Currently few Bitcoin whales are controlling and manipulating Bitcoin price.
There is a huge difference between manipulating the market and having control over the price.
Nobody can control the price, that requires centralization and a limitless amount of money to control bitcoin price. You may be confusing bitcoin with a shitcoin here.
Manipulation on the other hand is possible, as it is possible in any other market in the world. It is a little easier in bitcoin market because it is a smaller market than most established century old markets!
Every individual must be able to buy and sale bitcoin from the person and to the person.
Individuals shouldn't have to buy or sell bitcoin, instead they should be able to earn bitcoin and spend it like they do any other fiat currency. After all they don't "buy fiat"...
