Don't be shocked, Mate. Because China always has an idea for Bitcoin.
You may see the latest bad news about China ban? And this country has been doing this for years ago.
It is not only about like or dislike crypto but it is about business, politics, and also other specific reasons.

And about those 150 BTC public nodes, just don't really take in mind. I know that it may make some people panic moreover with the China Ban news again. However, as what has been said by members above, the number is only a few amounts of the total nodes.

Once more, there will be always any FUID every time and don't take it very seriously that can lead you or other people to panic.
