This is a very strong resistance for Bitcoin , because it is also corresponds with the 200 Moving Average. In order for the uptrend to begin, price has to break and close above both, $61.8% Fib resistance and the 200 Moving Average on a daily time-frame.
Break above should confirm Bitcoin intention and could send the price up to the $8820 resistance, that is confirmed by two levels and corresponds to the uptrend trendline.
But, if the current resistance will hold, the consolidation could take place. BTC /USD could be trapped between $6170 and $6550 for some time. In this case break above the resistance or below the support would determine further Bitcoin direction.
