The bitcoin marketcap is currently around $ 200 billion, and if we want to control the price we must have more than $ 100 billion, and I do not think there's anyone who has $ 100 billion so I'm sure no one can manipulate the price.
Yup, I do think so. The price of bitcoin cannot be easily controlled. The price is created by the community and it requires a huge amount of money to stabilize the price of bitcoin. Therefore, we can say that there is no way to control its price
