It is called binary option. You can do it if you want but I will say it is not safe at all. This can make you a victim of a lot of scams. First of all, you will not find a trustworthy broker. Again, even if you get a broker, there is no guarantee that you will be able to exchange. Because almost all exchangers here are scammers. It has high risk. I would say it is better not to engage in it. But it all depends on your personal opinion.
It is also better that a person invests in a place where he can benefit first of all choose a good exchange so that he is not taking the name of this exchange run and that exchange has been working for years like Binanc. It is a very great exchange I am using it myself also a broker for myself there are good brokers not only those who are scammers there are also good brokers take help from them In the beginning, once you learn up, then do not take help from them, but until you learn, you will need a lot of help, because without learning and without understanding, you can never do up trading, you will only do your own loss, so avoid this loss. So we have to search for a good exchange first and also good broker.
