Bitcoin's 11% Difficulty Drop: A Flow Test for Miners and Price

The Bitcoin network just underwent a severe flow shock. Mining difficulty fell 11.16% to 125.86 trillion at block 935,424, the largest single drop since China's 2021 ban. This followed a roughly 20% hashrate decline over the past month, triggered by a brutal price drop and winter storm curtailments. The immediate financial pressure is crushing: hashprice hit record lows near $33 per PH/day, far below the $40/PH/s/day threshold where miners decide to keep machines running.

This creates a dire cash squeeze. With the average all-in cost to mine one BTC at $84,300 and spot trading near $69,000, miners are operating at a massive loss. The flow of revenue has collapsed. In response, some are selling their own BTC to survive. Cango sold more than half its BTC recently to strengthen its balance sheet, a clear signal that operational cash flow cannot cover costs.

The situation is a classic liquidity crisis. Miners are caught between a collapsing revenue stream and fixed operational expenses. The difficulty drop offers a mechanical relief valve, but it does little to offset the fundamental pressure of a more than 45% price fall from its October peak. For now, the flow of BTC from miner wallets to the market is increasing, adding downward pressure on price.

Price Action: ETF Outflows vs. Mining Support

The price is under severe pressure from a flood of selling. Bitcoin has dropped some 26% over the past month, with recent lows near $60,000. A key source of that selling is spot Bitcoin ETFs, which saw net outflows of $641.9 million over the last 10 days. The average daily outflow was $64.2 million, but the flow spiked dramatically on February 4, with a single-day peak outflow of $763.0 million. This consistent, large-scale institutional selling is a major headwind.

Against this, the mining sector is showing a different kind of flow. After a brutal period, the network's hashrate has jumped more than 20% over the past two weeks and is recovering. This rebound signals that miners are plugging back in, a sign of resilience. Yet, this flow of returning hashrate is a double-edged sword. It will soon trigger a difficulty increase, which will squeeze miner profits again. For now, the flow of new BTC from mining is supporting network security, but it does not represent a direct price support mechanism.

The competing flows create a volatile setup. ETF outflows are a clear, ongoing drain on demand. Meanwhile, the mining recovery, while positive for network health, sets the stage for a future cost increase that could force more miners offline if price doesn't improve. The price must now navigate between these two powerful currents.

Catalysts and Risks: The Next Adjustment and Price Floor

The next major technical catalyst is imminent. The network's difficulty is set to increase by 10.70% to 139.33 trillion on February 20, 2026. This adjustment will follow a period of hashrate recovery, with the network's computing power jumping more than 20% over the past two weeks. The speed of that recovery is critical. If hashrate climbs rapidly before the adjustment, it will lock in a higher difficulty level, compressing miner margins even if the price stabilizes.

The immediate price floor is defined by miner economics. The average cost to mine one Bitcoin is cited at around $87,000, while spot trading is near $69,000. This creates a massive operational deficit. For miners to sustain operations, the price must hold above the $69,000 level to at least cover the cost of production. Any sustained drop below this point risks a new wave of miner distress sales, adding fresh selling pressure to the market.

The key risks are flow reversals and accelerated hashrate. Watch for a reversal in ETF outflows, which have been a major source of selling. A shift to inflows could provide a crucial demand offset. More immediately, monitor whether the hashrate recovery accelerates before the February 20 adjustment. A faster return of computing power means the difficulty increase will be steeper, squeezing profits for miners who are already operating at a loss. The setup is a race between price stability and the network's return to full strength.
