If there is one thing i've learn regarding ASIC manufacturers.. Is that they never spot on their target.
There is always a difference between the announcement and actually delivering said specs, whether with spondo, bitmain, BF, and AM..
When taking (pre)orders, you can generally bet against vendor claims for rather obvious reasons. Bitfury however is one of the few exceptions so far, delivering their asics pretty much on target (what was it, one day late?) and on spec (also in a different league than the competition, outclassing 28nm competitors with a 55nm design).
More importantly, note that BF is not pre selling anything atm that Im aware off. They got their money from VCs and only released this information long after securing the funding. They have very little incentive to lie or even exaggerate. If it where a bluff intended to scare competition, it would be too late to have a meaningful impact.
Puppet, would love to discuss further, your point of view around financial incentives has merit, but it's hard for me to take what you write seriously when it is mixed with emotions, anger or disrespect - it is simply distracting.
As for 51% of mining my point is that it cannot come from the BitFury DC, no one wants the bitcoin network to have a single point of failure, logical (pool) or physical (actual DC). Even if you do not believe in that argument, please assume for a second that it's true, then where would you think the rest of the mining power would come from?
