📰 What happened in mining last week EMCD Digest | September 14–20, 2026 ♦️ Bitcoin mining difficulty rose 4.16% to 132.76T The September 19 retarget lifted Bitcoin mining difficulty from 127.45T to 132.76T at block 967,680. Bitcoin was trading around $81,000 on September 20, helping offset part of the pressure that higher difficulty puts on dollar-denominated mining revenue. Less efficient fleets and miners paying higher power prices remain the most exposed as margins tighten.  ♦️ CoinShares: listed miners’ average cash cost ran 29% above Bitcoin’s quarter-end price The weighted average ex-tax cash cost to produce one BTC among listed miners was about $75,500 in Q2, against a $58,400 quarter-end price. Results diverged sharply: ABTC, Bitdeer, HIVE and IREN mined below their realised prices, CleanSpark and Riot sat near breakeven, while MARA’s $86,126 cash cost overshot its $70,315 realised revenue by roughly $15,800 per coin. Hashprice bottomed at $27.7 per PH/s/day in June. Core Scientific paid Block $41.9M to cancel about 15 EH/s of 3nm chip deliveries, and at least 35 EH/s is scheduled to leave the listed cohort. ♦️ Bitdeer mined 1,310 BTC in August but ended the month holding 61 Output rose 249% year over year from 375 BTC, with self-mining hashrate at 79.9 EH/s against 30.0 EH/s a year earlier — and CoinShares puts Bitdeer among the miners producing below their realised price in Q2. The treasury moved the other way: 61 BTC at month end versus 257 in July. Its AI cloud arm runs 4,328 GPUs at 92% utilisation for roughly $86M in annualised recurring revenue, plus a non-binding LOI for an initial 30 MW AI data center in Bhutan. ♦️ Ethiopia cut miners’ power supply by 77% The state utility reduced deliveries to 23% of contracted volumes after El Niño cut reservoir inflows by 20%, prioritising households and manufacturers. The cuts came in stages — 75%, then 50%, then 23%. Miners had supplied 35% of the utility’s revenue last fiscal year and consumed almost a thi

Mining payout schedule update ⛏️ Starting September 22, the mining payout window is changing as EMCD Mining Pool and Coinhold Wallet continue developing in their own directions.  What’s changing: Mining payouts move from 09:00–12:00 to 15:00–17:00 (UTC+3). What’s not: Everything else. Payouts stay daily, and no action is required from your side. New time, same flow.  🏭 Keep mining with EMCD 🔳 Community / Website / EMCD App / Twitter / Support

Happy World Teachers’ Day 🎉 Here’s to everyone who ever explained what a nonce is, helped set up a first ASIC, or answered a mining question in a group chat at 2am.   To celebrate, a quick pop quiz: five questions on things you deal with every day.  Peeking at your EMCD dashboard counts as open-book. Questions are right below. Good luck 👇 🔳 Community / Website / EMCD App / Twitter / Support

📰 What happened in mining last week EMCD Digest | September 28 – October 4, 2026 ♦️ September brought miners $1.12 billion, the best month since January  The October 3 retarget cut difficulty by just 0.03%, to 132.72T at block 969,696 — the smallest move of 2026, so the stronger month was not clawed back by the network. January remains the high at $1.15 billion. Across 2026 difficulty has seen eight increases and eleven decreases for a net decline of 11.96%. ♦️ Hashprice fell 3.8% while hashrate edged up  Hashprice slipped 3.8% to $39.87 per PH/s/day while the seven-day average hashrate rose 0.6% to 952 EH/s. At that level the gap between hardware generations decides the outcome: machines under 14 J/TH earn about $138 of gross revenue per MWh consumed, against roughly $52 for 25–38 J/TH models. ♦️ Gemini switched its Zcash node ahead of the move to 25-second blocks  On September 30 Gemini moved its Zcash infrastructure from Zebra to Zakura, which synced in just over six hours against nearly a day. The trigger is NU7, which cuts block spacing from 75 seconds to 25 and divides the reward per block by three so issuance stays on schedule. Fees change too: roughly 60% would be held out of circulation instead of paid to miners. November 5 is a target, not a confirmed date. ♦️ Public miners booked $1.1 billion in write-downs in the first half  Twelve public miners recorded about $1.1 billion in asset impairments and held-for-sale markdowns in the first half of 2026, per TheEnergyMag, with IREN and Core Scientific accounting for nearly 89% and IREN alone at roughly $695 million. Not all of it is the AI pivot: Core Scientific attributed its own impairment to deteriorating mining economics. Miner Weekly separately puts the hashrate taken offline at 75 EH/s — about $1.5 billion of hardware at an assumed $20 per TH. ♦️ Kazakhstan wants to run mining on associated petroleum gas  Kazakhstan is building a framework to run mining on associated petroleum gas now flared at the w
