Cloud mining will easily leave you without pants.
yeah There has been a prolioferation of cloud mining scams recently
Unless you know what you are doing, I would not get into it
they are not all scam, you can start to invest a small amount if you can't trust them, and increase that amount by little for every next investments
this is what i'm doing with some site that ask you to invest, not exactly cloud, but they work in the same way
At this point and due to the usual high price of electricity, low price of bitcoin/alts and mining difficulty, its quite difficult that you can actually ROI setting up the latest mining equipment yourself
If you dig onto what it takes to mine yourself at a big scale, even just as an example, you will understand what I mean
Now how is someone going to do that work for you and yield you profits if you would not be able to succeed planning it yourself
Its pure logic
Now you can mine now with the attitude of bitcoin going up in the future and compensating the loss, but then it depends on if you want to turn actual FIAT to BTC or change your electricity for BTC
At this point you do better buying or investing in other places like BTCJam or other kind of projects
Hope it helps
