Google end ban on cryptocurrency ads

Google is reversing its ban on cryptocurrency advertising this October. The American tech giant's ban on all cryptocurrency ads was first announced in March this year but came into effect this June in an effort to protect consumers from scam initial coin offerings and trading advice.

Google's new policy, which mirrors that of Facebook earlier this year, allows for advertisers from all over the world but requires individual certification for running crypto ads in Japan and the United States.

Facebook returned its cryptocurrency ads but with a special verification process as well. Aside from the tech duo, social networking giant Twitter banned the advertising of cryptocurrencies on its platform as well, with a complete ban on initial coin offerings (ICOs) and token sales while cryptocurrency exchanges and wallets were restricted only to companies that are listed on major stock markets.

Argentina hit with Protests

A 24-hour strike hit Argentina as the country is expected to introduce austerity measures in order to receive financial aid from the International Monetary Fund (IMF). Furthermore, the president of the Argentine central bank Luis Caputo resigned earlier citing personal reasons. It was announced he will be replaced by the former Economic Policy Secretary Guido Sandleris.

In order to combat the decline of the peso, the government of President Mauricio Macri negotiated a $50 billion standby deal with the IMF. On Monday, Macri said that he was in talks with the financial institution to extend the credit line for a further $3-5 billion.

The second-biggest South American economy has been experiencing a crisis which has seen the dollar rise 108.72% versus the Argentine peer since the beginning of the year.
