In the fast-evolving world of blockchain and cryptocurrency, few figures embody resilience, innovation, and long-term vision quite like Mao Shixing, widely known in the community as "Shen Yu" (Divine Fish). His journey—from a curious university student discovering Bitcoin in 2011 to becoming a foundational force behind one of China’s earliest mining pools and a leading crypto wallet—offers profound insights into the volatile yet transformative nature of digital assets.
This is not just a story of early adoption or technical brilliance. It’s a narrative about risk, recovery, and the quiet strength required to hold onto wealth in an industry defined by chaos.
The Spark: Two News Articles That Changed Everything
Mao Shixing first encountered Bitcoin in 2011 while studying information engineering at university. Two news articles sparked his curiosity—what was this digital currency that claimed to solve the double-spending problem without relying on centralized authorities?
Driven by intellectual fascination, he dove into Bitcoin’s whitepaper and the global forums where pioneers like Satoshi Nakamoto once engaged. On Bitcointalk, he spent three months absorbing every thread, grasping not just how Bitcoin worked, but why it mattered.
“I felt the world had suddenly become incredibly exciting,” Shen Yu recalls.
Back then, blockchain wasn’t yet a buzzword. The ecosystem was small, technical, and idealistic. Most participants were tech enthusiasts and cryptographers, not speculators. Inspired by his cryptography background—same as Satoshi’s entry point—Shen Yu saw mining not as a get-rich-quick scheme, but as a cryptographic game worth mastering.

He began mining with GPUs at home, building what amounted to a personal home-based mining farm. With low competition and minimal difficulty, he accumulated his first significant stash of Bitcoin—setting the stage for what would become a pioneering career.
Founding F2Pool: Building Trust in a Wild West Market
By 2013, Bitcoin’s price surged from $200 to over $1,000, drawing massive interest. The arrival of ASIC miners disrupted the GPU-dominated landscape, creating a power shift—and an opportunity.
Then a first-year graduate student, Shen Yu made a bold decision: drop out to launch China’s first Chinese-language Bitcoin mining pool—F2Pool (later nicknamed “Fish Pool”).
At the time, mining pools were chaotic. Many operators disappeared overnight ("ran away"), leaving miners unpaid. Trust was scarce.
Shen Yu’s solution? A new reward model:
- Distribute earnings based on theoretical difficulty, absorbing bad luck or technical failures himself.
- Guarantee payouts within 24 hours—so even if the pool vanished, miners lost no more than one day’s income.
It was revolutionary—and costly. F2Pool operated at a loss for months. In July 2013, with reserves depleted, Shen Yu announced shutdown.
But something unexpected happened.
Miners refused to leave.
Moved by their loyalty, the team raised 2,100 BTC as collateral and pressed on. Then came another crisis: a sustained DDoS attack, so powerful it ranked among the top attacks globally that year. Servers were rejected by data centers simply for bringing down infrastructure.
For three months, the team worked 24/7, rewriting protocols until they achieved permanent defense.
Their perseverance paid off. By 2015, F2Pool became the world’s largest Bitcoin mining pool, controlling up to one-third of global hash power. It later expanded into Ethereum and Litecoin, playing a key role in activating SegWit on the Litecoin network.
The Crash: Lessons from One Coin's Rise and Fall
Despite early success, 2013–2014 brought harsh reality. As speculation replaced technical discourse, Shen Yu watched the market inflate—and then collapse.
Recognizing the need for education, he co-founded 1Bite (Yi Bi Te), a media company focused on blockchain literacy. But irony struck: the educators became victims.
An internal project—Silver Fish Litecoin miner—failed due to crashing prices. Mining operations ran only at night to save on electricity, then stopped entirely when revenue couldn’t cover costs.
By 2015, 1Bite faced liquidation.
“It was devastating,” Shen Yu admits. “We went from rapid growth to total loss. Internally, everything broke down.”
He stepped away from the industry, returning home to reflect. From this pain came wisdom:
1. Stay cautious in bear markets—never over-expand.
2. Keep enough liquidity—aim for two years of operating funds.
3. Survival is victory when others fall.
These lessons proved vital when he returned in 2016—as Bitcoin rebounded and F2Pool entered its golden era.
Cobo Wallet: Securing the Future of Digital Assets
In 2017, disaster struck again—not from market swings, but security flaws.
Due to vulnerabilities in cloud infrastructure and Ethereum upgrades, F2Pool lost over 8,000 ETH (worth nearly $10 million at peak). Though the team covered losses to protect users, Shen Yu realized two systemic threats:
- Sophisticated hackers using automated tools.
- User error: Most wallets forced individuals to manage private keys—a recipe for theft.
His response? Co-found Cobo Wallet with Dr. Jiang Changhao (creator of China’s first Bitcoin wallet). Unlike others, Cobo focused on institutional-grade security with enterprise custody solutions and hardware-backed protection.
But Shen Yu saw deeper potential:
“Wallets are the gateway to Web3—the front door of the decentralized internet.”
Today, wallets aren’t just storage; they’re identity hubs, DeFi gateways, and NFT vaults. By securing this critical entry point, Cobo positioned itself at the heart of blockchain adoption.

Love, Legacy, and a Blockchain Wedding Ring
Beyond tech and turmoil, Shen Yu’s story has a human side—one etched permanently into the blockchain.
In 2012, he met his wife “White Shark” in a Bitcoin QQ group. On their wedding day in 2014, instead of a diamond ring, he gifted her something eternal: a mined Bitcoin block.
He calculated an address starting with “1LoveU” (took 18 hours), embedded the message “Zhi zi zhi shou, yu zi xie lao” (“Hold your hand, grow old with you”) into two consecutive blocks—and stored them forever on-chain.
“Bitcoin and love are both faith,” he says quietly.
It’s a poetic metaphor: both require trust, patience, and belief in something invisible yet powerful.
The Philosophy of "Steady": Surviving Storms with Calm
When asked to describe himself in five words, Shen Yu replied: “One is enough—steady.”
After cycles of boom and bust—from sudden wealth at age 23 to losing millions overnight—his mindset evolved.
“People say seven years make a lifetime. I feel like I’ve lived several.”
He no longer chases hype. His approach reflects deep maturity:
- Emotionally grounded amid price swings.
- Strategically patient during bear markets.
- Focused on sustainable innovation over shortcuts.
Opportunities come in four phases:
- You don’t see them (unseen)
- You mock them (underestimated)
- You don’t understand them (confusing)
- You miss them (too late)
Shen Yu didn’t just catch the wave—he learned how to ride it through storms.
