Vladimir - Are you and your associates willing to mine at above 51%? Do you plan on maximizing profit or would you take measures to ensure confidence in the integrity of the network?
I have no reason to believe that we will ever be able to reach anywhere close to 50%. Even if we reach such capability (which is highly unlikely) it would be very unwise move for more than one reason.
Just check old ArtForz's posts on the matter (right about the time when he killed CPU miners, FPGA miners - take notice). It was discussed at length back then.
1. It makes no sense to have more than 50% and keep rising hashing capacity while being honest. Your machines will be simply driving difficulty up and competing with each other. Easier and cheaper to shut some down.
2. It makes no sense to have more than 50% and be dishonest as well for a variety of reasons, including ethical, public relations, investor relations, legal, long term profit.
You people give not enough credit to Bitcoin's design. It is much deeper than many get it.
My goal it so build a Bitcoin mining company that will be sustainable long term and that will continue ongoing investment into new technologies and new mining capacity, get listed, get optionable. I just cannot wait a moment when I can sell naked puts and roll them perpetually (if allowed by law, damn insider trading thing).
It will be not so much a technological company but a financial one, more specifically an asset management company. There are plenty of examples in non-bitcoin world of companies that are being managed by a handful of professionals but have billions under management. Just check out biz models of companies like AYR and most REIT's and specifically O (my favourite, if I can I want to emulate their biz model, specifically stable monthly dividend and lack of leverage).
I respectfully suggest that many people here got it all wrong. This is not about killing Bitcoin and getting into 51% territory. Ask yourself why the hell would we want to become #1 target of guys with badges and guns? It is all about becoming the Bitcoin REIT and eventually being traded alongside of my darling O (Realty Income Corp. NYSE). My best estimate is that we will climb to 25-30% for a short period of time if we are lucky, just as I have done with GPU's at one point. History tends to repeat itself. I bet on it.
The FUD is being generated in this thread not by me, but perhaps by those who overextended themselves (we know who you are, lol) by buying FPGA's and now they are trying to pass their own fear to you. (do refer to my signature for legal disclaimer).
