Stir in foreign exchange, transfer funds to the company, and pay dividends every month. Is it safe to say that the funds are guaranteed?

Not safe. Foreign exchange speculation is an independent transaction and is responsible for its own profits and losses. Even if investors transfer money to the company and pay dividends every month, the company can't guarantee investors' income. When the company promises that the funds are safe and secure, it is not credible. At this time, the company is cheating investors, and the funds are not safe.
