As you saw, on Twitch’s TOS they state this:
You may not sell or transfer Bits to other users of the Twitch Service, or offer Bits in exchange for real or virtual currencies or any other consideration or items of value whether inside or outside of the Twitch Service.
We have not gotten a reply back from Twitch, so no, we will not add this to PhantomBot. Could you edit the script and do it yourself? Yes. However we don’t recommend that, as you and your bot account could both get their channels terminated.
Have a nice day,
