I've read other questions (and their answers) on this but I still don't see the use for internal addresses. I get that you're supposed to send the change of a transaction there but I don't see how this benefits you, all it does is move your remaining funds on an address, right? And you could just as easily move your funds to a new external address. I understand that the point is to use an address only once, but that can also be done with external addresses.
I hope that somebody can explain what benefits internal addresses have,
Thanks in advance!
