What kind of people are capable of market manipulation?
To the best of my understanding, market manipulation can take place in a wide range of markets, from commodity, Forex to cryptocurrencies. It is not limited to any country or market type. However, the impact of market manipulation can vary widely depending on the specific context and regulatory environment in a particular location. It is generally perceived that individuals or entities with substantial financial resources, can leverage their financial clout to manipulate prices in their favor.
It is everywhere not only on those markets that you mentioned or financial market as a whole. It is not limited to one country but I believe any country has it, even if not on the same field (E.g in the financial market). Manipulation are a bad thing even if it's only small but a small one is better than the big one's because people can hardly feel it's effect.
A huge capital or money is mainly the root of these manipulations but we still can do something to prevent it. If only we won't be greedy and don't take the shady offers by these manipulators, they will not be successful with their attempts. Our lives will be much better this way. In term's of crypto market, many of us are not involved with it, like for example in Bitcoin manipulation but we are only riding it and we still can benefit with it.
