Hello Gunthar,
interested to buy your bot for poloniex, is it still available?

Yes, those discount codes are still valid. Send a PM to Gunthar by clicking this link: https://bitcointalk.org/index.php?action=pm;sa=send;u=817682. Just tell him that you want to use a specific code with your purchase, e.g. mine: "GrumpyKitty".

I have a VPS server, Ubuntu 14 and 16, is it possible to get linux version?
