Are you new to Bitcoin? We're in the middle of parabolic rally, or one of Bitcoin's periodic "bubbles." I remember once during the late 2013 rally, the price dropped 60% (from $900 to $360) in a single day. The price then recovered and made new all-time highs.

That's the nature of this kind of growth: extreme volatility. If you are new to these markets, it will definitely feel exhilarating and scary. Be very careful with leverage. You should also be wary of panic selling. It's a good way to lose your coins!
