Google ads for Bitcoin are not bad. Every business in the world needs publicity,advertisement to project it. So ads on Google about bitcoin are good. Because Google is a big source of publicity today.
The publicity and advertisement will increase the value and worth of Bitcoin.
I have to disagree with everything that you've said! Most of the
BTCitcoin related Google ads, together with a certain registrar
[cough (Name)... cough (Cheap)] that doesn't care to clean up their mess, are the sole reasons that hundreds/thousands of scammers were able to achieve their main objective in the past few years and in regards to the subject field of this thread, despite what they were claiming in the past few years, they never really stopped such ads from appearing in their system!
That will be helpful to introduce bitcoin to the people.
But it's definitely the worst way of introducing
BTCitcoin to newcomers!
