By the end of 2025, Bitcoin mining difficulty just reached a record high of 148.26T, and industry insiders expect it may break through the 149T mark in January. This number looks intimidating, but the underlying logic is worth pondering.

Why is the difficulty still climbing? Simply put, it’s because global capital is truly betting real money on Bitcoin. Even after experiencing volatility in October, professional mining companies in North America, the Middle East, and Latin America are still accelerating the deployment of new machines. These players are not blindly throwing resources; they are well aware that the 2026 halving is coming. Locking in low-cost hash power now is essentially preempting future scarce returns.

From a network perspective, rising difficulty = increased security level = skyrocketing attack costs. Each difficulty adjustment makes attacking Bitcoin exponentially more expensive. This self-forming market defense system is a unique advantage that cannot be replicated by other assets, reinforcing BTC’s status as digital gold.

For participants, this stage is actually a period of strategic positioning. Small miners are gradually exiting, industry concentration is increasing, and the network will become more stable. Once the price breaks through a critical level, such high difficulty will instead create a natural ceiling for hash power—new hash power cannot enter, supply is locked, and demand is surging. This is a resonance opportunity.

149T is not an obstacle; it’s a proof of growth. The harder it is to mine, the more valuable the assets become.
