You didn't answer the vast majority of my questions, even though they were pretty straightforward. If you want people to deposit money into your account, then they should have faith that you actually exist and that you will hold up your end of the transaction. This, in financial parlance, is known as counter-party risk. Will the counter-party to my transaction actually be able to guarantee their side of the deal? Who are you? So far, you are a 17 year old Singaporean, who registered a business in Delaware, when you were 16? How is that possible? Right now, to me there is a severe degree of counter party risk. If you stole everyone's money (not saying you will), and then I complained to the FBI, they would look at me and say "Are you stupid? You deposited money into someone's bank account 10,000 miles away, and you actually expected the money back?" "A few dozen people have deposited thousands and thousands of dollars." And yet you have enough money to offer 5:1 margin? If there are 50 people, if all accounts are of roughly equal size, then it takes just 10 people to max out their margin and the entire Bitcoinica has run out of money!!! But assuming a normal distribution of account sizes, and assuming that the ones who deposited the most are the most aggressive, then you would need much less than 10 to max out before you ran out of money. There are better ways to set up this company so that you can protect yourself and your customers. Even more surprisingly, you offer no protections to YOURSELF. This is a huge red flag. Why would you not be afraid of suffering consequences if bitcoinica melts down or if there is a huge fraud? From what I gather, you are asking people to deposit money directly into your account (another huge red flag). You are supposed to be held accountable, if there is fraud or if there is a catastrophic loss to bitcoinica, but you're not protecting yourself, at all. The only way is by remaining highly anonymous, and by living in a foreign country that could be outside the reaches of US law. If you cared about protecting your customers, you would set up a system of segregated accounts, so that one customer can't destroy people's accounts. I think bitcoinica is a fantastic piece of coding, it's slick and seems to work nicely. But in order to protect yourself, I would return everyone's money and just allow simulated trading. Even as a simulated trading account, bitcoinica is still a fantastic accomplishment. Then, once you have created a way to protect yourself and protect customers financially, by using things like segregated accounts, and by going through proper channels, etc, then it might be okay to start accepting real money.
