Bitcoinica is worthy of at least a few more. Freakin' amazing that a 17-yr old built it in a week and it's designed well, intuitive, and (thus far) has been very smooth and glitch free.
Seriously impressive.
Yes, that is just what I want for systems that hope to handle hundreds of thousands of dollars. Young coders with no financia services experience coding it in a week.
As a proof-of-coding ability. Sure, absolutely fantastic, someone offer this kid a job.
As a bitcoin exchange when we have had hack after hack after hack? errrr, not so much.
Soooo... maybe you should encourage people not to put more money than they can afford to risk/lose on something so new and unproven. It would be insane to put anything other than "gambling money" into Bitcoinica at this stage. But with that said, Bitcoinica is damn impressive and worth playing around with.
