The cryptocurrency world moves at lightning speed. What’s hot today can vanish tomorrow — and yet, the cycle repeats itself with eerie consistency. In mid-2020, decentralized finance (DeFi) ignited a speculative frenzy that reshaped the crypto landscape overnight. It wasn't just about innovation; it was about explosive gains, overnight millionaires, and a new class of digital investors riding the wave — only to be swept away by the next tide.
This is the story of that surge — a moment when DeFi, liquidity mining, and altcoin mania collided to create one of the most intense market cycles in recent memory.
The Spark: How Compound Lit the Fire
In June 2025, Compound, a leading DeFi lending protocol, introduced a game-changing incentive model: liquidity mining. By rewarding users with its governance token COMP for providing liquidity, Compound turned passive participation into high-yield speculation.
The results were explosive.
Within just three days, COMP’s price surged sixfold, capturing the imagination of traders and developers alike. But more importantly, it unlocked a blueprint for rapid growth — one that required no traditional marketing, no venture capital endorsements, and no centralized exchange listings.

The message was clear: if you provided capital, you could earn outsized returns. And so began the gold rush.
The Altcoin Explosion: From NEST to JST
As momentum built, other projects rushed to replicate Compound’s success. The term "DeFi" became a magic label — attach it to your project, launch a token, and suddenly you had a shot at exponential growth.
By July 2025, the total crypto market cap had climbed from $263 billion to $351 billion — a 33.5% increase in just one month. But beneath this broad rise lay staggering individual performances:
- NEST rose from $0.023 to $0.1872 — an 8x gain.
- BAND jumped from $1.11 to $17.22 — over 15x appreciation.
- JST, a new DeFi-themed token launched by TRON founder Justin Sun, multiplied 17 times in value.
Investors began drawing comparisons to the 2017 ICO boom. “It feels like 2017 all over again,” said investor Xiaoyang. “I missed one coin — someone showed it to me — now it’s up 20x.”
This wasn’t isolated speculation. It was systemic — driven by FOMO (fear of missing out), social sentiment, and a belief that early participation equaled guaranteed profits.
The New Hierarchy: Rise of the "New韭菜" (New Lambs)
In Chinese crypto slang, long-time investors are often called “laoshe” (old lambs), referring to those repeatedly “sheared” or “harvested” during market cycles. But during the DeFi surge, a new hierarchy emerged: the "new lambs."
Who were they?
Not necessarily newcomers — but those who embraced DeFi tokens like LINK, YFI, or CRV while abandoning traditional assets like Bitcoin or Ethereum.
One trader put it bluntly:
“If your watchlist doesn’t have a 20% gain or a coin that doubled last week, you’ve already been left behind. The wheel of time rolled over your face.”
To many, Bitcoin and Ethereum began to feel like blue-chip stocks — stable, valuable, but painfully slow. Meanwhile, DeFi tokens resembled high-growth tech IPOs on steroids.
An investor named Lifeng compared them directly:
“DeFi coins are like科创板 (STAR Market) stocks — they make you question reality with their speed. BTC and ETH? They’re bank stocks. Everyone agrees they’re solid — but they don’t move.”
And here lies the irony: the ones making money were now labeled "new lambs," not because they were naive, but because history suggested their gains wouldn’t last.
Liquidity Mining: Innovation or Illusion?
At its core, liquidity mining allowed users to earn tokens by supplying assets to DeFi protocols — similar in concept to staking or yield farming.
But unlike earlier models like “transaction mining” or “lock-up mining,” liquidity mining operated entirely on-chain and permissionlessly. There was no gatekeeper. No KYC. Just code.
Projects sprouted overnight. All it took was:
- Deploy a smart contract
- Launch a token
- Reward early liquidity providers
Costs plummeted. Time-to-market collapsed. A full launch cycle that once took months now happened in hours.
As one observer quipped:
“ICO required whitepapers, roadmaps, private sales… DeFi? Just send money.”
Yet beneath the surface, questions lingered. Was this real utility? Or just financial engineering wrapped in decentralization theater?
Vitalik Buterin weighed in cautiously:
“I haven’t participated in any liquidity mining schemes. Without understanding the mechanics, don’t blindly follow trends. There are many other valuable Ethereum DApps beyond today’s ‘hottest’ projects.”
His warning came just before disaster struck.
The Crash: Yam Finance and the 36-Hour Collapse
On August 14, 2025, Yam Finance (YAM) — a highly anticipated yield-optimizing protocol — launched with massive hype and $600 million in locked value within 36 hours.
Then came the bug.
A critical flaw in its rebase mechanism caused the token supply to spiral out of control. Within minutes, YAM’s price crashed from $160 to under $1 — a 98.8% drop.

