Butcoin takes trust away from governments and bankers and puts it in the hands of crypto exchanges, that print fake dollars (Tether) to buy Bitcoin and raise its price. Nice transition.
You're clearly misunderstanding what bitcoin is about. No trust is put into crypto exchanges. Trust is put into cryptography, which miners help with. This kind of puts the trust in miners, but in order to do anything as a miner, you'd need to either break sha256, or you'd need 51% of the computing power. The latter is more likely, but it would make bitcoin useless because people will lose trust in the system, thus anything you'd do with the money you'd steal/double spend would be worthless.
On the other hand, individuals can still put their trust in crypto exchanges, but unlike the old system, you are not required to put your trust in an exchange.
What makes you say exchanges rule Bitcoin's world? If exchanges are the equivalent of banks, miners are the equivalent of governments. So if anyone "rules" "the" Bitcoin's world, then it would be miners. Not exchanges.
