It was my mistake this time that I didn't have some cash in hand, I was take entry at high price with all of them. That is why when the whole market get crashed I regretted that if I had some Usdt I could buy. But the lesson is that, I will keep some cash in hand from next time. And I have to change my thinking that the market will always be the same. Though I'm just starting to get used to it. I hope I can learn from you guys gradually.
