the answer is obvious! a large amount of cryptocurrency advertising clogs the Internet and prevents ordinary users from easy and easy use of the Internet + google and facebook are closely connected with the authorities, and this directly affects their decisions about the cryptocurrency!

Not clear why facebook and google prohibit the news about cryptocurrensy, any negative news about cryptocurrncy usually bitcoin prices directly plummeted, what is indeed like this criptocurrency trip.

The reason is because their companies were being used by the advantage takers who are scammers. And this is why they are trying to ban crypto paid ads, they are not literally banning the whole concept of cryptocurrency but they want to ban the paid crypto ads because of these scams. Twitter ban is just a rumor and there's no update yet about it.

Yeah, this is kind of misleading news that cause people on panic. Well, all I can see in crypto ads is just a pure ICO and most of them are just a scam so better that thing to be shut off. One day, I know those big companies will finally use this kind of technology and who knows they might create their own token so for me don't panic about this news.

I think you can not compare market price reductions with other social media bans, because I think the advertising ban cryptocurrencies in social media is because so many bitcoin communities are bombarding crypto ads, and the account managers are a good destination for the security of their users.

Yeah China didn't fully banned crypto, there's no clear news about the said ban and AFAIK it's only the ICO's.

These two news made the market to crumble. There are many other reasons that we need to consider but these are the few ones.

If we look at the bright side, facebook and google banning cryptocurrency might bring better impression on cryptocurrencies, at least first impression. Since facebook and google have a lot of users, cryptocurrency's reputation have been jeopardized by spammers and scammers.

I think even useful ad like crypto trading exchanges that are also using them to advertise will be banned as well. I've seen many exchanges that are advertise through google and even in youtube.

This already gave bad impression for cryptocurrencies so there's no bright side that way. Maybe there are some but this isn't that side.

What exchanges are you referring to? I honestly haven't seen ANY legitimate looking service advertising through either Google or Youtube's platform. In most cases when I was just searching for blockchain or Bitmixer through Google, ads clearly being phishing sites popped up. Seriously, who needs these ads anyway? If you search on Google for Bitcoin exchanges, you'll see now actual Bitcoin exchanges pop up, and not phishing sites mimicking Coinbase or whatever. It's a welcome change in my opinion, and I wish they did it months ago already.

Popular Google search results popping up on top of the page now;

Bitcoin exchange; GDAX.com
Bitcoin wallet; a legit local online wallet service, but after that, in more mainstream terms, it's blockchain.info
Bitcoin investment; articles pop up instead of whatever shady investment platform promising you 10% weekly returns

In current times ICO ads are still being displayed, but that will change within a few months. I am at least happy that Google has implemented some changes, especially when it comes to blatant phishing sites. Their algorithm detects and gets rid of phishing sites much sooner, that's something I have noticed.
