I think maybe it could be up to $ 1 million to be able to affect the price in the market
Lol! What is $ 1 million? For you it is a lot but any exchange sells several thousand bitcoins every day. In order to manipulate the price of bitcoin you need to invest a lot of money in fake news in the media. Then you need to capture the dominance of all the most popular cryptocurrency exchanges. I think this amount is several billion dollars.
