I am convinced that scalping is pretty risky, however all types of trading activity implies risks. It doesn't depend on the type actually. Whether you open short-term positions and lose them, or you will open long-term positions and you will lose them. The matter here is the time, if we speak about scalping then you will either gain money much faster or lose it, or if we speak about investing then you will open lots of positions and within a month you will either lose them or win them. Here everything depends on the quality of your analysis. To my mind, scalping is a true art and it's very difficult to be a good scalper.
