After beginners experience several failures of course they will realize the importance of having an understanding first before deciding to trade and also they must be able to be patient with every process we go through because if we cannot be patient it will certainly be difficult to persist in trading and with several failures then we will no longer learn it well so we can't make anything from trading and we will only get losses in trading and it would be better when we first try it, we can use a little capital while we are still in the learning stage and when we understand it well of course we can try it with larger capital to be able to get the profits we want.
Even though they already/finally realized it, it can't help that much anymore because they must have learned a lot already but they can use it and gave someone a tip before they start their journey here. With that being said, several failures can actually make you learn it well and you will eventually make money on trading. This is why like you said, patience is also important and as well as having a good amount of capital.
There are still demo trading that we can use first, if our capital is only limited. If we want to do trading, obviously we must try it but we may need to equip our selves with good knowledge first and then we need to start with demo trading first.
Failure experienced by a trader will of course provide experience and learning that they must remember so as not to repeat mistakes like that when they return to trading because without learning about the mistakes we have made, of course it will not be possible to make a profit in trading.
Trying trading on a demo account will certainly make it easier for us to learn about trading so that we will be able to understand trading well before trying it with the capital we have, but when using the funds we have of course this must be done carefully because it is very It's different when we trade with the funds we have.
