cloudmining.website is generally believed to be a scam.
certainly not true for bit-x and hashnest, they are proven to be legit

many people here believe that if they do not profit they are scammed...
If they were talking to you it could be to do with signature of "(up to 152% bonus market regulated)". It makes it sound like a big profit... some might say that is misleading to put up to. That it would be more realistic to put your average return...
So not everyone is innocent. Things such as when you buy hash from most genuine cloud mining services do not use "up to" or other unrealistic words. Look at hashnest you will see what honest looks like.
