①About stop loss: The default stop loss for Bitcoin is 1%-1.2% of the current coin price [e.g., assuming 90,000 for the range of 80,000]. The default stop loss for Ethereum is 1.2%-1.5% of the current coin price [e.g., assuming 3100 for the range of 3000]. ②About profit: Usually calculated with 100x leverage, if profit >= 100%, reduce position or Rug Pull on your own. For a structured reduction of position, push for protection, with a default reduction >= 50%. Taking profit is standard practice. ③About dynamics: I write every dynamic carefully, the positions given in advance, support and resistance are calculated seriously, but it is not guaranteed to be correct every time. Carrying stop loss is our only method to prevent capital loss from worsening during trading. If you're afraid of loss, first take a stop loss on 1/2 or 1/3 of the Position and then observe. If it still doesn't work, decisively stop loss. Holding positions will definitely affect subsequent operations.
