You indeed know very little about cloud mining and that raises the question if you're the original owner of above account? As is, cloud mining ceased to be attractive to anyone as soon as they become experienced enough to see through their resemblance with any ponzi scheme out there. At best, those early payments are carrots before donkeys and unknown to many, it is sending back to you, tips of the much you already invested and only few are lucky enough to even recoup their investment before the party is over, because there usually are no mining hardware anywhere.
Haha, you have noticed something. Well, you have a great point. Cloud mining are just ponzi scheme, a waste of time and money. You don't have control on your investment and you aren't sure about the longevity of site you have joined.
It seems very difficult but I agree with your comment. I've also invested in bitcoin cloud-based websites, and what I've found is that after 3 months I have not yet recovered my capital, and more and more information about fraudulent websites. This makes me very confused. I advise newbies not to exploit bitcoin with the cloud.
