The price of course is what somebody is willing to pay. Nobody here however mentioned "the content". If you have an original and not spoiled content ( and a lots of ) it will bring a much higher price then some recycled garbage site ( tubes,blogs,and other social media) or the flavor of the month site ( VR,dating,pharma,cams,bitcoin etc..)
The price for a car dealership which only has a building and a bit of a name is entirely different then for the same dealership with 100 brand new cars all paid for and sitting on the lot.
So for such a site 24 month revenue seems about right PLUS an independent valuation of the content.
