I'm always looking for a way to get Bitcoins for free for my own personal profit.  And at first glance this sounds like an interesting idea, with a small chance of success.  And I'd like to think it could work, but knowing there are people out there even more unethical than me, especially foreigners, and I don't feel confident about this idea as a result.

Besides, I'm sure they have tried to crack them and failed, so what are my chances then for actual success?  I think not good.
