Honestly if its listed as safe on Badbitcoin i would run the other way.  They have a habit of picking some massive scams to claim are fine.

See GAW for example.

It was on their safe list and they still wont admit they got that wrong....

In fact their claims about GAW look very similar now to what they now have listed for MS.  It may even be word for word.

Miningsweden.se       1+2*+5+7           => 4/7 = Highly Suspicious (*Paused paying their active contracts and claimed of hosting a miner which is not even launched by the concerned vendor)

Thats from the link in my sig about how to avoid cloud mining scams.  They scored badly enough to make the Ponzis yet to collapse list and probably need moving now
