I'm in the same boat as julz. I invested just before cici at about +1600 site profit, I stuck it out through the swings, and am currently still -7 profit. I figure the site needs to get to about 2700 profit for me to break even on investment.
You just have to hope that a lot of BTC doesn't get invested before JD gets up 2700, or it'll take even longer to break even. Of course, if a lot of BTC gets divested then you'll break even sooner.
Edit: It appears that the amount invested has remained fairly stable for about a week now.
