Hold on...
Yup, I didn't travel back in time...
This indeed IS year 2016 - there are ever SO MANY guides to starting your own PBN, most of which all discusses prices etc. yet this is a brand new question posted today.
Stop polluting the forums with the same questions AGAIN and AGAIN.
I usually answer questions rather than asking questions, however in the odd event that I do ask a question it is certainly well researched.
Every time I do, however, they quickly drop down to page 2 before anyone has answered.
Guess why? Because of threads like these where people ask the same generic stupid questions over and over again.
(and yes, this is objectively a stupid question since the topic has been discussed countless of times during the recent years)
