The Forex Market is Risky! It is unlike anything else in the financial world because of its speed, volatility, and enormous size. Currency markets are highly speculative and volatile in nature. Any currency can become very expensive or very cheap in relation to other currencies in a matter of days, hours, or sometimes, in minutes. This unpredictable nature of the currency market is what attracts so many investors to trade. However, you have to first ask yourself how much you can afford to lose before you start trading.
