Pi chainmall is one of the best platform to do this, but its not launched yet because we are still in the enclosed mainnet of the pi project. You can still exchange your pi coins for fiat or other cryptocurrencies, by selling your coins to a Verified merchant/vendor. A vendor is basically someone who buys pi network coins from miners like you and resell them to investors looking forward to hold up to 50k coins before mainnet launch in 2026. I will leave the what'sapp contact of my personal pi merchant to trade with. +12349014282 Thanks for reading 🙏
