thanks for your good share.
it's not illegal but non-registered fore brokers is often just a scam so you are better to find a trusted broker to trade with so your money is saved with them. The market is popular so you need to identify and avoid scam brokers so you can make a profit and not loosing all your hard earn money for nothing.
One of the most common complaints targeted at unregulated forex brokers is that they hit their own stop-loss targets when other brokers claim the target was not reached. This can be disastrous. Stop-loss targets, as the name suggests, are a safety measure put in place to protect you from excessive losses. This is simply unacceptable from a professional trader’s point of view.
Another less common but far more egregious complaint is that unethical, unregulated brokers move their own currency prices so that the loss limit is reached. They do this even when the market prices may not have fluctuated to that extent. These actions can certainly be described as fraud, but your recourse options are too limited to be worth consideration.
