Just because you missed an opportunity to buy bitcoin doesn't mean your an idiot. Don't feel bad about yourself because that'll only make you feel much worse. I myself made some dumb decisions in the past with my bitcoins and now I have moved on from it. Buying bitcoin with the current price is still okay considering how big the change was since last december.
I think we're heading to my target entry point, $10K again..
Price still at $11k give it a couple of days or a week.
