TRX, or Tron (TRON), is a digital currency founded in 2017 by Justin Sun. It aims to create a decentralized ecosystem for sharing digital content, allowing users to publish and share content without the need for intermediaries like YouTube or Apple. TRX is used within the TRON network to pay fees and rewards, and it can also be used in decentralized applications (dApps). TRX is considered one of the active currencies in the market and is often used for fast and low-cost transfers. TRON is characterized by its transaction speed compared to other currencies, making it attractive to both users and developers.
