Bitcoin is decentralized in nature and we can't deny that but we are talking about crypto in general where many of these new projects has already been controlled by whales, they are now manipulating the market trend, volume, and also the news. Maybe, for now, we can just say that crypto is still decentralized but sooner or later, as there is a massive growth of manipulations, this will change the system, and become centralized.
Objections are somehow useless, whales will take control of the market while investors will just ride the trend and hypes.
The manipulation by whales on the big projects is still understandable. I mean it is their money and they are risking their own money to control something which is totally understandable and that's okay. However, the project creators end up doing something that is a bit more shady these days by making it heavily centralized.
I mean look at Avax right now, could you say Emin has no say in it? Dude is basically "owner" of avax, or look at SOL, everyone loves it, and then you look at it and see they can freeze the network whenever they want. So all in all I would have say that it is not really as cool as you may imagine, it is quite centralized these days.
