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.
Yes in the last few years there have been lots of websites claiming to be engaged in bitcoin mining but most of them if not all turned out to be scam so in fact there claims were just false ones and they were never into mining they were just trying to cheat on people with the latter's hard earned money.
