Personally, I think that such a measure is temporary. Indeed, thanks to Google advertising gets a lot of money. This market is becoming increasingly popular and large-scale. Therefore, Goole is unlikely to give up this important market for a long time - it will soon restore work with reliable cryptocurrencies.
Google can't stop crypto, the crypto industry is growing very rapidly and advertising is the highest cost of a project, it is a big loss if Google bans ads related to crypto and now without advertising on Google, crypto continues to grow well.
