Bitcoinica

This seems far more advanced than usual for Bitcoin. Nice! I have little insight into the security of your software, but I hope you have also considered the peculiarities of…

Very very cool! The idea is great and the interface looks slick! However, what do you do in terms of protecting people's accounts? You say that the money is stored in your…

Question for @zhoutong ... When did you start working on this project and have the negative events (guy losing 500K, MtGox hacking, etc) of the last few months affected your…

I'm the creator of Bitcoinica. I'm not so established here. To be honest, I'm only 17. You're 17 and you've already created something like this? I see a very bright future ahead…

That's a great site and will help people that haven't got any trading experience to 'play' a little bit without having to do all sorts of things in the 'real' money market A…

This is true, I expect him (or her?) to go far! Unfortunately, seeing his age put me off depositing money into the account I just created. When dealing with my money, I want a…

To be honest, your age isn't a problem, because the average above-average developer is still not competent to write this sort of software. If you had been doing security and…

A brand new financial trading platform written by a lone teenager in China? Here let me give you lots of my money! Not. :-) Somewhat tongue in cheek. I wish you luck and admire…

I already mentioned below that I thought your site was nicely done. But you didn't answer my questions directly which makes me a bit wary. My questions aren't site security…

Without meaning to put a damper on your technical work, you should keep in mind a few things: -- systems that work with money are attacked hard and often, by intelligent skilled…

Considering all the security issues with the Bitcoin ecosystem and the resulting mistrust, I think you need to be very explicit about your security.

I like the site. A few notes: - Running on Heroku is not really an asset security wise. I would put something more significant to ensure users that your site is secure. - Make…

Sadly, I have to agree with this. You're very smart, zhoutong, and your eager and polite acceptance of feedback does you great credit. But I would not attempt what you're doing,…

Spread seems high.

why don't you allow to withdraw bitcoins? Isn't bitcoin built because it's easy to make transactions? Why withdrawal can be done only through mtgox redeemable codes in US dollars?

It looks great. It's good to see more things appear in the Bitcoin space. I would add a tour page, perhaps with screenshots so people can see how it works without signing up.

Looks pretty cool. I dislike the random pink highlighting, it's noisy. Avoid smiles, as cool as it is, you must look professional in business ;) That said, maybe a security…

Hi, does it support PayPal?

That's a great site and will help people that haven't got any trading experience to 'play' a little bit without having to do all sorts of things in the 'real' money market A…

How do I logout without a logout button?

Sadly, I have to agree with this. You're very smart, zhoutong, and your eager and polite acceptance of feedback does you great credit. But I would not attempt what you're doing,…

Can you explain your margin fees somewhere on the site? Thanks!

I don't want to use mt.gox, I moved all my money out of them because the way they treated me and other customers, blocking my account and my money for a lot of time; that's why…

Yeah, I understand your concern. Bitcoinica has several features/characteristics that make itself like no other: - There's no Bitcoin wallet. Most incidents happen with stolen or…

I think only alternative is tradehill, and their interface/features suck.

i run intersango.com we have a solid platform that is rapidly advancing sign up and give it a try
