Salty or UnSalty?

For making cannabutter does it matter if its Salted butter, or unsalted? I'm aware the fat content is the important part.
Just wondering if there was a specific reason why most people use Unsalted

Cheers

use unsalted, that way you can use it for all types of cooking not just savory. it probably wont make much difference anyway, I'm sure if you make a cake/cookies with salted butter the sugar will mask the salt. many sweet recipes call for some salt to be added anyway.
