It (pbmining) is no longer competitive, a few months ago the price was almost half that cex are now almost equal, besides that you can not trade, not instant payments, time indefinite, etc

I'll rerun the 1 TH/s example with cex.io.

pbmining.com - Cost is 2.9BTC with no other fees, 5 year contract, and 10% referral program

cex.io - Cost is 3.17314BTC + 0.18USD per GH/s per month, and it is possible to liquidate your GH/s at any time
0.18USD * 1000 * 12 = 2,160USD or ~3.7BTC at today's exchange rate for one year of fees.
So cex.io is 3.17314BTC + ~3.7BTC or ~6.87BTC expenditure during the first year of mining.
You can subtract 1-2BTC from the expenditure when selling your GH/s after a year.

Still not a good deal compared to pbmining.

Yup, you pay about 30-40% of what you mine in fees...
And I know it's not a lot, but you also have to pay fees for trading AND transaction fees for every withdrawal...
So in my opinion, PBMining is awesome. Would've been even better if the price would be at 0.002 BTC / GHs now, WAY faster ROI and I would invest a LOT more if it was Tongue
