this is called horse shit, they did double spend @ 23% and nothing is preventing them from doing so now, they shouldn't have more than 33% ( read the selfish miner) neither any other pool no mater how honest the operator is, you never put trust on any individual it must be distributed equally among everyone on the network.. the is what Bitcoin as concept came to solve...
you fucking noobs don't get it right ? you really piss me off !! "it is ok" , "it is not 51% yet" "they are honest" "who would destroy their business model" well I guess you think the same about your banks, it is now that we do something about it or it is too late....
The problem is that regular miners are attracted by 0% fees. You can do nothing unless you have enough
BTC to incentive the half of the ghash.io miners to switch to your pool which also has 0% fees and you have enough resources to maintain such a pool.
Edit: or, well, all their miners as ghash.io states that 55% is the external miners and 45% - internal ghash.io hashing resources.
