Do you drive a car on road directly without learning how to drive? No right? Similar case with trading also. If you trade without proper knowledge then, you won’t get any profits. Trading takes lot of patience and dedication. Hence, if you want to make profit in the trading market as a beginner, then you need to master the art of patience. Try learning the theoretical things first, then do trading on demo balance. At last trade with the amount that you can really afford to lose.
Yes, this is carelessness that should be avoided because after all trading is an activity that can be very risky when you treat it in the wrong way, understanding and knowledge are always very important because this will be the basis for the decisions we will make later, and if for example, you come with the intention and purpose of making a profit while on the other hand you don't know at all how to trade and what things have to be done, then yes, it's clear as you say, which is the same as driving a car without knowing how to drive it, which in turn In the end, you will most likely get hurt.
In any case, if it concerns or involves money, there will always be risks that may arise, such as in trading where all traders have the same opportunity in terms of profit opportunities but on the other hand they also have the same possibility of experiencing losses, and it is clear when you don't have any knowledge or insight at all because you don't want to first dedicate yourself to lots of lessons, so obviously in the end you will just waste your money. Moreover, you can get a lot of information from several sources about what steps beginner traders should take, you can get it on the internet and it's free as long as you want and my advice is don't put too much hope in profits if for example you don't have any knowledge at all.
