3 Warning Signs That It's Time to Sell Cardano

Few investments age gracefully when the world around them speeds up. The same pressure applies in crypto. Builders, investors, and users do not wait politely for laggards to catch up; they migrate to speed, liquidity, and, most of all, excitement.

That reality now confronts Cardano (CRYPTO: ADA), which was once celebrated for its emphasis on peer-reviewed research to advance its underlying technology, as well as for its deliberate pace of technical progress. Three red flags, in particular, suggest that the project risks permanent middle-of-the-pack status unless something changes quickly. Let's check out each of these warning signs in detail.

1. Rivals are racing ahead in every dimension

In the crypto world, developers are the lifeblood of a blockchain.

They build decentralized apps (dApps), protocols, and tools that generate utility, liquidity, and real-world adoption. A thriving developer ecosystem attracts users, capital, and other partners, creating a virtuous cycle that drives a chain's value and growth. Without them, even the most technically sound chain can remain a ghost town.

In terms of developer activity in Cardano's ecosystem, it doesn't hold up very well against its chief competitors, Ethereum and Solana. Per Cryptometheus, a cryptocurrency data provider, Solana had 499 active developers, and Cardano had just 175 developers pushing updates for the week, down 33% from three months ago.

Furthermore, developers flow toward concentrations of capital, and that capital is pooling elsewhere. Fidelity, a major asset manager, filed in March to list a Solana exchange-traded fund (ETF). Bloomberg now pegs the approval odds of that ETF at 90% for 2025, which would be an institutional seal of approval that no Cardano product enjoys.

Meanwhile, Solana's total value locked (TVL) on its chain was nearly $12 billion in January and currently rests at around $8.6 billion. Cardano's TVL is just $331.6 million, down from $680.8 million in early December 2024. That means there's less real money parked on its chain.

And when builders, money, and regulators all prefer the other options, it's a big problem.

2. New upgrades aren't getting used

Blockchains tend to have technical constraints. Sometimes, those constraints are troublesome enough for users that the main engineers of the chain create big new modules or other solutions in an attempt to prevent the flight of disaffected investors, users, or ecosystem developers. The success or failure of those solutions is, thus, often a major factor in determining whether to invest in the chain's native token.

And in Cardano's case, the record with successfully developing workarounds to the chain's issues isn't great, at least not in recent times.

Cardano's Layer-2 (L2) system, Hydra, dazzled testers with a 1 million transactions-per-second (TPS) demo last December, implicitly promising to solve the issue of lethargic transaction times during periods of peak load. L2s like Hydra are designed to handle transactions off the main blockchain, reducing congestion and perhaps also fees while maintaining security and interoperability. But they only matter if users adopt them and volume grows. Otherwise, they're tech demos, not adoption drivers.

Five months after launch, no major exchange, payment processor, or other project has committed to using Hydra beyond a pilot.

Another solution, called Midnight, is a side chain, which means it's a parallel network intended for specialized features such as privacy, among others. Side chains can extend a blockchain's functionality by providing specialized services that don't burden the main chain. Midnight aims to attract institutional users who want confidential holding of assets on the chain, but so far, no major financial players have signed on, and no real user base exists.

These technical marvels might eventually matter. But until developers, institutions, or users adopt them, they remain tantalizing but empty promises. And that's a big warning sign that Cardano is failing to match its development of capabilities to the features that are actually in demand.

3. Cardano's mindshare is eroding, not expanding

Crypto is a popularity contest masquerading as a set of technologies.

On June 4, Cardano counted around 23,273 daily active addresses, whereas Solana cleared nearly 5 million in the same day. That gap widens whenever meme coin mania or non-fungible token (NFT) drops spark traffic spikes. Those are segments where Cardano barely registers, as its ecosystem is very sparse in both areas.

Social chatter mirrors the numbers. Per data from Santiment, a crypto data aggregator, Cardano ranks far below Ethereum and Solana in terms of social media post volume, hinting that investor excitement has simply remained elsewhere. If users, developers, and institutions are not talking about Cardano now, why would they flock to it later?

In other words, Cardano's investment thesis -- that academic rigor in the tech development process will eventually lead to late-bloomer dominance -- faces mounting counter-evidence. Unless Hydra suddenly wins real traffic or Midnight lands marquee clients, the token's upside may remain capped while the opportunity cost mounts. And there's just not much evidence to suggest that's happening, nor is there any reason to believe it will soon.
