I don't blame @hbdstabilizer, I understand now the cause of my loss. @quicktrades is a dumb market maker bot that was successful on both blockchains before. I have now to change my strategy and knowing how your bot works should make the change easier, but I'm lazy.
@hbdstabilizer is a good idea to lower the price of the stablecoin while conversions work the other way. Your project is good and I could support it after starting to earn again.
