The cryptocurrency and blockchain sector experienced explosive growth in 2021, particularly in decentralized finance (DeFi) and non-fungible tokens (NFTs). This year was marked by price volatility, institutional adoption, and the rise of next-generation smart contract platforms—all reflected in this definitive list of the industry's top winners and losers.
🏆 2021's Biggest Winners
1. Kazakhstan: The New Bitcoin Mining Hub
When China banned Bitcoin mining in May 2021, Kazakhstan emerged as a key beneficiary, leveraging its coal-based energy infrastructure to attract displaced miners. By July, the nation accounted for 18.1% of global Bitcoin hash rate, up from just 1.4% in 2019 (Cambridge Centre for Alternative Finance).
Key Insight: Despite winter power shortages threatening its dominance, Kazakhstan’s rapid ascent reshaped the mining landscape.
2. Coinbase: Pioneering Crypto’s Public Market Debut
Coinbase’s April NASDAQ listing (ticker: COIN) marked a milestone, achieving an **$86 billion valuation** on its first trading day. Though shares later stabilized at ~$243, its IPO validated crypto’s mainstream potential.

3. Solana: The Ethereum Challenger
Solana’s proof-of-stake network, boasting 50,000 TPS (vs. Ethereum’s 30), became a magnet for DeFi and NFT projects. Its native token, SOL, surged to become the fifth-largest cryptocurrency by market cap.
Pro Tip: Solana’s speed comes with trade-offs—watch for network stability under peak loads.
4. Nayib Bukele & El Salvador: Bitcoin as Legal Tender
El Salvador’s bold move to adopt Bitcoin (BTC) as legal tender included:
- $30 BTC airdrops to citizens
- Volcano-powered mining
- Plans for Bitcoin City, funded by a $1B BTC bond
Controversy: While hailed as innovative, the policy faces scrutiny over economic impact and volatility risks.
5. Beeple: The NFT Pioneer
Digital artist Beeple’s Everydays: The First 5000 Days NFT sold for $69.3 million at Christie’s, catapulting NFTs into mainstream awareness.
📉 2021’s Notable Losers
1. Meta (Diem): The Failed Stablecoin
Facebook’s rebranded Diem project lost momentum amid regulatory pushback and executive departures. The New York Times noted its “confusing rebranding” as a symptom of deeper struggles.
2. Nigeria’s Central Bank: Losing the Crypto Battle
A February 2021 ban on crypto transactions backfired—Nigeria now hosts the world’s second-largest P2P Bitcoin market, proving resilient demand.
3. Iron Finance: The "World’s First Crypto Bank Run"
Collateralized by the unstable TITAN token, Iron Finance’s IRON stablecoin collapsed in June, evaporating $2 billion+ in value within hours.
Lesson: Over-reliance on volatile collateral undermines stablecoin integrity.
