zhoutong, I do appreciate what your are doing for the community. This is a hell of responsibility your are taking, good job.

But, please, explain me - how could you be keeping the whole bunch of Bitcoins in a single wallet running on the VPS (!!!) in the wild? Having $200,000-250,000 worth customers' funds would make me invest my own money in renting dedicated server at least. Or two. Considering even this not being totally secure - it still would provide much more security at $50/month cost.

But hell, who cares about security at $50/month! Being a hero at $200 grands is much more effective!
