There's no safety even if GHash.io is below 50%. How can we tell that GHash.io and BTCGuild aren't already colluding? They have 61% between them.

- legutierr 13y agoEven without that collusion, if you control 40% you still have a high probability of pulling off a double-spend attack. My recollection (sorry, I don't have a link, so I might be wrong) is that someone somehow associated with GHash.io already pulled something like this off when they were still below 30%
