Re: ***CEX.IO Bitcoin Exchange. BTC/USD, BTC/EUR. Official page***
Someone see if i am right on this maths 
3 th/s = 3000 gh/s * .11 cents (so sue me i rounded up i know its 10.5 cents per gh/s per month) = $330 a month in fees
At the time of this post btc is ~ $375 per btc and according to this web site: https://alloscomp.com/bitcoin/calculator
per Day 0.03743718 BTC $14.22
per Week 0.26206027 BTC $99.55 <.. (this is your payout. 3/4 of that is going to cex.io)
per Month 1.13949421 BTC $432.86 <... that's what a month is so subtract $330 - $432 = ~ $102
So buying 3 th/s on cex will net you only $102 and btw the price of btc/ghs at time of post is ~ .0015 btc = BTC4.5 meaning you would pay $1,687.50 to earn $102 a month
and Lord help you trying to reach ROI with that 102/1687 = 17 months.
So I'll let you decide is it a good time to buy cloud hashing on cex?

PS
I know i didn't even count the difficulty increase that will even eat up the $102 profit over the next 17 months.. ((too much of a hassle)) i think i made my point .

The difficulty increase will make people lose money within a few months.
here is my story.
Lost about 45% of my 7 bitcoins within a day period. They implemented futures trading or whatever it is called and within one day I lost a lot... I used them for GHS mining for a little while and everything was ok during that time. I am pretty sure their change easily wiped out 10,000 + bitcoins worth of peoples value across their entire website the day they added this change.
I am surprised no one has really commented that on here, but I realized I didn't say my story either. I am giving them a neutral rating because I really don't feel like getting red negative trust scored by them as retaliation. Seems like anyone with default trust these days abuses the system. Hopefully people don't use cloud mining as you just lose money.
