It's normal don't worry almost a year we all suffering for the bitcoin price falling down their price value, nothing new for this because for me 2018 is bitcoin correction hoping early next year bitcoin will moves in good condition.
Indeed, that price fluctuations today wasn't that bad compared of what happened last middle months of 2017. The situations is not worst yet, we still have more challenging times to move forward with btc and if trading will always be our ways to do it, then continue and don't give up holding more coins. If we will see the price is recovering before next year until such time the last days of 2018 must perform surprising demands, so be it.
