https://bitcointalk.org/index.php?topic=3133353.0Google doesn't really ban Bitcoin Ads since there is no Bitcoin ads at all. Bitcoin is not being advertised on Facebook or even on Google the reason why we don't need to panic. Google and Facebook banned ICOs, trading and exchange websites. The movement of the price of Bitcoin is normal even though it really takes a lot of time to pump.
I dont understand why they should do that to ban bitcoin in the google,but i dont think so it was happened because theres no valid reason the google to ban the bitcoin.I dont have enough idea but i just trying to share my opinion and i dont know to the others what there opinion and idea for this.
