Google has allowed crypto ads related to wallets and exchange platforms to be displayed globally starting from August 3 of this year. Though the crypto wallets and exchanges should be based in US for time being. ICOs and DeFi are still not allowed to place ads in Google's advertising network. This is a good move because there are many scams taking place with respect to crypto coin ICOs , and Facebook has actually allowed advertising of these crypto scams which is not good for crypto community. Google has done right by setting up limitations and allowing only crypto wallet ads as the popularity of cryptocurrency worldwide is always increasing.
