I just know Genesis Mining and HashNest and they aren't profitable. The better option between those four sites maybe it's HashNest because you can sell your GH/s anytime and get your money back (but it's still unprofitable).
None of the cloud miners are profitable anymore. I seriously doubt they ever were.
When it comes to the most legit one then Hashnest wins. But when it comes to profit nobody wins.
Having a middle man makes it unprofitable.
