$IOTX old coins are surging?

$IOTX (IoTeX) Introduction
IoTeX is a blockchain project founded in 2017 by Raullen Chai, Qevan Guo, Jing Sun, and others. It focuses on combining the Internet of Things (IoT) with blockchain, emphasizing privacy and the trustworthiness of device data. In 2018, it raised funds via private placement; in 2019, its mainnet went live, using the Roll-DPoS consensus mechanism and EVM compatibility. It later evolved toward MachineFi and DePIN, and then focused on infrastructure for “real-world AI,” including ioID device identity, W3bstream, Quicksilver, and more—along with collaborations such as Vodafone.
