I have bad experienced with a cloud mining "hashocean" I think. And also my friend, we've invested and like cloud vanished and not leaving any traces at all. After that I've started to doubt bitcoin and leave. Until now I came back to regain what I've wasted for so long. Scamming sites are made to gain profit to fool others that I condone and will not be on that situation again. My advice is just be careful and be observant on anything/sites other than this forum.
Ive never done cloud mining. I wanted to do it last year, but decided to quit after I made some research and discovered that there isnt any profit in it. Most of them are even scams. I heard it has become worst this time, that people are getting nothing at all.
I also read more bad feedback on this method of bitcoin earning, if you can buy mining rig and build own bitcoin mining this is much better and it is profitable all of us do not want to scam our investment that is why it is good to avoid this kind of investment based on what i read in this forum.
