An even easier way to manipulate the price: make crypto illegal. Most people don’t want to do illegal things, therefore demand will drop and in turn the price will crash. In theory it’s all decentralised and everything but if people don’t use it for the fear of a jail time then it’s not much of a security. Just wait for crypto to become a big enough pain in the butt for the elites and you’ll see how quickly it’ll be done over with.
