The whole situation surrounding cloud mining is really bad and it's not really something that I'd recommend getting into if you're looking for actual profits. I posted a very long essay about the subject
here a while ago but the general gist of it is that the more legitimate ones are unlikely to make a profit because the calculations just don't support it and those that advertise high profits are likely to be scams.
In fact, you might even have a greater chance of making a profit if you stick with less reputable sites because there is no way you are going to make a profit from CEX.IO or any of the other legitimate cloud mining sites out there. At least with a ponzi scheme, you'll earn a bit of money if you happen to be one of the first to "invest".
That being said, while it's impossible to know for certain which cloud mining companies will operate for a long time as opposed to running away with your funds, there is a useful comparison of cloud mining sites
here. You will see that both Bit-X and Hashnest score very well (4th place and 1st place respectively) which means that it's unlikely that either will be running away with your funds anytime soon.
On the other hand, you should also take note that just because a particular site has a good reputation doesn't mean that it will continue hashing away forever. CEX.IO temporarily closed down their mining operations earlier this year when the price of BTC went too low. AMHash was considered to be one of the more legitimate companies and look where they are today.
thanks such long for post.
