I have a friend who is into trading, so he can make a lot of money in just a couple of hours, but he does not want to tell me, I understand this type of trading does not require additional knowledge, you bet on whether the price will rise or fall, please tell me , what is the name of this type of trading and what is needed in order to start trading in the same way?

Hello, most likely this is binary options trading, well, it looks very similar, because a binary option is a digital contract, the subject of which is the forecast of the direction of the price of an asset in a selected period if the forecast is not justified, the second party loses an amount equal to the value of the option, I'll tell you what, pay attention to eoption reviews, this is a broker you should register with to make sure if your friend uses this type of trading or not.
