The main IPBC exchange
https://livecoin.net/?from=Livecoin-PjNuy7zS does not have ops working on the weekend. So while you can deposit or withdraw bitcoin and trade IPBC, you can not withdraw or deposit IPBC till they get back tomorrow and update the wallet, as it is behind since 23000.
Trading is not working also (at least for me). I can't buy or sell IPBC on livecoin: requested order cannot be placed.
However I see new trade history and orders are submitted from other users, maybe trough API works.
