump into the game right now and grab your XP. Combo Code: 454454 ❤️ ECOSMiningGamebot

👾 What is the minimum number of peers a node connects to by default? 👉 8 peers By default, a node connects to at least 8 other peers to receive data, validate blocks, and stay part of the network. Fewer connections increase the risk of isolation.

🧐 What is the name of Bitcoin’s difficulty target format? 👉 Compact encoding (nBits) nBits defines the range of acceptable hashes and, as a result, affects the mining difficulty of new blocks. The lower the target value, the less likely a random hash is to fall below it — and the harder mining becomes.
