The blockchain and cryptocurrency landscape has undergone dramatic transformations in recent years—marked by explosive growth, high-profile collapses, and resilient innovation. For newcomers and seasoned observers alike, understanding this evolution is key to navigating the future of digital finance. This article explores pivotal moments from 2021 through 2025, highlighting how market dynamics, technological breakthroughs, and institutional adoption have shaped today’s crypto ecosystem.
2021: The NFT Boom and Bitcoin Goes Mainstream
The global pandemic accelerated digital transformation across industries, and blockchain was no exception. With remote lifestyles becoming the norm, decentralized applications saw unprecedented adoption—especially in gaming and digital art.
In March 2021, a landmark moment occurred when Christie’s auction house sold Everydays: The First 5000 Days, a digital artwork by artist Beeple, for $69 million—the highest price ever paid for an NFT at the time. This sale catapulted NFTs (Non-Fungible Tokens) into mainstream consciousness, proving that digital ownership could carry real-world value.

Shortly after, in April 2021, the Bored Ape Yacht Club (BAYC) launched as a collection of 10,000 unique algorithmically generated apes. Initially overlooked, strategic marketing and celebrity endorsements—including figures like Snoop Dogg and Eminem—turned BAYC into one of the most valuable NFT brands globally. Some individual apes sold for over $1 million, cementing NFTs as both cultural icons and investment assets.
Another historic milestone came in September 2021 when El Salvador became the first country to adopt Bitcoin as legal tender alongside the U.S. dollar. The bold move signaled growing governmental interest in cryptocurrency and sparked debates worldwide about financial sovereignty and inclusion.
While controversial, El Salvador’s bet appeared visionary as Bitcoin surged toward $73,000 in later years—validating early confidence in its long-term potential.
2022: The Collapse of UST and the LUNA Death Spiral
After Bitcoin hit an all-time high of $69,000 in November 2021, the market began cooling amid rising inflation and tightening monetary policies. By May 2022, a perfect storm hit the crypto world with the collapse of TerraUSD (UST), a so-called “algorithmic stablecoin” pegged to the U.S. dollar.
UST maintained its peg not through reserves but via a complex mechanism involving its sister token, LUNA. When a large withdrawal of $150 million in UST liquidity triggered panic selling—starting with a mysterious new wallet holding $84 million—confidence quickly eroded.
As users rushed to dump UST, the system minted more LUNA to absorb the sell pressure, leading to hyperinflation of the token. Within days, both UST and LUNA lost nearly all value, wiping out over $500 billion in market capitalization across the ecosystem.
This event, known as the "death spiral," exposed critical flaws in algorithmic stablecoins and raised serious questions about risk management in decentralized finance (DeFi). Rumors persist that well-capitalized institutional players may have orchestrated the crash—but no party has claimed responsibility.
The FTX Implosion: Trust Erodes
Just months after the LUNA disaster, another shockwave rocked the industry: the sudden collapse of FTX, once the second-largest cryptocurrency exchange globally.
In November 2022, investigative reports revealed that FTX had insufficient liquidity and was allegedly using customer funds to cover losses at its affiliated trading firm, Alameda Research. With liabilities exceeding $8 billion and only minimal cash on hand, users scrambled to withdraw assets—only to find withdrawals suspended.
Even Binance, initially poised to acquire FTX, backed out after due diligence uncovered insurmountable financial issues. Within two weeks, FTX filed for bankruptcy.
Sam Bankman-Fried (SBF), once hailed by Time magazine as a top influencer, became synonymous with corporate misconduct. The fallout affected countless investors worldwide—including third-party platforms like Steaker—that had entrusted significant funds to FTX.
The incident underscored the need for greater transparency, regulation, and secure custody solutions in crypto.

2022: Polygon Rises Amid Market Downturn
While much of 2022 was defined by crisis, Polygon emerged as a bright spot. Positioned as a scaling solution for Ethereum, Polygon addressed network congestion and high gas fees—long-standing pain points for users.
By enabling faster and cheaper transactions while maintaining Ethereum’s security model, Polygon attracted numerous NFT, GameFi, and DeFi projects. Despite broader market declines, Polygon reported a 156% year-on-year increase in protocol revenue, reaching nearly $26 million in 2022.
Its success highlighted a crucial truth: even during bear markets, foundational infrastructure development continues—laying the groundwork for future growth.
2023: Real-World Assets (RWA) Gain Momentum
As interest rates remained elevated and speculative fervor cooled, attention shifted toward tangible value. Enter Real-World Assets (RWA)—a trend that bridges traditional finance with blockchain technology.
RWA involves tokenizing physical assets such as real estate, bonds, or commodities into digital tokens on a blockchain. This innovation lowers entry barriers for investors, improves liquidity, and reduces administrative costs.
Projects began emerging that allowed fractional ownership of luxury properties or treasury-backed securities—all tradable 24/7 on decentralized platforms. Institutional players took notice, recognizing RWA as a pathway to integrate legacy financial systems with Web3 efficiency.
This fusion of old and new finance signaled a maturing ecosystem where utility began to outweigh hype.
Web2 Giants Enter the Crypto Arena
Major financial institutions also stepped up their crypto involvement. PayPal launched its own U.S. dollar-pegged stablecoin, PYUSD, enabling seamless transfers between fiat and digital currencies. Meanwhile, Visa and Mastercard expanded their blockchain payment rails, integrating crypto settlements into existing networks.
These moves demonstrated that despite volatility, large corporations view digital assets as inevitable components of the future financial stack.
2024–2025: Bitcoin Shines Again
After more than a decade of rejections, the U.S. Securities and Exchange Commission (SEC) approved the first spot Bitcoin ETF in early 2024. This landmark decision marked official regulatory recognition of Bitcoin as a legitimate asset class—boosting investor confidence and unlocking institutional capital flows.
Simultaneously, Bitcoin underwent its fourth halving event on April 20, 2024 (UTC), reducing block rewards from 6.25 to 3.125 BTC. Historically, halvings have preceded bull markets due to constrained supply amid steady demand—a pattern many believe repeated in 2025.
With ETF inflows and scarcity dynamics aligning, Bitcoin surpassed previous highs, reinforcing its status as digital gold.
Frequently Asked Questions
Q: What caused the UST-LUNA crash?
A: The collapse stemmed from a loss of confidence in UST’s dollar peg, exacerbated by its algorithmic design. Massive withdrawals triggered a feedback loop where increasing LUNA supply drove its price to zero.
Q: Can such crashes happen again?
A: While risks remain, especially in undercollateralized systems, increased scrutiny and better-designed protocols reduce the likelihood of identical failures.
Q: Why are RWAs important?
A: They bring real economic value onto blockchains, allowing broader participation and creating yield opportunities backed by actual assets.
Q: Is Bitcoin safe after the ETF approval?
A: ETFs add legitimacy and improve accessibility but don’t eliminate market risk. Price volatility still exists based on macroeconomic factors.
Q: How did Polygon succeed during a bear market?
A: By focusing on solving real user problems—high fees and slow speeds—it attracted developers building long-term applications regardless of price cycles.
Q: What does FTX’s collapse mean for exchanges today?
A: It led to stronger calls for proof-of-reserves audits and regulatory oversight—now standard practices among reputable platforms.
The journey from NFT mania to regulatory milestones reflects crypto’s resilience. Though setbacks occurred, each crisis brought lessons that strengthened the foundation.
