Seeing as how important and topical bitcoin and crypto advertisements are nowadays, it wouldn't make sense for google to continue its ban since they will be losing hefty revenue from potential advertisers and customers. That being said this lift will cause more scammers to come in and take advantage of poor people's moneys so it's our job as enthusiast to prepare ourselves
Scammers would always hop into anything that has a potential to ease their activities so I will not be that surprised to see them do the same with good ads now that Google allows it on their platform. But I believe that by now, people in crypto should be well informed now abi the various ways a scammer can try to scam them. Google announcements is good news though. It means exchanges can advertise and bring more users in. More volume, liquidity and cash inflow into crypto just in time for next ride to all time high.
What Google did by lifting the ban on crypto ads is news we should all welcome. Because this should be good news that can make the crypto
world develop even better. But negative effects are also bound to occur, such as scammers will return to action again. But as you said scammers
will always be around, so don't worry too much about it. Especially now that the crypto community has been educating everywhere about crypto,
I believe the percentage of the number of victims of scam in the crypto world should decrease.
