Is it because rich people have so much money that trade should be reserved for them. So what if they always experience losses, will they be able to survive in the trade? Trading is not intended for anyone and trading can be done by anyone who dares to take risks because the most important thing is how people can deal with pressure and they continue to try to correct the trading mistakes they make so as not to result in losses every time.
Trading is more effective when people have knowledge and money to start with. But not having a lot of money doesn't mean people can't get involved in trading, because you or anyone can use small capital to start, as long as you know how to trade correctly and appropriately.
I would highly recommend starting trading with small money because having a lot of money in no way guarantees, that you will be able to earn more, in fact it will only increase the chances of losing more. But there is no need to take my words as a warning against trading with big money, both rich and poor can lose everything, just as rich and poor can earn, this largely depends on knowledge and understanding of the market and its manipulability, and not on the amount of money.
