What are altcoins?

Altcoins, or alternatives to Bitcoin, are cryptocurrencies that emerged after the success of BTC. They represent a wide range of projects with different purposes, from technical improvements to specific applications in sectors such as decentralized finance (DeFi), smart contracts and digital governance.

In 2026, the altcoins market continues to evolve, with projects like Cardano, Solana and various meme tokens gaining prominence.These currencies not only offer diversification but also technological innovation and unique use cases.
