&gt;People seem to forget that it is NOT in BitFury&#x27;s best interest to perform a 51% attack because, bitcoin&#x27;s value will plummet if they do that.<p>If BitFury can turn $200 million into $400 million <i>now</i> rather than over a couple of years, why on earth would they care about the side-effect of killing off bitcoin?<p>For the avoidance of doubt, I think that BitFury&#x27;s best interest is <i>BitFury</i>; as long as they make a decent chunk of money, the end result for bitcoin is - and <i>should be</i> - immaterial to them.
