China and its people are manipulating bitcoin. It's the nature of their culture. Secrecy and a few getting rich.
I think it is affecting now because the value trend for bitcoins this week are declining now and also the altcoins value are declining dramatically maybe because some people are easy to panic and they will easily to decide to sell their coins without confirming the news if is real or just a fake news but i believed this declining value will be temporary because the moment bitcoin value become lesser then many will grab this opportunity to buy bitcoin in huge amount at a cheaper price.
