BTC is a real warrior it will fall and rise again. We have seen such up and down with Bitcoin. Current market situation is not good, but never forget that in year may 2010 BTC value was $0.01 to all time high at the end of the year 2017.
Up and down is the part of cycle of any currency for it's healthy growth, it also happens with Fiat currency. Never forget that bear market condition is a correction time and BTC going through correction phase. Hold your Bitcoin and wait for right time, any price prediction at this stage is uncertain.
