Is it really necessary to take a course before getting into trading?
It's not about the course but yes learning basic skills are mandatory which is also a key factor for trading. No work can be done if you are not having sufficient basic knowledge. It would be as same as you have bought a new car but don't know how to drive it, but yet if you try to drive it you may have to face great damage and loss of your vehicle. The same goes for trading. If you haven't acquired the basic knowledge of trading you might have to face a great loss and disappointment. Also start with a little investment, as it may reduce the chances of loss.
Yes I agree, learning about crypto and trading basically are the basic things before we enter to trading crypto industry. And we can learn it from many source. Not always to take a course. But if we are going to take a course in trusted course of course, it will be also helpful moreover if we are from basic enough.
But we must also set our mind about trading, that is trading will not always give or earn us money, it will also give us risks that we must face and also we try to avoid even this may be very difficult.
