The issue seems to be sustainability, the last two hanging man formation have seen a reversal but we always encounter resistance and there just isn't the buying volume to break through and establish a new support level. 

I suspect this is partly to due with hangovers from Gox, Neo et al and partly (maybe) because those trading are working within more professional parameters ie profit-taking is realised at lower levels but more often.  Personally, I think the longer we go without some ludicrous bubble, the better; indeed it would be best if there was never another 'bubble'.
