Hello Gunthar,
I have bought one of the very first versions of your Gunbot - back in 2017 - on the bitcointalk.org forum.
I would like to start trading again. Would it be possible to issue me a license? How it works nowadays? I have installed v20 of Gunbot - added my Bittrex API key (newly generated) - but the bot needs an ETH address associated with ERC20 tokes.
I have bought one exchange version back then. I am OK with it - I would like to use only one API = Bittrex and try your bot again.
Thank you in advance and have a great day.
