As Forex trading carries risk, losses are inevitable. Retail speculators are almost always trading undercapitalised and can be subject to the problems of gambling addiction and improper use of leverage. Any speculator who trades without skill is essentially gambling.
In all fairness, a large number of the reports of money being stolen by brokers is a result of weak trading, and not scam brokers.
Any trader, both experienced and novice, can become a victim of a scam in the Forex market. Before investing in a particular broker, be sure to read the honest broker reviews on the Global Fraud Protection website, this will help you avoid losing money.
