Five major cryptocurrencies that promised the future and are now almost extinct

A small number of tokens are generated every cycle, and they are not only traded, but also believed. They are accompanied by a founder who delivers a keynote speech, a white paper that reads like a manifesto, and a promise that goes far beyond the price: the project will replace cloud services, connect all blockchains, or put a billion devices on the chain. Then the cycle ends. and then it ends.

The market background makes this contrast cruel. After Bitcoin reached a peak of approximately US$126,000 in October 2025, it is currently trading in the range of US$64,000 to US$65,000. The total market value of cryptocurrency is close to US$2.17 trillion. The Bitcoin dominance rate exceeds 56%. The Fear and Greed Index is still in the fear range. Capital does not flow down the risk curve. It stagnates.

This means that the decline of these coins below is not due to a bad week. They fell because two full cycles have passed and they have never returned to where they started. Here are five of the most eye-catching examples, ranked by decline from historical highs.

5. Cosmos (ATOM): What happened to the blockchain Internet?

Cosmos was supposed to be the connected organization of the encrypted world. An SDK for building any blockchain, a protocol (IBC) for them to communicate with each other, and a central hub with ATOM as the security core. In 2021,"blockchain Internet" is one of the most powerful narratives in the market.

Status:

Strangely enough, this technology has been largely successful. The Cosmos SDK later drove Celestia, Impressive, dYdX, Sei and Terra. IBC is still transmitting real transaction volume. The failure is the token itself. Each chain started using the Cosmos tool launched its own token, its own verification node, and its own fee revenue, and dYdX eventually built its own chain and took away its business. ATOM protected the hub but captured almost nothing. The "ATOM 2.0" proposal in 2022 that attempted to address this issue was voted down by the community. Jae Kwon's departure and years of governance infighting completed the rest of the work.

Price:

ATOM is trading at approximately US$1.39, compared with a historical high of approximately US$44.70 in September 2021. This is down about 96.8% from its peak, with a market value of approximately $727 million.

4. Algorand (ALGO): Can academic credibility save a token?

Algorand has the best resume in the industry. Founded by Silvio Micali, a professor at the Massachusetts Institute of Technology and a Turing Award winner, it introduces a pure proof of stake mechanism with instant finality and no forks, and positions itself as a chain that institutions and governments will actually use. It has received FIFA World Cup sponsorship as well as a series of central bank and government pilot projects.

Status:

The chain still operates exactly as advertised. Blocks are fast, cost a fraction of a penny, and there has never been a serious outage. But developers have turned to the Ethereum Layer 2 network and Solana. DeFi liquidity has never arrived on a large scale, and pilot projects have rarely translated into sustained on-chain transaction volume. Algorand is currently positioning itself around post-quantum security and real-world assets, which is indeed a differentiated advantage, but so far it has been more a technical advantage than a demand advantage. ALGO hit a record low in March 2026.

Price:

ALGO is trading at close to US$0.084, compared with an all-time high of US$3.56 in June 2019, a decrease of approximately 97.6% from the peak, and a market value of approximately US$758 million.

3. IOTA: What is left of IoT tokens?

IOTA was supposed to become the machine economy. No blocks, no miners, no fees. Instead, there is a directed acyclic graph called "entanglement", where each transaction confirms two others, which in theory means that as transaction volume increases, the network becomes faster. Fridges pay for their own repairs, cars pay for their own parking, and sensors sell data. At the end of 2017, this story pushed it into the top five tokens.

Status:

A machine-free economy was never realized. In 2017, a "Microsoft partnership" ultimately turned out to be just a data market pilot, damaging credibility; the Trinity wallet was breached in 2020, forcing the team to suspend the entire network for several weeks; and the founding team was openly divided. IOTA has since been rebuilt from almost zero to become a Move-based, DAG consensus-based first-layer network targeting DeFi and real-world assets. This is a reasonable technical reset, but it is also completely different from the products people bought in 2017, and the market prices them accordingly. The token is currently basically at an all-time low.

Price:

IOTA is trading at approximately US$0.035, compared with the historical high of US$5.25 in December 2017, down approximately 99.3% from the peak, and has a market value of approximately US$158 million.

2. EOS / Vaulta (A): What did $4.1 billion buy?

Largest initial coin offering in history. Block.one conducted a year-long token sale that raised approximately $4.1 billion to create an "Ethereum killer" that aims to process millions of transactions per second with zero fees. At the time, it was the most well-funded project in the crypto space.

Status:

The U.S. Securities and Exchange Commission reached a $24 million settlement with Block.one in 2019, a fraction of the amount raised. The promised throughput was achieved, but the application did not. The community has struggled with Block.one for years over unspent funds and unfulfilled promises. In 2025, the network will change its name to Vaulta, focusing on Web3 banking, and its token code will be changed from EOS to A. The name change brought a brief rise, then collapsed: it hit a record low in January 2026, fell to about $0.057 in June 2026, and the CEO who led the transformation resigned.

Price:

Vaulta is trading at close to US$0.06, while EOS's all-time high in April 2018 was US$22.89, down approximately 99.6% from its peak, and its market value is approximately US$105 million.

1. Internet Computer (ICP): How does a token drop by 99.7%?

The most ambitious vision in the 2021 cycle. Dfinity spent more than $500 million in research and development to build a blockchain that can host entire applications end-to-end, replacing AWS, Google Cloud and traditional web stacks. Websites, databases, front-ends and payments all run on the chain. It is described as no less than a decentralized Internet.

Status:

ICP will be launched in May 2021 and its peak valuation has an implied market value of nearly US$400 billion, making it one of the largest technology assets on the planet. Early allocations then unlocked, the market fell, and prices collapsed almost immediately. The technology is indeed unique and still iterative, including ckBTC, on-chain AI experiments, and the "Mission 70" proposal released in February 2026 (plans to reduce token inflation by at least 70% by 2027). But inflation has never been the core issue. The problem is usage. Every application on the network destroys the ICP, so the fix will only take effect when the application arrives.

Price:

The ICP trading price is approximately US$2.15, compared with the historical high of US$700.65 in May 2021, a decrease of approximately 99.7% from the peak, and the market value is approximately US$1.2 billion.

What do these five projects have in common?

None of these projects are scams, and none of them are technically dead. Each network still produces blocks. Each team is still delivering. This is why this list is interesting rather than just frustrating.

pattern is not fraud, but three recurring errors:

The token is not the product itself.

Cosmos is the purest example. Technology wins, but tokens lose because value accumulates into the chain built on it, not the chain at the center.

Supply comes before demand.

Both ICP and EOS entered the market with huge valuations and huge unlock plans, a mathematical resistance that no engineering fix can overcome.

Narratives expire faster than roadmap.

IOTA's machine economy and Algorand's institutional vision are theories that will take years, and the market re-prices every 90 days. When the product is ready, the story belongs to someone else.

Are there any of these tokens worth noting?

One view is that some of these are the most asymmetric assets in the market: technology is available, valuations are extremely low, teams are active, and expectations are near zero. A token that is down 99% from its all-time high does not need a new bull market to double; it just needs a credible reason to pay attention again.

There is also another view that a token that has failed to recover its highs in two full cycles is telling you something that is not on the roadmap. The network can survive indefinitely, but its tokens don't improve; even if GitHub is still active, dead money is still dead money.

What can change the situation is not cooperation announcements or brand name changes. Instead, it is actual usage that is measurable, repeatable, and incurs costs, and these usage must be transferred through the token. Before any of the five projects demonstrates this, the chart is the most honest summary.
