I mean....I know that the difficulty going up means more ppl are mining, means better decentralization, etc. But FUCK! Mining profits keep getting smaller and smaller! 
It just mean the mining will be concentrated into cheap electricity places like China. It happened to the btc mining.
No, I doubt that's the main cause. POS is coming soon, at least, too soon to invest a giant mining operation into Eth. More likely, it's a combination of difficulty bomb (by design), and more rigs being brought online/switched to Eth mining.
Interesting.
From what I've read on other Threads - most of the difficulty rise comes from new mining hardware, improvements in GPU mining techniques and new people coming into crypto-mining because of ETH.
Someone could research and post figures on wallet-qt growth rate over the last 4 weeks!
The difficulty bomb will start to phase in in November. So I think the Ethereum developers has about 1-2 month to solve the problem.
Someone posted 5 months, now you've posted 1-2 months - this alleged difficulty bomb is more elusive than the Yeti!
Does anyone have a link too a formal or official announcement from the Ethereum Foundation - that this thing actually exists or are the posts like sightings of the Yeti?
i guess then this wont do either but i this guys are removing it from the ETC chain so its on the ETH chain too
Remove lines 305-309

if you dismiss the worries of this miners by saying the diff bomb is gosip do you have proof it isnt in the code ?
couse if they trust you they might get harmed ?
Don't ask me, PM the Ethereum Foundation!
They will send you email, with a reply too your question.
