> In other words, economics of mining leave among miners only the biggest believers in bitcoin driving out lesser believers. That's why in practice all miners are "honest" - all of them have dug the deepest hole possible, none is interested in short-term "profit" from double spending that would not return even a fraction of their investment. GHash already conducted a 49% attack against a gambling site. https://bitcointalk.org/index.php?topic=327767.0 https://bitcointalk.org/index.php?topic=327767.0 They blamed a rogue employee - but then the claim is no longer "miners would never do that, it wouldn't be in their self-interest" but "no single person at any mining concern would do that, it wouldn't be in the mining concern's self-interest even if it it was in their own". Which of course isn't true. (It isn't true in the wider financial system either, which is why regulations exist.)
