Does the fact that Ixcoins' difficulty has dropped in half over the past 6 months concern you?
In half relative to what? Relative to namecoin it hasn't.
Relative to Bitcoin I expect it should even though iXcoin's difficulty should continue going up.
Given iXcoin belong to some anonymous group and iXcoin offers no payouts I expect that only that group will mine it [for now].
Considering the fact that asic mining has blown up and many deep pocket investors are mining I would expect that those people will not give up efficiencies to mine iXcoin when there is no payout.
So that means it is CEX.io mining iXcoin against the rest of the world.
Therefore, relative to Bitcoin, iXcoin's difficulty should be going down but on a real basis, it should be increasing.
If/when ixc gets pushed mainstream and we start seeing fees, then I would expect ixc to be mined by everyone.
Until then I'm not worried about a 51 attack even if the rest of the world grows much faster.
CEX.io has taken care of any remote possibility of a 51 attack.
It has dropped in half in relation to itself.
