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.
