"Unite all high-end graphics cards in the world!"
Over the past 30 days, millions of high-performance GPUs flooded Ethereum's (ETH) mining network.
Unprecedented Mining Profits Drive GPU Demand
As ETH prices surged, mining profitability reached historic highs. Ethereum's PoW algorithm, Ethash (Ethash Design Rationale), resists ASIC optimization, making high-end GPUs the only viable mining hardware. This triggered a rapid, large-scale mobilization of graphics cards, creating a staggering growth curve in ETH's total hashrate.
Between 2017-06-09 and 2017-07-09 (shaded area in chart below), ETH's network hashrate grew from 39.5TH/s to 64.8TH/s—a 25.3TH/s increase. Considering that an AMD RX 570/580 GPU typically delivers 22M-24Mh/s (up to 28Mh/s with BIOS optimization), conservative estimates suggest:
- Approximately 1 million GPUs joined the network during this period
- GPU prices skyrocketed from ¥1,500-2,000 to ¥3,000-3,500 due to shortages
- Total hardware value exceeded ¥2 billion (∼$300 million)

The ETH-BTC Market Cap Dance
During the first 10 days of this 30-day period, ETH maintained its ¥2,500 all-time high, causing its market dominance to nearly equal Bitcoin's:
| Date | BTC Dominance | ETH Dominance |
|---|---|---|
| 2017-06-17 | 38.44% | 31.93% |
Key observations:
- ETH's dominance grew from 5.32% to 31.93% in six weeks
- Bitcoin's market cap simultaneously doubled
- Post-June 17 correction saw BTC regain dominance while altcoins declined
The Crypto Landscape Shifts
This month-long market correction marked the end of crypto's spectacular first half in 2017. With Bitcoin's scaling solutions entering critical deployment phases, the industry stood poised for more transformation.
Blockchain enthusiasts anticipated:
- Technological breakthroughs in scaling solutions
- Evolving miner economics
- Regulatory developments worldwide

FAQ: The Great GPU Migration
Q: Why did ETH mining require so many GPUs?
A: Ethash's ASIC-resistant design made GPUs the most efficient mining hardware, creating massive demand during price surges.
Q: How did this affect GPU availability?
A: Shortages caused prices to double, impacting gamers and creating secondary markets for used mining cards.
Q: Will similar GPU rallies occur again?
A: With Ethereum's transition to Proof-of-Stake, large-scale GPU mining has ended—though other coins still utilize GPU-minable algorithms.
Q: What lessons did this event teach?
A: It demonstrated crypto's ability to disrupt traditional hardware markets and highlighted the volatility of mining economics.
Q: How did this impact cryptocurrency distribution?
A: The event temporarily reshaped market cap distributions before BTC regained dominance during subsequent corrections.
