I agree with you, before starting an investment, it is better to first gain good knowledge about the subject and then make an investment decision. There are many new investors who invest without knowing or understanding anything about where they are investing, only hoping to make quick money, as a result of which they are being cheated. New investors fall into the trap of fraudsters without being aware of themselves and due to greed. New investors only think about making money and do not think about the loss and their greed is responsible for this. Before starting an investment somewhere, it is better to take time and research it thoroughly and use the money that you can afford to lose without using the necessary money.
I trade carefully because things have blown out of proportion in the system, gone are those days where you can trade carefully without any fear but as time goes on, the market become populated with traffic and introduction of scams enters the market. These scammers are the villains and they're able and capable of scamming us from our hard earn money made from trading and investment, I'm not ready for that drama.
Knowledge is power and without it, most people wouldn't be able to handle the pressure they comes with trading and other stuffs. It's always recommendeable to know the basis of the market before diving all in because the market have been really a space where losses and profits are made and in everything you do, always ensure you're on the winning side because none of us would afford to record losses especially on a streak, definitely not going to happen.
