What happend today - I do not guarantee this is 100 % correct - however this is what my twitter research tells me:
1: DDoS Attack on exchanges in China - exchanges shut down to save users.
2: Finance blogs use this to spread fake news: in 2017 you earn a lot of money with spreading fake news as many people come and read them. However this fake news is from a Plattform that is trusted in the crypto world as far as people tell me:
3: Finance investor with a lot of followers - who has a lot of great tweets - that is to say at this point - reposts that he predicted a 2nd crash. And reading his other tweets tweets we know he sold most of his portfolio and will go in BTC < 3500 (or > 5000). However - tweeting this at this particular point fears the people following him a lot.
4: a really good Bloomberg tech reporter from china says at first that the exchanges will be shot down, in a second posting she says that the exchanges did not get an information from Chinese gov. In her newest posting she spreads again some uncertainty.
5: exchanges say that they are up again and everything is fine.
Crypto gods like Charlie Lee retweet:
6: crypto community is discussing:
7: and start to comment on those platforms that spread the fake news:
8: and this is how the charts look like. I guess we are fine again in 24 hrs.
Edit: the ban is on ico and crypto as insurance:

Edit #2: and now classic media start to talk about the fake news - unreflected and without any further research by themselves.
