These are the one's that we must avoid because they are not contributing anything in this space. They are only here for business, to make a profit and the only one that can profit the most is their creators, not the investors.
I think the OP should change the title from "Bitcoin is controlled" to the "Crypto market is controlled". After all, whales are the ones who move market prices in their favor. Not Blockchain networks themselves. Bitcoin is by far the most decentralized cryptocurrency in the world, especially now when most coins are switching to PoS. Exchanges can do whatever they want with PoS coins using customer funds, but the same cannot be said about Bitcoin. They need to control around 51% of the network hashrate to be able to "steer" Bitcoin in their own direction. And we all know that's impossible to achieve considering that lots of money will be spent in the process.
The community should keep Bitcoin decentralized to help ensure it lasts for generations. As long as it stays that way, we should have nothing to worry about. Who knows if 99% of altcoins die in the long run due to lack of decentralization and censorship-resistance? Just my thoughts
