Even then how do you differentiate between the intentions of different orders? If you were under their thumb you'd simply say that spoofy order of yours was pulled because you suddenly had to pay for your uncle's sex change.
It's impossible. It's nothing more than a showoff to make clear they are guarding the market and operate strictly to protect you, the investor/trader. Standard bla bla that isn't worth anything. If they already can't properly watch/guard traditional markets, how will they ever be able to do that with the brutal crypto market?
The crypto market consists largely of retail traders, all with emotions overflowing. They gain zero benefit from taking actions against you. They are likely just preparing themselves for the institutions that are slowly but surely entering the market. In that regard they can monitor activity in a far better way, and in case they cross the line, the authorities can actually make them pay for it.
Result in the end is that whales toying around will become more creative and find less obvious ways to manipulate the market, but with the exact same effect.
