FB payment method

Hey guys,

So I've created a new FB advertising account and want to add payment option.

I have 3 options:
cc
paypal
and bank account

I am doing WH, but still want to make sure my ad accounts are not linked together.

Just received a new cc, but with a limit of 500 a month as of now. (mucho time to get it removed). So I've found I can add my bank account as a payment or other alternative would be paypal ( so I can add additional cc-s). Not sure if they would be linked together if I have another ad account with the paypal credit card already added.

What do you think?
I probably will go with the bank account- there also should be no fees as well. Also, FB didn't offer this option in the past...

Don't add Same Paypal, CC or Bank Account that is already link on other ad account. Try to attach fresh cc or Bank account. Its safe

Thanks. so just to clarify:
1 have another add account and another cc. that is all FB has from me besides name and IP address I guess.
that cc is added to Paypal, but Paypal is not added to that Ad account.
