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.
