I don't trade Bitcoin, but if I did I would pay attention to the 6,600 level.  That's where it found support in April and February.  It has also been the low over the past few days.  It is a little oversold so we could see a little bounce here.  My guess is that the 6,600 level breaks over the new few weeks because since the all-time high was made in December, there have been three 'lower highs' made.  This means that the forces of supply are overpowering the forces of demand.
