Could China (or similar) take control of Bitcoin? And my answer is Yes everyone can control of bitcoin if they had enough money and enough resources
And if you talk about a country it definitely can do that, 51% attack is doable right? And then if you want to do price manipulation you can buy as much as bitcoin and then can be act as a whale. Tho this is just my opinion guys
I guess China has all the chances to control bitcoin if they really aim to. Simply because they hold more than 50% of bitcoin and certainly act as a big whale that will take control the movement of bitcoin. Same like India and US that hold more than 50% amount of bitcoin, they can also take control bitcoin if they really want to.
