March 14,2018:

Google will ban the online advertisements promoting Cryptocurrencies and initial coin offerings starting in June, part of a broader crackdown on the marketing of a new breed of high-risk financial products.

On Wednesday, Alphabet Inc.’s Google announced the decision in an update to its policy, which says it will begin to block ads for "cryptocurrencies and related content."

Facebook Inc. took a similar step in January, leaving two largest web-ad sellers out of reach of nascent digital-currency sector.

Bitcoin, the largest cryptocurrency by market value, pared an advance of about 2 % after Google’s announcement, trading little changed at $9,099 as of 1:04 p.m. in Hong Kong. Rival coins Ripple and Ether also pared gains.

Google is also restricting ads for the financial products including the binary options, a risky derivative with an all-or-nothing payoff. Right now, Google queries for terms like "binary options" and "buy bitcoin" produce four ads at the top of the results.

Facebook, Google’s primary rival for ad dollars, banned ads for cryptocurrencies in January. Some aggressive businesses found a loophole: purposely misspelling words like "bitcoin" in their adsounds like this.

Google’s updated policy came with release of its annual "Bad Ads" report, a review of the number of malicious, deceptive and controversial ads Google scrubs from its massive search, display and video network.

In 2017, Google said it removed more than 3.2 billion advertisements from the web. That’s up from 1.7 billion in 2016.

Last year, for instance, Google pulled 79 million ads for luring online clickers to websites with malware. Google is also accelerating a push against misleading content.

Company suspended 7,000 customer accounts for ads that impersonated a news article -- what Google calls "tabloid cloaking" -- and blocked more than 12,000 websites for copying information from other publications.
