Bitcoin mining difficulty hits all-time high

Bitcoin’s (BTC) mining difficulty surged to an all-time high of 127.6 trillion this week, underscoring the network’s growing computational power. However, a downward adjustment is expected on August 9, with projections pointing to a roughly 3% decrease, bringing difficulty down to 123.7 trillion, according to data from CoinWarz.

Currently, the average block time sits at approximately 10 minutes and 20 seconds, slightly above the protocol’s 10-minute target. Difficulty adjustments help bring this time back in line by responding to changes in the total computing power, or hashrate, dedicated to mining.

CryptoQuant data shows that mining difficulty declined throughout June, hitting a low of 116.9 trillion in early July. However, the trend reversed in late July, resuming the long-term upward trajectory tied to increased miner participation.

Bitcoin’s soaring stock-to-flow ratio signals rising scarcity

Bitcoin mining difficulty measures how hard it is for miners to find a valid hash for the next block. It adjusts every 2,016 blocks—roughly every two weeks—to maintain a steady block time of around 10 minutes, regardless of changes in network hashrate.

When difficulty rises, mining becomes more expensive and less profitable unless BTC’s price also climbs. A drop in difficulty, on the other hand, offers miners short-term relief by making rewards easier to earn with the same equipment.

Mining difficulty and network hashrate are critical not just for security but also for maintaining Bitcoin’s stock-to-flow ratio—a key measure of scarcity. This ratio compares the existing supply of an asset to the rate of new supply entering the market.

A high stock-to-flow ratio indicates that new production has a minimal impact on the overall supply, helping preserve price stability. BTC’s stock-to-flow ratio is currently higher than gold’s, making it “twice as scarce,” according to PlanB, the analyst who developed the stock-to-flow pricing model. With about 94% of its capped 21 million BTC already mined, Bitcoin boasts an estimated stock-to-flow ratio of 120, compared to gold’s 60.

Silver, by contrast, was historically demonetized partly due to its much lower stock-to-flow ratio. When silver prices rise, more supply floods the market, pushing prices back down—a phenomenon Bitcoin is designed to resist.

Bitcoin’s self-adjusting difficulty keeps block production steady and supply predictable

Bitcoin’s protocol includes automatic difficulty adjustments roughly every two weeks. When more miners join the network and the hashrate rises, mining becomes harder, slowing down block production until the difficulty adjusts. The opposite happens when the hashrate drops—the difficulty is reduced to keep the average block interval close to 10 minutes.

This mechanism ensures that BTC’s issuance remains predictable and avoids sudden supply shocks that could trigger market volatility. By adjusting the difficulty of matching available computing resources, the protocol maintains the assets’ inelasticity to production—one of the key attributes underpinning Bitcoin’s value proposition as “digital gold.”

Bitcoin slips as Kimchi premium returns

As mining difficulty prepares for a potential drop, Bitcoin’s price remains under pressure. Bitcoin slipped 3%, hitting an intraday low of $112,680, then bounced back. By 7:30 pm ET, BTC was at $113,375. South Korea was once again at a premium—$113,987, 0.84% higher than the global average—and the Kimchi premium was back after a nearly month-long absence.

This premium often means rising domestic demand or region-specific regulatory issues. Despite the pullback, Bitcoin has a 61.4% market share.
