Thank you for the answers.
I'm using bread, but I want to put it on my site as payment option and It needs to be the same address as I can't change it live. That's why I asked.
Thanks again
Regards
If the only purpose of that address you are referring is to act as payment option address on your website then it's fine to do so.
Just used different addresses for other purposes
e.g direct personal transactions or other services you will offer with payment. Not just for privacy reason but for you to have a properly sorted out address for different uses.
In that way, there are no mixed transactions for different purposes on a single address and you can easily track past transactions if necessary.
