I first bought at $648. I kept buying at various prices, my average is way below that, so I can enjoy the ride relaxed..
I've learned so much, I'm almost too calm when the price swings drastically.. I must admit that I can afford to loose everything, would not be very happy about it, but life would go on..
Haven't sold a single bitcoin yet... I''m not planning to sell anytime soon.

Good luck to you all
