How to make money from FX?

I'm curious about how one can earn profits from Forex trading. Could you please explain the basic strategies or techniques involved? Are there any specific skills or knowledge that I should acquire first? Also, what are the risks involved in this type of trading? I've heard stories of people making huge profits, but I'm also aware of the potential losses. Could you give me a realistic perspective on the earning potential and risks associated with Forex trading?
