Completely unnecessary. GHash admins themselves have stated that they don't favor a 51% attack, and in case if such incident happen, it will harm them the most. BTW.... where did they moved their mining power? GHash charges no fees. Pools such as Discus Fish charges a fees of 3%.
I completely disagree. But you can continue insisting that it's a good thing to have a pool with 51% power over the blockchain.
At least SOMEONE is doing SOMETHING about this issue, besides selling out and bailing before the next Gox episode.
I wish more people would move their miners elsewhere.
