A coiled spring of buyers , waiting for an upside price breakout from  the "bottom" is demonstrated by volume figures in dollar value over the last week..

After two months of a trading range 0f $20-50million value a day, once it appears that people are convinced the 'bottom"s in at around $400 and it pushes to the upside above $450 then the lurkers buy quickly to establish positions looking for an upside of previous highs and above.

The sudden jump to $170 million over the last 2 days from $20million on May 17th ( 600%+++)  and from an average over the previous 2 months (400%).

Most will not be selling until previous highs are reached.

Looking forward to breaking 1160 sooner rather than later.
