it has never been China! it was the news of China.
it has always been the market makers in bitcoin who manipulate the market to their own advantage. the news is just the icing on the cake which makes it easier. others also know this pattern and join in. for example when you hear a bullshit news like that and you know panic is about to break out, you dump as fast as possible because "cheap coins are on the way" and make a huge profit from idiots.
again this has nothing to do with China.
the chart you marked is mostly falls in the period where Chinese didn't even have access to any exchanges! their own exchanges such as OkCoin, Huobi,... were closed down for months and they could not trade on foreign exchanges.
again proving that swings has nothing to do with Chinese, but idiots who think it is Chinese so they fear when others are silently taking their money and blaming Chinese!
The chinese didn't need to have access to said markets. Bitcoin is exposed to the entire world, what im saying is, the panic selling gets triggered by news that come from China, im not saying it's the chinese dumping.
What I don't doubt is, the government and people with insider information foresee these press releases of "PBOC to regulate exchanges", "China banning ICOs"... and so on, so they can set shorts before the news are released and then profit from the dump. This is insider trading and this has been happening since the beginning of the first market to ever get established. It's obvious that Bitcoin's market is not going to be immune to that.
again it was not related to China, it was the "NEWS" from China or let me say
it was the news. and the news can very well come from anywhere in the world. it just happens that Chinese have been the focus of most news for some reason. otherwise it is the market that reacts to them.
don't you remember the ETF? or was that Chinese too?
my guess is that because it is mostly because of Chinese government and because it is a foreign language! for example if during ETF news someone said US banned bitcoin, everyone could easily check it with a fast google search and laugh at the lie (most people speak English and it is easy to find news that way) but if you say China banned bitcoin, a google search doesn't bring up anything unless you know Chinese and can verify the news. so the FUD is always like that: China banned bitcoin, Russia banned bitcoin,...
and here is the funny part:
you say "PBOC to regulate exchanges" i say regulations issued by the New York State Department of Financial Services for all crypto related businesses in effect for 25 months (2 years and 1 month) exactly.
i say IRS taking taxes, raiding people houses for tax evasion regarding bitcoin for 3 years
you say "China banning ICOs" i say SEC has already started issuing warning about ICO scams ever since July. and they have shut down a couple of them so far.
but the funny thing is nobody even hears the news from other parts of the world. China farts and the internet is filled with FUD that bitcoin is gonna die.
