If you never set stop loss points in your trades, I assume you won't make any money in the cryptocurrency market? Analysis principle: You belong to a risk averse personality and are unwilling to accept losses. If it rises sharply in a bull market, you are afraid to buy it, such as ETH now. You are worried that buying it will cause a drop and result in a loss of capital, so you will short out the entire bull market. If in a bear market crash, you immediately drop when you buy, and your subconscious is unwilling to cut losses, then you will lose all your capital in the entire bear market.
