I was wondering about that. I had two thoughts, neither of which I'm confident is very significant: - Finding and downloading the file is more work than just monitoring a set of bitcoin wallets. If the file gets leaked multiple times, and some of them end up in more obscure places, it might be much harder to find them. - The regular watermark can perhaps be defeated by tech-savvy pirates, but the bitcoin watermark would need the leaker to be tech-savvy. I think leakers are selected by the content owner, and not in general for their tech-savviness, so this might be pretty safe.
