According to the source, Bitdeer increased its pure holdings to 2,126.8 BTC, reflecting additional BTC retained on its balance sheet rather than distributed to market. source: X post dated Oct 19, 2025 referenced in the prompt. For traders, rising miner balances are commonly associated with lower immediate sell pressure and are tracked via metrics such as Miner Reserves and Miner to Exchange Flows. source: Glassnode Academy, explanations of Miner Net Position Change and Exchange Flows.

According to the source, Bitcoin (BTC) mining difficulty has reached a new all-time high. In Bitcoin, difficulty retargets every 2016 blocks and a higher difficulty indicates rising network hashrate (Bitcoin Core documentation). Higher difficulty lowers BTC-denominated revenue per unit of hashrate, compressing miner margins and reducing hashprice, a key revenue proxy for miners (Luxor Hashrate Index). Revenue stress can increase miner BTC sales and affect exchange flows and near-term liquidity, which traders track via miner reserves and miner-to-exchange flows (Coin Metrics). Profitability remains more resilient for low-cost power and latest‑gen ASIC fleets, while high‑cost operators face elevated shutdown risk when fees are subdued (Cambridge Centre for Alternative Finance CBECI; Luxor Hashrate Index equipment efficiency data). Near term, watch the next difficulty projection, hashprice, transaction fees, and miner reserve balances for potential impacts on BTC spot liquidity and volatility (Bitcoin Core documentation; Luxor Hashrate Index; Coin Metrics).
