With this kind of HYPE/ponzi kind of game it's only a question of time before losing money. If a ROI is fold above any competitor, it is very likely that you are looking at a scam. Some people still manage to get some bucks, but you have to be among the first registered.
For most investment schemes within the cryptosphere you have to be within the first dozen people to register in order to walk away with even what you started with, let alone leaving with more money than you started with. This is especially true when it comes to these cloud mining sites.
Cloud mining loses its value with every halving, and the contract value can basically be divided in half as every halving rolls around. The hashing power has constantly diminishing returns, and in some cases, like with hashocean and topmine, you lose it all.
