When traders lack knowledge of trading, it will be difficult for such trader to achieve what other traders are achieving from the market, because he or she will not trade when it is time to trade because he or she lack the knowledge of cryptocurrency trading. Lack of patience can make traders to lose their funds in the cryptocurrency trading, because you need to apply long term holding even though the price is still decreasing in the market, because the price will not remain like that forever in the market and if you can endure for the bullish season to appear, it will make you not to lose in your trading. If you don't want to lose your funds in trading, try to eliminate fear in your trading which is the major thing that is causing some traders losses some time in the cryptocurrency trading.
If I read what you said above, you said you prefer the spot investment method (long term holding), Even though there are several investment methods, spot and trading both have risks. For me, spot is not that scary compared to trading. If someone is a beginner who wants to try investing, I think it would be best for them to look for a friend or close relative who has experience with crypto, at least that person's knowledge will understand much more quickly than if we learn it ourselves.
what do you mean, if we don't want to lose funds in trade, you have to get rid of fear? In my opinion, even if you eliminate this fear, it doesn't have a big influence on whether you lose your funds or not. In this case, it is the determination in choosing assets, if we choose the wrong asset, even though the fear has disappeared, we will still lose our funds.
