The Profit Surge: Real Returns from Real Hardware
For miners like Li Wen, the investment has paid off handsomely. In mid-2024, he spent 70,000 yuan ($10,000) on 10 secondhand WhatsMiner M20S units, each delivering 65 terahashes per second (TH/s). These machines generate roughly one Bitcoin annually under current network conditions—now worth over $300,000.
But it’s not just the mined coins that are valuable. The resale value of the hardware itself has skyrocketed. "I'm earning on both ends—the coins I mine and the appreciation of the machines," Li Wen says proudly.
Peter, another seasoned miner, made an even larger bet back in 2019. With a $300,000 investment in 200 M20S miners, he's since mined over 50 Bitcoins—worth more than $16 million at current valuations. After covering electricity costs averaging $22,000 monthly, his net profit exceeds $10 million. He plans to hold long-term, convinced that Bitcoin’s price will continue its upward trajectory.
This optimism fuels a broader trend: mining is no longer a niche hobby but a serious financial strategy embraced by individuals and institutional players alike.
Market Chaos: Mining Equipment in High Demand, Low Supply
Today’s mining market resembles a seller’s paradise. New and used ASIC miners are nearly impossible to find. What was once a modest retail scene in Beijing with accessible storefronts now lies dormant—most shops have closed due to inventory shortages.
"Most buyers now go straight to manufacturers or join group purchases," Li Wen explains. "Even pre-release units get snapped up before leaving the factory."
Top manufacturers like Bitmain (Antminer) and Canaan (Avalon) report sold-out product lines. Antminer S19 models, priced around $2,900 at launch, now sell for over $7,300 in secondary markets—a 150%+ increase. Futures contracts have seen even steeper climbs; the same model went from $1,900 in early 2024 to over $7,700 by early 2025.
Orders are growing in scale too. While group buys used to involve 50–200 units, recent deals exceed 1,000 machines—with one order reaching 5,000 units.
Industry consolidation follows this boom. Cipher Mining, a subsidiary of Bitfury Group, is set to go public via SPAC merger with GWAC Holdings, targeting a $2 billion valuation on Nasdaq. If successful, it could become North America’s leading Bitcoin mining operator.
Despite the trauma of the March 2024 "Black Thursday" crash—when Bitcoin dropped 25% overnight and mining profitability collapsed—miners today remain undeterred. Used miners that once sold for scraps now fetch up to $2,900 each.
"Back then, people were dumping machines like trash," Li Wen recalls. "Now? Everyone’s rushing back in."
The reason is simple: although miner prices have doubled or tripled, Bitcoin’s price has increased over 4.5x in the same period. Payback periods have shrunk from 12 months to under 8 months for many setups.
Ethereum’s GPU Gold Rush: From Desktops to Dismantled Laptops
While Bitcoin mining relies on specialized ASICs, Ethereum mining runs on GPUs—graphics processing units primarily designed for gaming. This overlap has triggered a global shortage of high-performance graphics cards.
Miner Peter is allocating $730,000 to acquire over 1,300 GPUs for building custom mining rigs. "GPUs are the pickaxes of Ethereum mining," he says.
NVIDIA and AMD GPUs—especially RTX 30-series and RX 6000-series—are in extreme demand. Gamers face months-long waitlists while miners snap up every available unit.
To counter this, NVIDIA announced measures to limit Ethereum mining efficiency on consumer GPUs—specifically reducing hash rates on the RTX 3060. Simultaneously, they launched the Cryptocurrency Mining Processor (CMP) line—dedicated mining chips without display outputs, optimized for energy efficiency and sustained mining workloads.
Yet supply constraints persist. Some Ethereum-focused factories in Shenzhen have resorted to buying thousands of gaming laptops solely to extract their internal GPUs. According to Mars Pool CEO Shang Silin: “The resale value of extracted GPUs exceeds the cost of the entire laptop. It’s economically rational.”
This shift underscores a key difference between Bitcoin and Ethereum mining: accessibility. Ethereum’s ASIC-resistant design allows individuals to mine using standard PCs, lowering entry barriers and fueling mass participation.
Understanding Mining: A Game of Hashrate and Network Trust
To outsiders, terms like “blockchain,” “mining,” and “hashrate” can seem abstract. At its core, Bitcoin operates as a decentralized ledger—a public record of transactions maintained collectively by users rather than banks.
Every ~10 minutes, a new block is added to this chain. To do so securely without central oversight, the network uses proof-of-work (PoW), requiring miners to solve complex cryptographic puzzles using SHA-256 algorithms.
Solving these puzzles demands immense computational power—or hashrate. A single modern ASIC might take centuries to solve one block alone. Hence, most miners join mining pools, combining their hashrate to increase odds of earning rewards.
Pools distribute earnings based on contributed computing power using models like PPLNS (Pay Per Last N Shares) or PPS (Pay Per Share). This cooperative model stabilizes income and makes mining viable for smaller operators.
Network Hashrate Trends (2024–2025)
Bitcoin’s total network hashrate rose from 113 EH/s to 153 EH/s (+36%), while Ethereum surged from 142 TH/s to 281 TH/s (+99%)—nearly three times faster growth.
Ethereum’s explosive growth stems from lower entry costs and broader hardware compatibility. More participants mean greater decentralization—and greater demand for GPUs.
Miners vs. Traders: Patience Over Speculation
There’s a philosophical divide between miners and traders.
"Miners are believers," says Wang Feng, founder of Mars Finance and Mars Pool. "They see mining as dollar-cost averaging into crypto with tangible hardware."
His data shows over 90% repurchase rates among veteran miners—some upgrading equipment multiple times within months.
Li Wen agrees: “Mining is predictable. You calculate power costs, estimate output, and know your break-even point. No need for candlestick charts or leverage.”
Peter adds: “Mining removes emotional trading. You earn daily rewards regardless of price swings. It’s like long-term investing without the temptation to sell.”
Still, risks exist. Market bubbles can burst. In late 2024, when prices dipped below shutdown thresholds ("hashrate floor"), many unprofitable miners powered down. Some sold equipment at massive losses—one acquaintance lost nearly $290,000.
Yet those who held through downturns reaped enormous gains. From a low of $3,200 in late 2024 to a peak of $58,000 in early 2025, early believers saw their holdings multiply nearly 18x.

The Rise of DeFi: A New Kind of Mining
Decentralized Finance (DeFi) has introduced a new form of “mining”: liquidity mining.
Unlike traditional PoW mining, liquidity mining rewards users for depositing assets into decentralized protocols—essentially earning yield by providing capital.
By early 2025, total value locked (TVL) in DeFi surpassed $55 billion—up from $14 billion just five months prior.
While less resource-intensive than hardware mining, DeFi requires deeper technical understanding and carries smart contract risks. Still, many traditional miners diversify into DeFi to earn passive income from their holdings.
Wang Feng believes DeFi won’t replace traditional mining but will eventually integrate with it: “As DeFi grows, it increases demand for base-layer assets like ETH and BTC—driving prices up and attracting more miners.”
He likens Bitcoin to digital gold—a store of value—and Ethereum to crypto’s Android, powering dApps and innovation across Web3.
