Thoughts on that Bitcoin was created by a member of China. And that once there is over 60 % adoption in the world. Someone will push a button and it will ignite to something much more powerful and controlling>? more centralized?
Many people think like that, but there is no proof that it's true. Maybe China will able to make their product control the world, but I think it is hard to be true if they can build the Bitcoin ecosystem from the beginning and make it great like today. They can't control Bitcoin if ecosystem mining can be done anywhere, and they are even leaning to banned Bitcoin which I think is impossible for China to control if they forbade themselves.
