$BTC #止损策略 Respect the empty first

Stop loss means setting a loss limit in advance, for example, if you buy and it drops to a price you can accept, sell immediately at the stop-loss price. Just like having to brake when encountering a red light while driving, to prevent minor injuries from turning into accidents. Use discipline to control human nature, avoiding the mentality of luck that turns short positions into long-term losses. Each mistake should have a controllable cost, in order to preserve the principal and wait for the next opportunity.
