I missed to buy bitcoin when it dipped to $9K. Then I missed it again at $10k thinking it might go down to $9k again. And now, I am waiting for $10k but it seems that it will not go below $11k again. I must be the biggest idiot in crypto world

It is possible that bitcoin will dip again. If your gut tells you to buy bitcoins, then trust it next time. You could have made a lot of profits in the last 2 weeks.
