Except that miners have zero incentive to destroy the bitcoin network. Its like cutting off your own head.
Not true miners obviously have incentive to destroy the bitcoin network. This doesn't mean they are doing it intentionally. What I have learned at this point is that if wall street wants to destroy bitcoin one of the ways is creating a slick, easy to use pool with great payouts and lots of incentives. Miners will jump to them for easy "profit" and once the network gets 50%+ it's game over. You think wall street would have a problem dumping billions of dollars they would never see again into destroying bitcoin? They would do it without thinking and the billions lost creating a slick miner friendly ticking time bomb would be like you losing a dime in the couch cushions.
[Tinfoilhat] And what a better way would there be to destroy Bitcoin, than by its own users? What a proof that decretilized and unregulated currencies can't work. [/Tinfoilhat]
Not that I believe that, but the irony if something malicious happens, that was only possible thanks to the endless greed of Bitcoiners (WOW, I make a Satoshi more a Week there!), would be priceless. Actually, there may even be a lessen to be learned here and better now Bitcoin gets a big hit from this than in a few years.
