Come, come, come, let me give you a short-selling suggestion.
Currently, the trend is downward, so if you're going long, you generally set the stop loss at the bottom of the previous candle. After a sharp decline, the main player usually collaborates with news to make an unexpected rebound to harvest the shorts.
So let me give you a logic for shorting. The target is BTC, the previous high of 112,000, which is also the recent support. If it breaks below that, it will turn from support to resistance. However, from a previous piece of news, BTC surged by 7,000 points, so my personal suggestion is to short at the second resistance level, placing an order around the BTC lifeline resistance of 115,200-116,000, with a stop loss nearby 117,000. This way, you generally won't get trapped, and you can profit, it's all big profits. The altcoins are the same, always choose to place short orders at the second resistance.
However, if you are going long, make sure to set the stop loss near the closest short-term support. Understood? $BTC
