Surviving technical challenges doesn't mean you didn't suffer them. Apple is an example that supports my point, not an argument against it. I didn't say Gox wouldn't survive the challenge. So you basically have no point.

There's also a difference between pivoting a company and starting projects from scratch and repurposing the project, which I think gnaritas believes happened here.

As any rational programmer would have done. The odds that this guy coded the Gox trading engine from scratch rather than reusing his existing code for trading cards is slim to none; that's just not how programmers behave.
