The cryptocurrency market is constantly seeking new growth opportunities. Ahead of 2026, three projects stand out for their potential and practical applications. Let’s explore why Sui Network, Cardano, and Sei Network attract the attention of experienced and conservative investors.

Sui Network: Innovations in Data Security

Sui (SUI) demonstrates steady development thanks to continuous updates from the Mysten Labs team. Currently, the token price is $1.80 with a market capitalization of $6.81B.

These innovations attract a growing ecosystem of developers, confirming the project’s long-term potential.

Current updates include the launch of Midnight and Glacier — initiatives that add privacy features and introduce new tokens into the ecosystem.

A stable network and active community support ensure steady development. Although ADA has shown a minimal growth of 0.02% over the past day, conservative investors value Cardano’s reliability as a long-term store of value.
