How many cryptocurrencies have actually failed since 2021?

Since 2021, when the world seemed obsessed with cryptocurrencies, an unprecedented wave of new token projects accompanied it. These thousands of new coins entered the market with promises of revolutionary solutions, fantastic profits, and a decentralized future. But how many cryptocurrencies actually survived? The answer may be disappointing for many – most failed, taking billions of dollars of investors’ money with them.

Today, let’s look at the phenomenon of dead cryptocurrencies from a new perspective. Instead of just asking “how many projects failed,” we’ll consider how to recognize a dying coin before buying it, what mistakes teams make, and what the market has learned from these failures.

Why More Cryptocurrencies Failed Than Ever Before

Looking at the period from 2021 to 2025, we see an unstoppable trend: each year brought new waves of failures, with 2022 being particularly destructive for the sector. Driven by FOMO and speculation, investors poured capital into projects that were barely more than white papers and promises.

Low interest rates from central banks pushed investors to seek higher returns. The NFT and DeFi booms created ideal conditions for everyone to feel they could earn passive income. And indeed – on paper, many projects claimed astronomic profits. But paper can say anything.

Anatomy of a Collapse: From Squid Game Token to TerraUSD

To understand how many cryptocurrencies actually failed and why, it’s worth examining two iconic cases that show different paths to disaster.

Squid Game Token – a game without rules

In late 2021, a project called Squid Game Token (SQUID) appeared, leveraging the hype around the Netflix series. Creators promised a play-to-earn game – a system where players make money. It sounded incredible, and the token quickly appreciated, reaching prices over $2,800.

However, the project was a scam from the start. Soon after launch, the developers executed a rug pull – simply taking all the funds deposited by investors and disappearing. The token plummeted to nearly zero. These were investors who lost all their money.

Terra and UST – an ambition that collapsed

Terra was a more elaborate case. The project seemed serious – it had a team, a white paper, and a real algorithmic stablecoin called TerraUSD (UST). The idea was: UST would be pegged to the dollar through a mint-and-burn mechanism using LUNA.

In May 2022, the system collapsed. First, large players started withdrawing funds, disrupting the peg of UST to the dollar. The Luna Foundation tried to save the situation by issuing billions of USDT and selling Bitcoin reserves, but it was too late. When the peg finally broke, a chain of events ensued: people burned UST to mint new LUNA, leading to hyperinflation and a run that wiped out both UST and LUNA. Entire billion-dollar ecosystems vanished in days.

Five Deadly Cryptocurrency Mistakes

Not all failures are scams. How many cryptocurrencies failed due to simple business mistakes or poor decisions? More than we’d like to admit.

1. Rug pulls and Ponzi schemes

Some projects are scams from the start. Rug pull means developers attract investors with aggressive marketing, fake partnerships, and unrealistic promises, then disappear with the funds. Cryptocurrency Ponzi schemes operate differently – they attract new investors to pay old ones, creating an illusion of profitability until inevitable collapse.

2. Teams abandoning projects after raising funds

Many projects raised tens or hundreds of millions of dollars through token sales. Then what? The team disappears. Without further updates, development, or community support, the token quickly loses value. Sometimes even well-intentioned teams give up when their capital runs out or realize the idea is unfeasible.

3. Catastrophic tokenomics

Poorly designed token economics can destroy a project faster than bad press. If too many tokens are issued too quickly, inflation can erode value before adoption takes hold. Conversely, tokens without clear utility or reasons to hold quickly lose relevance. Healthy tokenomics require a balanced issuance schedule, real use cases, and incentives to hold, not quick sell-offs.

4. Hacks, regulation, and market crashes

Even legitimate projects can fail due to external factors. Advanced cyberattacks can drain liquidity and destroy trust. Sudden regulatory bans force exchanges to delist tokens. Market crashes, like those in 2018 and 2022, can wipe out weak coins that lack resilience to recover.

5. Lack of communication and community trust

A crypto project survives or fails depending on whether developers communicate progress. When updates are missing, the team ignores questions, or milestones aren’t met, the community quickly disperses. As community diminishes, liquidity drops, trading halts, and delisting from exchanges follows.

How to Recognize a Dead Coin Before Buying

A “dead cryptocurrency” is one that has ceased to function as an active project. Here are warning signs:

• Removed from major exchanges – if you can’t trade the token on any reputable platform, it’s a bad sign
• Silence on social media – no posts, updates, or communication from the team for months is a serious alarm
• Abandoned code repositories – if the code hasn’t been updated in a long time, the project is effectively dead
• Almost zero trading volume – no buyers or sellers indicates no interest or liquidity

How Many Cryptocurrencies Have Ended – A New Sector Outlook

Data from 2021 to 2025 reveal a sobering reality. Thousands of tokens were created, but most didn’t survive more than one market cycle. The rise in failures was especially sharp in 2022 – a year of major market cleansing.

However, this “cleansing” also had positive effects. Investors became more skeptical of hype. Regulators started acting more decisively. Projects that wanted to survive had to demonstrate real value, not just pretty promises.

What the Future Holds for Cryptocurrencies

With improved regulation and increased investor awareness, survival rates may improve. Clearer rules can eliminate scammers. Informed investors will be more cautious about projects based solely on hype. This could create a healthy market where genuine, well-managed projects thrive.

How many cryptocurrencies will survive in the coming years? It will depend on investors’ due diligence, the real utility of projects, and the strength of their communities. Coins that offer real solutions and show active development have a good chance of lasting. The market is gradually shifting from a mass of weak projects to fewer, more resilient, and trustworthy cryptocurrencies.
