Backpage.com is a website like Craigslist, although it is more scandalous and provocative. The site was well-known for allowing sex workers to post solicitations. In 2015, the site was alleged to be permitting prostitution and propping up a sex trafficking ring involving youths. These charges were never validated, but the fallout caused a shift in the way the peaceful sex industry uses money and does business. Bitcoin is now one of the main forms of currency fueling this enterprise. So how did this happen?
