Market manipulation is an attempt by a certain market player to predict the behavior of other market players in response to various options of their own behavior. They bet money that their prediction is true, and that a certain market behavior will bring them profit at the expense of other players’ losses—and then they test their prediction.
Formally, there is no violation of the non-aggression principle here, but if the manipulator’s prediction turns out to be correct, other players suffer a loss, and they, after all, did not enter the market for that purpose. Therefore, it is not surprising that the manipulator may be disliked.
Most market participants prefer predictability and do not highly value a store where, as a result of manipulations, the price jumps randomly. Therefore, the store is interested in introducing its own restrictions that make manipulation more difficult, and the smaller the market size, the more relevant such things are for the owners of trading platforms.
Insider trading is the same kind of market manipulation, except that the manipulation is carried out by the trading platform itself or persons affiliated with it. Naturally, for the reputation of a trading platform, being caught in insider trading is even more dangerous than if it allows manipulations by third parties. Therefore, in developed markets, insider trading is fought even more strictly.
And the state, when attempting to fight these things, as is its habit, either simply tends to make a mess with the best of intentions because it doesn’t know how to be efficient—or, under the pretext of fighting manipulations and insider trading, engages in those very manipulations and insider trading.
Now, in cryptocurrency trading, there are as many market manipulations as you like, but the higher the turnover, the less dangerous it is for those who do not suffer from it. So choose Bitcoin; it is the least prone to manipulation of all cryptos. I have chosen it specifically as the currency for receiving your kind donations: 1A7Wu2enQNRETLXDNpQEufcbJybtM1VHZ8
