"Twitter today confirmed that it too will be banning private ads for cryptocurrency sales and initial coin offerings. It joins Google, the world’s biggest online ad company, which announced earlier in March it would no longer show ads related to cryptocurrencies like bitcoin. That move followed Facebook’s January ban on cryptocurrency and ICO ads, joining Chinese web giants Alibaba, Baidu and Tencent, which haven’t allowed these kinds of ads for much longer.

That means companies like Coinbase or Gemini, which serve as marketplaces and exchanges for virtual currencies, and advertisers promoting an ICO or encouraging the purchase of a particular cryptocurrency, are effectively shut out of 70 percent of the world’s digital ad market."
