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.
Yeah, your statement is right about bitcoin and blockchain that both of them are different things. Where bitcoin is a digital currency that runs on the blockchain while blockchain is a digital data storage system.
Why do people always assume when the blockchain is raised that bitcoin will rise? well that's because bitcoin is the currency that popularized this blockchain technology. So fundamentally they will think like that.
