You keep making these claims. 51% attack doesn't allow you to spend coins which are not yours. So while in theory he could technically repay investors by stealing from them in a 51% attack you couldn't do it with 1 BTC. He would need 550K BTC today and that number is continually increasing by 4 BTC per minute.
Of course its theoretical, but he could spend the same coin 500K times and technically have "paid everyone back".
Anyway, this whole 51% thing is side tracking from the real topic. I just wanted to point out today is no different from 2 weeks ago, and if you believe pirate is for real, denoting his debt in dollars is possibly misleading.
