Well obviously i don't think that this will affect bitcoin in particularity, all the ads that face book and google have banned, are ads for ICO and tokens, they haven't banned bitcoin ads because they don't exist, up until now bitcoin made it  all the way to 10k without relaying too much about advertisement, in my opinion this actually might boost the bitcoin prices and investments, because as i said all the banned ads are related to ICO, and they are the reason why we are not seeing usual investments into bitcoin, and with them gone all the money will go into the bitcoin market.
