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.
