From what I understand, 51%'ing a network does no harm unless the pool operator has bad intentions.
Are you really wiling to bet the value of of your (and mine and everyone else's) bitcoins to the intention of any single anonymous pool op ?
It doesn't make sense why they would. They are hurting their own cash cow too otherwise.
we should never put too much trust on one individual, Satoshi nakomoto designed the Bitcoin protocol so the trust is distributed among all miners and not one single pool/organization/individual, what is happening is a potential risk no matter how trustworthy the operator is....
otherwise I would not count on Ghash.IO because they are not trustworthy, what miners are not aware of is that this same pool tried to double spend few months ago when they had only 23% of the network hashpower and there is nothing stopping them from doing it again, especially now when they control this amount of power. for reference
https://bitcointalk.org/index.php?topic=327767.0please explain to me, why they have 0% fee ? what is the point ? now that they are being a big risk why didnt they do something about it ? the only effort they did is to release a statement that once they reach 51% that they will give the chance for people buying power there to point their miners to other pools but then it will be too late....
it seems that all effort we are doing doesn't count for anything, and it seems that miners doesn't give a flying fuck about the network security, and it seems that each time we talk about this risk is like we do them a free advertisement because their hash rate keep growing ever since.
you miners are the only ones that can change this, so please start acting responsibly.
