On September 4, 2019, Bitcoin is trading at $10,594 with a market capitalization of approximately $189.8 billion, and the network’s security infrastructure has never been stronger. The hashrate — the total computational power dedicated to mining Bitcoin — is surging toward record territory, reinforcing the blockchain against attacks and signaling deep institutional confidence in the world’s first cryptocurrency.
TL;DR
- Bitcoin hashrate approaching 80 EH/s, with projections to reach 100 EH/s by late 2019
- BTC dominance at 70%, highest since March 2017, reflecting mining concentration on the flagship cryptocurrency
- Network difficulty climbing as next-generation ASIC miners come online globally
- Mining industry recovering strongly from crypto winter, with major operations expanding
- Growing institutional interest from traditional finance validates Bitcoin’s long-term security thesis
The Hashrate Security Shield
Bitcoin’s hashrate serves as the backbone of its security model. Every exahash per second represents an enormous amount of computational work that an attacker would need to overcome in order to manipulate transactions. As of September 2019, the network is processing approximately 80 quintillion hashes per second — a figure that has grown roughly 40% since the beginning of the year alone.
This growth has been driven by several factors. First, the recovery in Bitcoin’s price from below $4,000 in late 2018 to over $10,500 by September 2019 has restored profitability for miners operating efficient hardware. Second, the deployment of next-generation mining equipment — including the Bitmain Antminer S17 series and competitors from MicroBT and Canaan — has dramatically improved hash-per-watt efficiency, making it economically viable to deploy more machines.
The geographic distribution of mining has also continued to evolve. While China still commands a significant share of global hashrate, regions including North America, Central Asia, and Northern Europe have attracted growing mining operations, drawn by cheap renewable energy sources and increasingly favorable regulatory environments.
Mining Difficulty Adjustments Keep Rhythm
Bitcoin’s built-in difficulty adjustment mechanism has been working as designed throughout 2019. Every 2,016 blocks — approximately every two weeks — the network recalibrates how difficult it is to find a valid block. As more hashpower comes online, the difficulty increases, maintaining the target 10-minute block time.
Throughout 2019, the trend has been overwhelmingly upward, with only occasional downward adjustments when temporary hashrate fluctuations occurred. For example, the hashrate on September 16, 2019, would hit 101.23 EH/s before a temporary dip to 88.96 EH/s the following day — a 12% swing that illustrates the volatility inherent in mining operations. Despite these short-term fluctuations, the overall trajectory has been decisively bullish for network security.
Institutional Mining and the Road to Halving
The institutionalization of Bitcoin mining is accelerating. Major mining operations have been raising capital, securing cheap energy contracts, and building industrial-scale facilities designed to operate for years. This professionalization of mining is a far cry from the early days when hobbyists could mine Bitcoin on their laptops.
The upcoming halving in May 2020, which will reduce the block reward from 12.5 BTC to 6.25 BTC, is adding urgency to the expansion race. Miners want to accumulate as much hashrate as possible before the revenue cut, knowing that the subsequent price appreciation — if historical patterns hold — will more than compensate for the reduced block reward.
Companies like Copper Technologies are now holding between $100 million and $500 million in crypto assets for institutional clients, and firms like JST Capital — founded by veterans from UBS, Royal Bank of Scotland, and Bank of America — are providing sophisticated financial tools to institutional crypto investors. This institutional infrastructure buildup validates the thesis that Bitcoin mining is becoming a mature, professional industry.
Bakkt and the Institutional Gateway
The imminent launch of Bakkt, a subsidiary of the Intercontinental Exchange (ICE) — the parent company of the New York Stock Exchange — represents another milestone for Bitcoin’s institutional credibility. Bakkt is preparing to offer physically settled Bitcoin futures, providing regulated exposure to BTC for institutional investors who have been sitting on the sidelines.
For miners, the introduction of regulated futures markets creates new hedging opportunities. Miners can lock in future prices for their BTC production, reducing the revenue volatility that has historically made mining a boom-and-bust business. This financialization of Bitcoin mining is expected to attract even more institutional capital to the sector.
Why This Matters
Network security is Bitcoin’s most fundamental value proposition. Without a robust, decentralized mining ecosystem, the entire system would be vulnerable to attack and manipulation. The hashrate surge of 2019 — up 40% year-to-date and approaching 100 EH/s — demonstrates that Bitcoin’s security is strengthening even as the market recovers from one of its deepest downturns. For investors, developers, and businesses building on Bitcoin, this growing hashpower provides the foundation of trust that makes the entire ecosystem viable. The stronger the network, the more valuable Bitcoin becomes as a store of value and medium of exchange.
