Seeing big companies buying billions+ dollars of bitcoin, isn't it becoming too centralized. Could they centralize it if they own a lot of it's portion.
How can we defend against this process?
Yes, it is getting centralized and I'm afraid that there isn't much that we can do. They are even buying Bitcoin at 100K USD while most of the people are selling at this price. They are here for a long-term plan while many people are here for short-term gains. They are buying millions of Bitcoins and are concentrating a large portion of Bitcoin in their hands. With this, they can move the market and manipulate the price to make more money.
Trump wants to mine the rest of the Bitcoins in the United States, which will make it more centralized but I'm sure that this was another populistic statement from him and it won't happen in reality.
