I have been earning a living using Pay for Click advertising for over 10 years.
More recently I have been involved in Blockchain and Crypto currencies trends for 3 years.
However any aspirations of combining the two have taken another knock back.
Bing have followed the other major PPC search engines and plan to ban crypto related adverts by July 2018.
Therefore if your business is being affected by this squeeze on potential advertising options consider switching to Inbound Marketing and real engagement with people.
I am now using MarketHive why not get a FREE account and have a look around.
