In the early days of cryptocurrency, few could have predicted the seismic shifts that would ripple through finance, technology, and individual lives. This is the story of Kevin, a 33-year-old IC design engineer who became an unlikely entrepreneur during Bitcoin’s volatile rise in 2013—turning technical expertise into a thriving online business teaching others how to mine digital gold.
The Birth of a Digital Dream
Kevin hadn’t planned on becoming a Bitcoin educator. By day, he worked in semiconductor R&D. But by night, he led a private QQ group of over 1,000 tech-savvy users fascinated by blockchain and decentralized currency. What started as casual discussions about cryptography soon evolved into something far more consequential.
Bitcoin, originally developed by cryptographers and tech enthusiasts in the U.S., had reached China by 2011. It functioned as a peer-to-peer electronic cash system secured through complex computational puzzles—a process known as mining. Miners used computing power to validate transactions and were rewarded with newly minted bitcoins. With a capped supply of 21 million coins (expected to be fully mined by 2140), scarcity gave Bitcoin its allure.
For Kevin, it wasn’t just ideology—it was opportunity. While skeptics dismissed Bitcoin as digital fantasy, he saw potential: limited supply, growing demand, and no central authority. To him, it was the ultimate hedge against inflation, surpassing even gold.

A Hardware Revolution Sparks Opportunity
In March 2013, a friend revealed he was working on a secret chip project—one designed specifically for Bitcoin mining. At the time, general-purpose GPUs were being used for mining, but efficiency was low. Specialized hardware called ASICs (Application-Specific Integrated Circuits) promised massive gains in processing speed.
The U.S.-based Avalon miner had just launched, but availability in China was nearly zero. Enter “Dr. Pumpkin,” a mysterious figure claiming to have built a high-efficiency ASIC miner capable of generating returns worth over $88 per month. Sold for 8,000 yuan ($1,250) via pre-order on Taobao, demand exploded—even though the device didn’t yet exist.
Kevin’s friend took a different approach: selling ready-to-ship miners at 3,000 yuan each. Within a month, they sold over 100 units. That success lit a fire under Kevin.
He opened his own Taobao store in late March with a bold offer:
“600 yuan tuition—hands-on guidance to build your mining operation from scratch. Bitcoin payments accepted.”
His course included:
- Basic Bitcoin theory (4 yuan per module)
- Step-by-step mining setup
- Remote troubleshooting for GPU and ASIC mining rigs
- Personalized QQ-based coaching
Within weeks, his QQ group surpassed 1,000 members. By April 10—the day Bitcoin hit $266—he held 70 BTC, worth nearly 120,000 yuan ($19,000). The dream felt real.
Riding the Rollercoaster
By August, Kevin’s tutorial sales stabilized at 1,888 monthly transactions. But miners began complaining: “My rig hasn’t found a block in three days.” Mining difficulty had surged as more players joined the network.
Yet paradoxically, Bitcoin’s price soared—from 780 yuan to over 1,200 yuan by November. Media buzz grew. Even “aunties” (middle-aged women investors) started asking about buying coins.
Kevin’s role shifted. He was no longer just a tutor—he became a de facto market analyst. Traders flooded his inbox with questions about price trends, entry points, and portfolio strategy. Sleep became rare; markets never closed.
Then came the crash.
On October 3, news broke that the FBI shut down Silk Road—the infamous darknet marketplace using Bitcoin—and seized 26,000 BTC. Global prices plunged. Chinese exchanges dropped from 780 to 690 yuan overnight.
But Kevin sensed opportunity. He doubled down, buying more coins while advising his group: “This dip won’t last.”
He was right.
By mid-November, Bitcoin rocketed past $800. On November 27, it breached $1,100—surpassing the price of gold. Newcomers dreamed of buying BMWs with their holdings.
But Kevin felt uneasy.
“One coin went from fractions of a cent to $1,200. Is this sustainable?” he typed into the chat—then deleted the message.
No one answered. Euphoria ruled.
The Hidden Hierarchy of the Bitcoin World
Behind the scenes, Bitcoin’s ecosystem had stratified into layers:
- Miners: The base layer producing new coins.
- Educators & Consultants: Like Kevin, monetizing knowledge.
- Traders & Market Movers: Figures like Zhuang Jianchou and Su Daji—who influenced prices through large QQ trading groups.
- Hardware Makers: Teams like ASICME and “Kao Mao” (Fried Cat), producing powerful mining rigs.
- Institutional Players: Visionaries like Li Xiaolai (China’s Bitcoin billionaire) and Yang Linke (co-founder of BTCChina), shaping policy, funds, and public perception.
These "gurus" promoted Bitcoin aggressively—but admitted its speculative nature.
“Most people aren’t buying because they believe in decentralization,” said financial analyst Duan Hongbin. “They want quick profits.”
And therein lay the danger.

FAQ: Understanding Bitcoin's Early Days
Q: What is Bitcoin mining?
A: Mining involves using computer hardware to solve cryptographic puzzles that verify transactions on the blockchain. Successful miners are rewarded with new bitcoins.
Q: Why did early miners use GPUs and ASICs?
A: GPUs offered flexibility for early mining; ASICs later emerged as specialized chips far more efficient at solving Bitcoin’s SHA-256 algorithm.
Q: Was Bitcoin legal in China back then?
A: While not outright banned until later years, regulatory uncertainty loomed. Exchanges operated in gray zones with minimal oversight.
Q: How did people learn about Bitcoin in 2013?
A: Through forums, QQ groups, tech blogs, and word-of-mouth—education was decentralized and community-driven.
Q: Why did some exchanges fail?
A: Many lacked transparency. User funds were often stored in personal accounts rather than secure wallets, making them vulnerable to fraud or theft.
The Crash That Changed Everything
On October 26, Hong Kong-based exchange GBL vanished overnight. Hackers posted ransom notes on its homepage; staff disappeared. Over 344 users lost 10.2 million yuan (~$1.6M).
Shockingly, the mastermind was linked to “Zhuang Jianchou,” one of the very traders who once shaped market sentiment.
The lesson was clear: in an unregulated space, trust is fragile. As Hong Kong Financial Secretary John Tsang warned:
“If Bitcoin rises too fast, no one will spend it. If it crashes, no one will accept it.”
Stepping Away at the Peak
By late November, Kevin made his move.
He updated his QQ group announcement:
“No private chats unless there’s an issue with course payment.”
Confusion spread. “Is he cashing out?” “Will BTC hit 1200?”
He ignored them all.
Over several hours on December 1st, he sold off 50+ BTC in staggered trades. Only five remained when a final message popped up:
“Heard you’re selling—can I buy a few directly?”
Kevin didn’t reply.
He logged off.
For the first time in months… he slept soundly.
Final Thoughts: Knowledge Was the Real Gold
Kevin’s story reflects a pivotal moment in crypto history—a time when curiosity met chaos, and information became currency. He didn’t get rich from mining alone; he profited by empowering others.
Today’s market is more mature, but the core truth remains: understanding beats guessing.
