The same country with the word P! ProEX publicly supports the Exchange of Pi Currency:

"In order to support the decentralization of the blockchain, the ProEX cryptocurrency international exchange from Singapore announced that it will review the listing of Pi coins as soon as the main network of #pinetwork is officially launched. At present, Pi Network has started to operate the closed main network independently, but the closed main network is not the real main network, and the blockchain will not be launched until the real main network is launched"..
