BIP44: What's the use of internal addresses? 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!
The separation between internal and external addresses comes from BIP32.

Using a different chain for each permits you to give out an xpub for just the external ones to an auditor. They would then be able to observe your incoming payments, but not your spending.
