Cloudmining is a scam. At the very least they take a percentage for doing all the work for you. The cloud or pool takes averages of everything and takes the lucky winnings off the top, or doesn't pay if no blocks are found, either way they win.
Here is a review that comes up for eobot, and it brings up some good points. They promise the same hashrate and return on investment for every coin they mine. If you don't understand why that is bad, you shouldn't be mining.
If you really want to mine, just rent a DigitalOcean or Amazon server and try it yourself, at least that way you can learn something.
