Bitcoin is volatile. That's just the way it is. In 2014, the best advice I received was buy, hold and ignore the price fluctuations until year 2020. I'm glad I followed that advice because I have several friends who bought at $1200 and sold at $600. They all regret that decision, just like you will regret it if you sell now.
You need to wait until 2020, but baby, it's going to be worth it.
