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 
If your attitude is always like this then you will missing the right time again and again. It isnt be practical to just always wait, we have to make a choice and risk is part of it. So take what is comfortable to you and regret everytime you take a blind eye of an opportunity for a lifetime or take the hardest way, maybe wrong but if the wind blows towards you, jackpot prizes is on hand.
