Didn't think the thread would be still alive...
Might as well make a final analysis and result, as my furthest predicion time ran in at end of May.
Put in another way :
Think you'll be able to sell for 0.038BTC/GHs at end of Jan 2014 ? That is actually possible, if you're lucky.
Think you'll be able to sell for 0.034BTC/GHs at end of Feb 2014 ? That is hardly possible, even if you're lucky.
Think you'll be able to sell for 0.031BTC/GHs at end of Mar 2014 ? That is near impossible.
Think you'll be able to sell for 0.030BTC/GHs at end of Apr 2014 ? haha, good one...
Think you'll be able to sell for 0.029BTC/GHs at end of May 2014 ? *omg* have you seen a doctor lately?...
I see a closing price of 0.007BTC/GHs.The cumulating losses simply ended up being severe and absolutely devastating in the 6 months period observed.
Estimated total net loss after these 6 months is exceeding 80% (!)
Together with maybe some completely crashed stocks or toxic derivates, cex.io cloud mining would certainly be among the biggest money-losing assets in the entire investment market worldwide.
...and the calculations were based on the original maintenance fee of ~3% - as of today it is so ridiculously high they don't even display the plain figure anymore
and leave it to the customer to research and do the entire math behind it.
I just hope the original poster that asked for my prognosis got out of this money-losing scheme as early as possible - which is the only thing you can do if you intendeded to do cloud mining @ cex.io.
Recognize the scheme behind it, realize the error and quit ASAP, this preserves whatever of your invested money is left.*
Original scenario :
Rent GHs at cex.io in early Jan 2014 and fully re-invest everything mined (merged mined NMC/IXC/DVC is approximated by assuming an additional 2% mining output, as I lack/forgot the exact figure).
Personal prediction :
Progressive and cumulating losses over increasing timeframes, listed prices are minimum resale GHs prices to avoid a net loss (negative ROI) for each given month of prolonged investment duration.
Overall, pending another massive Bull-run upwards in price, it really looks like the days for mining are simply over. Unless you somehow get nearly free power supplied AND manage to strike an excellent deal on latest-gen highend hardware... there's almost no way anymore you could walk away with a profit. You either have to get in BIG and take all the risks or leave it be.
Buying BTC (or altcoins of your choice) at a price you deem attractive is now almost the only way to play the game. Otherwise, you'd be highly prone to simply toss money right out of the window.
