Hmm as far as i can see there isn't anything wrong with this companie. And then they are partners with Genesis Mining, wich is a good sign in my eyes.
But depending on how much you wanna invest and if you are new to this, there are plenty of other platforms where you can try and test some cloud mining contracts. Some even for short term contracts.
If you want more info send me a PM and i'll try and give you some advice.
