In the heart of Shenzhen’s bustling Huaqiangbei electronics market, the chaos that sent shockwaves through global cryptocurrency markets barely registered as a blip. While investors worldwide panicked as Bitcoin plunged nearly 30% in a single night, the merchants of Huaqiangbei remained unfazed—some even more energized.
On May 19, 2021, cryptocurrency markets experienced one of their most dramatic collapses: Bitcoin dropped from $34,000 to below $30,000 in under an hour; Ethereum tumbled over 40%; Dogecoin lost half its value. Nearly 480,000 traders were liquidated, wiping out over $5.9 billion in positions.
Yet just 19 hours later, inside the towering electronics complexes of Huaqiangbei, workers wheeled cartloads of graphics cards and mining rigs into elevators with urgency. Delivery couriers sprinted between floors. Demand for mining hardware hadn’t slowed—it had accelerated.

The Unshaken Heart of the Mining World
Huaqiangbei has long been known as “China’s Electronics Capital,” but in recent years, it's evolved into something far more specific: the world’s largest hub for cryptocurrency mining equipment. An estimated 90% of global mining hardware flows through its alleys and high-rises.
Despite the crash, prices for key components like the NVIDIA RTX 3080 remained stable—or even rose—reaching up to 16,000 RMB ($2,500) per unit, a nearly 300% increase from MSRP.
“Think prices will drop? Forget it,” said one shop owner who declined to give his name. “We can’t even get enough stock. If anything, prices might go higher tomorrow.”
This isn’t speculation—it’s supply chain reality. With miners still active worldwide, demand for high-performance GPUs and ASIC miners remains relentless. Each mining rig typically uses 6–8 graphics cards, creating massive downstream pressure on component availability.
Why Prices Won’t Drop—Even After a Market Crash
The logic in Huaqiangbei defies conventional market psychology. While most expect crypto price drops to reduce mining activity (and thus hardware demand), local vendors see things differently.
Mining isn’t about quick flips—it’s a long-term game of incremental gains. Miners earn coins slowly over time, not overnight.
Take Ethereum mining as an example: a single GPU might generate 0.001 ETH per day. It takes about 50 days to accumulate enough (0.05 ETH) to withdraw. At current rates, after electricity and hardware costs, annual profits may only reach $600–$800 per card—hardly a windfall.
But here's the twist: miners don’t sell immediately. They hold their coins, waiting for price rebounds. As one dual-role merchant-miner explained:
“We’re not traders panicking at every dip. We’re building stacks. When the market recovers, we cash out. That’s the strategy.”
So even when prices crash, miners keep running their rigs—they’re playing the long game.

Faith in the System: “It Will Bounce Back”
Merchants in Huaqiangbei aren’t just selling gear—they’re believers in the ecosystem. Many run mining operations themselves, giving them firsthand insight into market dynamics.
After the May 19 crash, Bitcoin rebounded within 30 hours, climbing back above $40,000 before dipping again. For these vendors, volatility is normal—expected, even.
“I’ve seen this movie before,” said Wang Qiang, a longtime GPU dealer. “In 2018, we had the ‘mining crash.’ Everyone said it was over. But look at us now.”
Their confidence stems from experience and data: as long as there are miners, there will be demand for hardware. And as long as cryptocurrencies maintain value—even if fluctuating—mining remains viable.
As one technician testing rigs put it:
“If you stop mining during a dip, you lose future gains. The real money comes when you mine through the storm and sell at the peak.”
The Real Game: Stockpiling and Scalping Components
Beyond retail sales, the real profits in Huaqiangbei come from component speculation.
Integrated circuits (ICs), memory chips, and motherboards have all surged in price due to mining demand and global supply constraints. A chip that cost 100 RMB last year now sells for over 1,000 RMB.
“Get the right model early? Double or triple your money in weeks,” said an IC supplier.
Industry insiders say average profits among top component dealers exceeded one million RMB ($155,000) in 2020 alone. In 2021, that benchmark became the entry ticket.
“If you haven’t made at least a million, you don’t even talk about it here,” joked one vendor.
But wealth isn’t measured in luxury cars or designer watches—it’s measured in storage space.
Successful merchants reinvest earnings into small warehouses (“xiaocang”) to hoard inventory. The cycle is simple:
- Buy low → Store → Sell high → Buy more storage → Repeat
It’s a self-reinforcing loop built on timing, trust in tech trends, and relentless optimism about digital assets.

Frequently Asked Questions
Q: Why didn’t the crypto crash affect mining hardware prices in Huaqiangbei?
A: Because mining is a long-term operation. Even during price dips, miners continue running rigs to accumulate coins for future sale. As long as mining persists, demand for GPUs and ASICs stays strong.
Q: Are people still making money from GPU mining in 2025?
A: Yes—but not through brute force alone. Profitability depends on low electricity costs, efficient hardware, and strategic holding of mined coins until market recovery.
Q: Is Huaqiangbei still the global center for mining equipment?
A: While regulatory shifts have impacted operations, Huaqiangbei remains a critical node in the global supply chain for mining components and custom-built rigs.
Q: Can individuals still profit from building mining rigs today?
A: Individual profitability has decreased due to competition and rising hardware costs. However, those with access to bulk components and cheap power can still achieve solid returns.
Q: What caused the massive increase in graphics card prices?
A: A combination of cryptocurrency mining demand, global semiconductor shortages, and supply chain disruptions drove prices up significantly—especially for high-hashrate models like RTX 3070/3080/3090.
Q: Will GPU prices ever return to normal?
A: Prices are expected to stabilize as newer technologies emerge (like specialized ASICs) and mining transitions away from consumer GPUs—though sudden crypto rallies could reignite demand temporarily.
Huaqiangbei’s resilience isn’t blind faith—it’s calculated confidence rooted in cycles they’ve lived through before. For these merchants, volatility isn’t risk; it’s rhythm. And as long as digital currencies exist, they’ll be ready—with warehouses full of chips and hands full of cash.
