Never run these before, I'm running this for grey market.

Is it best I buy accounts from these guys on BHW and then run? I'm just really confused and want advice haha. Will this effect my SEO if the google add account gets banned ? In High volume niches will it be very expensive to get clicks ? And most importantly, is it worth it !

Having an aged account or billing account is always better than a freshly created account. so go take a look into the marketplace section and find the seller as per your requirements.
