#PI Pi coin is currently still in the testing phase, has not officially launched on the Mainnet, and is not available for trading on any mainstream exchange. The Pi coin trading pairs listed on Gate exchange have not been officially recognized by Pi Network. Moreover, exchanges usually do not actively "kill off" a certain Digital Money; their main responsibility is to provide a trading platform and related services. As long as the coin meets the exchange's rules and regulatory requirements, and there is a certain market demand, it can be traded on the exchange.