The fallout was immediate:
- CRV (Curve DAO Token) dropped 95% from its peak.
- Entire DeFi portfolios evaporated.
- One investor reported losing 99% of a ¥100,000 investment — down to ¥860.
A popular joke spread across forums:
“Yesterday I was digging potatoes (YAM), now they’re gone. Today I’m mining CRV — straight into a ditch.”
But even in collapse, patterns repeated.
Within days, LINK broke new highs again, reaching $19.30. Mainstream coins rebounded. The capital didn’t leave — it rotated.
As analyst Niu Sheng observed:
“It’s not about new money. It’s capital recycling — old players chasing new narratives. One group gets cut down, another rises. Cut, hype, regrow. Again and again.”
FAQ: Understanding the DeFi Cycle
Q: What caused the 2025 DeFi boom?
The boom was triggered by Compound’s liquidity mining model, which rewarded users with COMP tokens for lending/borrowing. This sparked copycat projects offering high yields through token emissions.
Q: Are DeFi tokens safe investments?
Many DeFi tokens carry high risk due to unproven business models, smart contract vulnerabilities (like Yam), and speculative trading. Always conduct thorough research before investing.
Q: Why do altcoins rise so fast during DeFi seasons?
Low float supply, community-driven hype, and yield incentives create perfect conditions for rapid price appreciation — especially when combined with FOMO-driven trading.
Q: Is DeFi just another bubble?
While some projects lack sustainable value, others are building real financial infrastructure. The challenge lies in distinguishing between speculation and genuine innovation.
Q: Can Bitcoin compete with DeFi returns?
Bitcoin prioritizes security and scarcity over yield. While it rarely matches short-term DeFi gains, it remains the anchor asset of the crypto economy due to its resilience and adoption.
Q: Will this cycle repeat?
Historically, yes. Every major trend — from ICOs to futures to NFTs — follows a similar arc: innovation → speculation → crash → rebirth. DeFi fits this pattern precisely.
The Endless Cycle: Innovation, Speculation, Repeat
DeFi promised freedom from intermediaries — yet ended up creating new forms of extraction. Transparency didn’t eliminate manipulation; it merely shifted power to those with coding skills and fast reflexes.
Blockchain once aimed to disrupt finance. Now, much of it functions as a high-speed casino for digital assets.
Yet despite crashes like Yam and CRV’s collapse, interest persists. Total value locked (TVL) in DeFi protocols continued rising — up 30% in one week alone after the crash.
Why?
Because beneath the noise lies an undeniable truth:
Crypto offers unregulated access to outsized returns — fleeting as they may be.
For some, it’s about building the future of finance. For most, it’s about catching the next wave before it crests.
And somewhere out there, already forming, is the next generation of "new lambs" — waiting to be harvested.

Final Thoughts
The 2025 DeFi surge wasn’t just about technology — it was about human behavior writ large on a public ledger. Greed, fear, innovation, and folly played out in real time across global markets.
Core keywords naturally integrated throughout: DeFi, liquidity mining, altcoin, crypto market, yield farming, smart contract risk, FOMO, token speculation.
While regulators tighten oversight elsewhere, crypto remains one of the last frontiers for unchecked financial experimentation — for better or worse.
