Bitcoin can't break 50% fibonacci levels on 25 March 2018, it means (just my opinion), bitcoin keep continue for the downtrend. Bitcoin must break resistance on 23.6% and 38.2% fibonacci levels to change the trend to uptrend. If bitcoin hit support line on 0% fibonacci, prepare for the worst price in USD 6604 - 6166 to bounce back (hopefully). Bitcoin still need more volume to change the trend.
