I don't understand how this is news to people. Bitcoin was designed to be a secure, distributed, anonymous country. What do you expect to happen when you stop relying on Bitcoin to store your money and start relying on some random Polish webapp?
With that said, I think you could pick a better site to be the shining beacon of Poland's world class talent than the site that just lost a bunch of people's money because the only place they were keeping it was on a single EC2 instance store. If this is the top, I'm not sure I wanna see the rest of the class.
People should get rid of that "poland is europe's mexico" notion. It's the EU - you have the same legal security as in the UK, France or Germany.
