This is not the real price because mainnet has not been in process which is confirmed by PI devolpers. All these exchanges listed PI coins is called (IOU) which means that no deposit and withdraw possible and holder will get token with 1:1 exchange rate when it goes live. Remember that Arbitrum IOU rare was 16$ before launch but after launch price was low than 2$..

Now the PI unofficial market rate is below than 0.3$. If its trading was possible then you would not make a thread here. anyway it's on you but if you want this rate then wait for official listing which is seem to be not happen in short time.
