$ADA
The currency $ADA is the digital currency of the Cardano network, used for paying fees, executing smart contracts, and voting on governance proposals within the network. $ADA is characterized by its reliance on a proof-of-stake (PoS) mechanism, making it more energy-efficient compared to other currencies like Bitcoin. Some see it as a long-term investment due to the Cardano project's focus on scientific and technical expansion. It is listed on most major platforms and has a supportive and active community. Despite the volatility of its price, it still maintains a strong position in the market. Actual usage and future adoption will determine its success in the digital currency ecosystem.
