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.
Hindi naman talaga ang bitcoin ang inalis nila e, kung hindi, yung mga advertisement tungkol sa isang ICO at mga trading sites. Ito kasi ang mga source ng scam kaya inisip din ng Google na ayaw madawit sa ganitong kalakaran. Kahit ngayon may mga nakikita pa kong ads tungkol sa bitcoin at iba pang crypto.
