The latest wave of policy changes at tech giant Google is about to hit the cryptocurrency sector—and skins gambling, too.

On Tuesday, Google announced that it is changing its advertising policyto target selected financial products and services. The updated policy, which will take effect in June, specifically bans advertisements for binary options and all cryptocurrency-related content, including initial coin offerings (ICOs), cryptocurrency exchanges, cryptocurrency wallets, and cryptocurrency trading advice.

The policy will also prohibit content advertising for “unregulated or speculative financial products,” which include financial spread betting as well as contracts for difference and rolling spot forex. Advertisers offering promotions for the listed products will have to secure a certification from Google before they can advertise via AdWords. The certification, according to the tech giant, is only available in select countries.

The limits placed on cryptocurrency-related promotions mirror that of the restrictions placed on ads that promote say, sexually explicit content or counterfeit items.
