I am right now watching the ending few hours of another interesting ICO (Moonstone).

The invested amount has literally triplicated in last several hours of ICO, and may increase more yet!
Except the usual habit of investing at the last moment, the declining BTC price is also playing its role.

So guys, be 100% sure PureVidz ICO will meet the target. And could actually collect much more than the requirement. I would expect 100-200+ BTC, or near 100 as a bare possible minimum.
