How can I be sure that you will not stole my assets through your bot?
There is no way for any user to verify this unless the bot is open source and you know how to de-compile and check that. What you can do is check out any reviews on the internet even though they may be paid reviews but well known bots like GunBot have a reputable following and can be used safely. Newly released bots which do not have an open source code are always frowned upon. In short do your own research.
OP's trust page shows this:
This user's email address was changed recently.
This is suspicious though. This account was having gaps in posting history as well.
