A few warning signs from the past:
I am almost sure that bitcoinica.com is out of funds and they are keeping the site open to get more deposits and ponzi those deposits on those who want to withdrawal. The 17 year old just lost 250,000 Dollars and I doubt he has an extra 250K to cover his loss.
I would encourage everyone to withdrawal your funds from bitcoinica and watch the shit hit the fan.
We will lower our withdrawal fee in the next couple of days, in the meantime 9% is fair.
