The most significant disadvantage of mBank is that it is not a regulated broker and does not offer the necessary trading features required by active traders. It lacks the ability to trade Forex, CFDs, or other financial instruments on platforms like MT4 or MT5. Additionally, mBank does not offer a demo account or swap-free accounts, which can be a major drawback for traders seeking to test their strategies or those looking for faith-based compliant trading options. For someone like me, who is looking for an active trading experience with robust features and regulatory oversight, mBank would not be the ideal choice. However, for those seeking straightforward banking and investment services, mBank offers solid options.
