I think my worst trading decision is when i sell my appcoins in such a low price. I sell it at $1.5 and after one day the value of appcoins became $4.2. I did not wait for the price to go up before i sell it.
In my case my worst trading decision I made is when I got panic when I saw the red lines on the exchange market. It makes me feel worried then all of a sudden I made a decision to sell my coin at a not so low price but I didn't satisfy on its exchange rate. I feel so messed up that time, and also I realize that I should learn the virtue of patience.
In my case, I don't feel any regrets with the decision I am making especially during those times that I do trading, whenever I felt that my action is not good, I am just taking it as a lesson, realizing what was the wrong move I made and take it to a consideration so that next time I know what my next move is. I don't feel any frustration so I won't be down, I am still positive with all the wrong mistakes I've done.
