Fear of loss is not bad, but fear or risk is very bad, and that can make you stay at the same spot for a long period of time because who doesn’t take risk will always stay at the place he is yesterday. Risk is a paved way to riches, so why be afraid? One thing people who are afraid of trading lack is knowledge because there is stop loss, and no matter the amount you put in trading, you will still put stop loss, which even though you are not active, you will not lose. more than that, which definitely means that you can put your stop loss at the amount you can afford to lose.
So to me, there is nothing to be afraid of because in trading, you just need knowledge, and with that, you are covered, and failure is also part of knowledge and success, so even if you don’t use your money to trade or do anything pertaining to crypto, you will still invest in some physical investments, which even there you can still lose, so loss is everywhere.
That's totally gamble if you randomly put your stop loss without analyzing the market price action that's too risky it would likely always hit your stop loss instead of making a profit.
The only reason why people are getting scared it is because they are not confident about the position they made and lack of knowledge but why would you go into live trading without practice that's totally gamble you should start with paper money to build up your confidence and to test the strategy that you learn anywhere before going to live trading.
Sample make a challenge for your self that you can profit with your paper money once you are able to make a profit on paper money and you learn how the market works then go for live trading and make sure that the capital you are going to trade are small amount that you can afford to lose so that you can control your emotion before you go into live trading.
Making a profit in trading is not instant it needs patience and you should learn from mistakes you made while you are trading with paper money.
