“GHash.IO does not have any intentions to execute a 51% attack… it could risk our investments in physical hardware and we see no benefit from having 51% stake in mining”.

Concerns however have been raised in response to suggestions that Ghash can be trusted even in the theoretical scenario that it gains 51% hashrate of the entire network. It is argued that although Ghash itself might not profit from such an attack, they might be coerced or bribed  by government entities or entities which may see bitcoins as a competitor. The currently increasing hashrate share of Ghash therefore is seen as alarming by some, while others consider it to be a temporary blip due to numerous unpredictable factors.
