This sure sounds like the kind of thing which could cause a panic if true...
It's from China`s Central Bank. They did the announcement today.
Last week, they released other annoucement and they said that all the financial companies(banks, insurers, etc) must stop accepting any Bitcoin business(to open accounts and so on).
Today they came with same clarifications and they have banned third-party payment companies from doing business with bitcoin exchanges
"For payment companies that have already done business with Bitcoin Exchanges, should end their business cooperation; withdrawals of balances should be completed before the Chinese Spring Festival (January 2014), and new payment services are not allowed"
That means all the exchangers from China(BTC China is the biggest one) must close the business as soon as possible.
At this time, BTC China does not accept deposits anymore.
So, China banned Bitcoin for good. China transactions were more than 50% from all the Bitcoin transactions
The price will go down fast. It's already $650
