Bitcoin Mining: Difficulty Spikes, But Is It a Problem?

Bitcoin mining just got a whole lot harder.

Record Difficulty, Lower Hashrate

The difficulty of mining Bitcoin recently hit a record high of 135 trillion. This means it takes more computing power than ever to successfully mine a block. At the same time, the total computing power (hashrate) used by the network has dropped slightly from its peak, going from over 1 trillion hashes per second to 967 billion. This combination of increased difficulty and lower hashrate is squeezing the profit margins of miners, especially smaller ones. Smaller operations, with their tighter budgets for electricity, equipment, and maintenance, are feeling the pinch the most. Larger mining operations have more resources to absorb these increased costs.

The Rise of the Mining Giants?

This situation raises concerns about the centralization of Bitcoin mining. As costs rise, larger mining pools and companies are better equipped to survive, potentially leading to a less decentralized network.

Solo Miners Still in the Game

Despite the challenges, smaller, solo miners are still managing to win blocks and earn significant rewards. In July and August, several solo miners hit the jackpot, earning hundreds of thousands of dollars from a single block reward (which is currently around 3.125 BTC). While these wins are rare, they prove that it’s still possible for individuals to participate successfully in Bitcoin mining. However, the consistent earnings of larger mining pools still highlight the advantage of scale.

September’s Murky Market History

September has historically been a bit of a rollercoaster for Bitcoin. While 2023 and 2024 bucked the trend, the average return for September over the past twelve years is actually negative (-3.77%). This historical data is something to keep in mind, but it’s certainly not a guaranteed predictor of future performance.

What Does It All Mean?

In short, Bitcoin mining is getting tougher, and the network’s hashrate is slightly down. This creates financial pressure on miners, particularly smaller ones, and raises concerns about centralization. However, the fact that solo miners are still scoring big wins shows that the system isn’t completely dominated by large players. The coming months will be interesting to watch, as we see how the difficulty, hashrate, and Bitcoin’s price all interact.
