I think China is just a top of iceberg.
There is very strong lobby of bankers and brokers. In most countries below articles about bitcoin you can read super long list of comments that bitcoin is not real, it is bubble, it is worthless. If you will ask your advisor - he will tell you not to invest in cryptocurriences, banks are forcing banning of cryptocurriencies. They will loose huge amounts of money.
Simple example: what would you choose: 2 days upto 2 weeks expensive unconfirmed (you dont know if someone didnt sent or bank is playing with your money) international money transfer, or super fast, cheap and confirmed crypto transfer?
So last week we have seen:
1. Putin forced by lobby trying to ban people from crypto trading, only professional brokers will be able to do that.
2. China in panic bans ICO's, now they are realising this decision was too fast and too stupid
3. Many articles, written even by noble prize winners, that it is huge bubble and worthless
4. A lot of articles about huge dumps of BTC, generating panic
We are at the edge of economic war.
Countries like China and Russia fear capital flight, that's why they're cracking down.
Regarding the articles about bitcoin falling - a week ago they were writing excitedly about bitcoin rising - it's just journalists doing what journalists do. Nothing to worry about.
