What are you afraid of with long-term holding?

Please operate according to your actual situation, don't follow me blindly. The pre-market trading price of 0.9U is my bottom line. Don't panic if you sell. It doesn't matter, there will be opportunities later. 3U to 5U is the long-term, if it keeps falling, you should protect your capital first. As long as you have the green mountains, you will not be afraid of running out of firewood.
