I often hear people quoting that some country (most of the times China) is positive towards blockchain and are thinking to using it in their country, so they are also positive towards Bitcoin.
This is just a myth. To be honest Bitcoin and Blockchain are separable. Blockchain can sustain without crypto but crypto cannot without blockchain.
In recent times Bitcoin moved from 7k range to more than 10k may be with the news of China president talking about blockchain. Then people were saying that China is positive towards crypto but things were not that good. And now things are on the same page again.
So burst this myth that where blockchain is Bitcoin will also be there.
Everyone knows this. But traders like to move the price on "news" and sometimes fake news is concocted to try to move the market and persuade newbies to buy.
Also - there are keyword trading bots that automatically buy when the words "china likes bitcoin" appears in the news. They also sell when "china bans bitcoin" appears in the news.
