Cloud mining

[Garcicasti]

First, i would like to say hello to the entire comunity, as i've just registered myself.

Well, i've been wondering on investing in cloud mining, as i definitely don't consider buying an ASIC or similar an option. So i've been searching and the best webpage i've fund as for me is cex.io. But now i've realised how much do they earn as "electricity costs": 0.18$/GHS/month!!
So i would like to ensure myself, because i'm not sure if i'm doing the calculation right, or i am doing something wrong.
I have enought money to invest for 200ghs on cex.io, then if i take the bitcoinwisdom.com calculator it says that they can generate 0.1 BTC per month, which is like 42 dolars right now. But, if i understand right i have to discount that 36 dollars JUST in electricity costs. Is that right???

If the answer is yes, i would like to now if the scrypt.cc calculator is more or less real, i mean, if they take another "hide comission".

Thank you so much,
Andrés.

No Cloud mining is profitable at all, and CEX.io is more trade site than cloud mining or hashing.  That's the only way to keep up on CEX is to continuously buy and sell hash by monitoring the price difference, which you're just better off trading at an exchange if you're going to trade.

None of the others cloud mining sites will allow you to even break even.  Not PB, not Genesis, not GAWminers, not Scrypt.cc.  Even if you're going to lose money cloud mining, at least pick a decent priced one like the following:

I hear they even give out free hash sometimes, but just don't count on making a ton of profit or ROI.

Yes, cloud mining can be profitable. Check out the thread below:

Yes it can, you just need to do some research and choose the right service!

No Cloud mining is profitable at all...

how about some calculations or other arguments?

No Cloud mining is profitable at all...

how about some calculations or other arguments?

Example 1: hashnest.com
Price per GH/s: 0.00135BTC
Maintenance fee: $0.0032536/GHS/Day
Current BTC->USD exchange rate: $400

Purchase 1TH/s for 1.35BTC.  As of right now, that expects to earn you 0.01686BTC per day.  At current exchange rates, that's $6.74 per day.  Subtract out maintenance fees of $3.25 per day.  Net earnings per day is $3.49.

Now let's extrapolate over time using 20%, 10%, 5% difficulty jumps:
20%: -1.192BTC.  Cost of fees outstrips earnings after 53 days.
10%: -1.004BTC.  Cost of fees outstrips earnings after 109 days.
5%: -0.6203BTC.  Cost of fees outstrips earnings after 208 days.

Even with 5% difficulty increases you have no prayer at current exchange rates. 

Let's do the same calculations assuming BTC miraculously recovers and hits $750 today:
20%: -0.3115BTC.  Cost of fees outstrips earnings after 104 days.
10%: 0.1492BTC.  Cost of fees outstrips earnings after 203 days.
5%: 1.071BTC.  Cost of fees outstrips earnings after 385 days.

If by some miracle BTC skyrockets today and holds at $750, you still need to bank on having 10% or less difficulty increases to actually turn a profit.

That a good enough set of calculations for you?
