Ordinary options are real securities that are held in a depository. They can be bought on the Moscow Exchange after concluding an agreement with a broker who has a license from the Central Bank. Binary options are just virtual bets. Their operators can work without a license and sometimes are not located in Russia at all. Often these are online platforms where only an email address is needed for registration - such transactions have no legal force. However, there are exceptions here: some licensed brokers carry out official transactions through American exchanges: there binary options are classified as securities.
