Hello, of course, you can’t remember all types of trading at once, but I can assume that this is most likely binary options trading, because, in this type of trading, the trader’s task is to analyze and predict the direction of the asset. Assets are currency pairs, indices, raw materials and metals, and cryptocurrency. If the trader's prediction turned out to be correct, he will return his investment and receive additional income. If the trader made a mistake, he loses the amount of the transaction, if you are in doubt, then visit that site, this is a broker with which you can register and understand whether your friend uses this type of trading! |
