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?
60% adoption in the world is from China, is it real? Honestly I don't think this figure is correct.
In the past, majority of Bitcoin miners concentrated and located their mining farms in China mainland. After China attack against Bitcoin mining, there was a big migration to other nations like the USA., Kazakhstan ... that contributed to make Bitcoin network more decentralized.
Nowadays, China mainland does no longer have 60% of Bitcoin total hash rate. I am sure 60% is not a correct figure from China mainland.
