I am also wondering that Pi Network was already been here since 2 to 3 years ago but it still not listed on any small or big exchange platform in the market and the only making the value of Pi coins are the community supporters which they do it on peer to peer method. Though they say that's illegal to buy and sell pi coins because it is against the written rules on whitepaper. I think we should thanks the community for giving the coin a value now though it's not that high as much as the Pi believes that it values as 300$ each per coin.
