Bitcoin mining is experiencing a remarkable resurgence in 2019, with the network hashrate surging nearly 40% since the start of the year and approaching all-time highs. As of September 4, 2019, Bitcoin is trading at $10,594, and the mining ecosystem is showing clear signs of renewed confidence — a stark contrast to the depths of the crypto winter that gripped the market throughout 2018.
TL;DR
- Bitcoin hashrate has surged approximately 40% since January 2019, nearing all-time highs
- BTC price has rallied over $1,200 in the past five days, reaching above $10,600
- Bitcoin dominance has hit 70% for the first time since March 2017
- Mining difficulty continues climbing as more hashpower comes online
- The network is on track to hit 100 EH/s before the end of the year
Hashrate Surge Signals Miner Confidence
The Bitcoin network hashrate has been on a relentless upward trajectory throughout 2019. By early September, estimates placed the hashrate at approximately 80 exahashes per second (EH/s), with analysts projecting it could reach 100 EH/s before year-end. This represents a dramatic recovery from the post-bubble lows of late 2018, when many smaller miners were forced to shut down unprofitable operations.
The surge in computational power dedicated to Bitcoin mining reflects a fundamental shift in miner sentiment. Despite the volatility that saw BTC plunge from nearly $20,000 in December 2017 to below $4,000 by late 2018, the subsequent recovery to above $10,000 has made mining profitable again for operators with efficient hardware — particularly those running next-generation ASIC miners like Bitmain’s Antminer S17 and MicroBT’s Whatsminer M20S.
Price Rally Fuels Mining Economics
The economics of Bitcoin mining are directly tied to the cryptocurrency’s market price, and the 2019 rally has been a game-changer. Over the past 90 days, Bitcoin has risen over 36%, making it the best-performing large-cap digital asset during that period. In just the past five days alone, BTC has surged more than $1,200, briefly crossing $10,600 on September 4.
This price appreciation has been partially attributed to macroeconomic factors, including the weakening of the Chinese yuan against the US dollar, which has driven increased interest in Bitcoin as a potential hedge. As fiat currencies in emerging markets face pressure, Bitcoin’s appeal as a borderless store of value has strengthened — and miners are positioning themselves accordingly.
Dominance and Difficulty on the Rise
Bitcoin’s growing mining power is mirrored by its increasing market dominance, which recently hit 70% for the first time since March 2017. This metric reflects Bitcoin’s outperformance relative to altcoins, many of which have struggled significantly. Ethereum, the second-largest cryptocurrency by market cap, has dropped nearly 50% from its 2019 peak of $349, currently trading around $176.
The rising hashrate has also triggered a series of mining difficulty adjustments upward. Bitcoin’s protocol automatically recalibrates difficulty every 2,016 blocks — roughly every two weeks — to maintain a 10-minute average block time. As more miners join the network and contribute hashpower, the difficulty increases, making it harder to mine each block but simultaneously making the network more secure against potential 51% attacks.
Looking Ahead: The 2020 Halving
The current mining boom is taking place against the backdrop of the upcoming Bitcoin block reward halving, expected in May 2020. When this event occurs, the reward for mining a block will be cut from 12.5 BTC to 6.25 BTC. Historically, halvings have been followed by significant bull runs, and many miners are expanding operations in anticipation of this cycle repeating.
However, the halving will also squeeze margins for less efficient miners. Those running older hardware or operating in regions with high electricity costs may find themselves unprofitable after the reward reduction. This dynamic is expected to accelerate the ongoing trend of mining consolidation, with larger operations gaining an ever-greater share of the network’s total hashrate.
Why This Matters
The hashrate surge to near-record levels is one of the strongest fundamental signals in Bitcoin. Unlike price, which can be influenced by speculation and market manipulation, hashrate represents real capital expenditure — miners purchasing hardware, securing facilities, and consuming electricity. When hashrate rises, it means miners are making long-term bets on Bitcoin’s future value. The 40% increase in 2019 shows that the mining industry has recovered from the crypto winter and is positioning itself for what many believe will be another major bull cycle driven by the 2020 halving.
