Badbitcoins.org deserves a slap themselves.
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
That says a lot about Badbitcoins.org:
Declaration of Interests. We currently have personal and project investments in Bitcoin VIP and Mining shares at Miningsweden.se (Now closing their mining), and Ethereum mining shares at Genesis Mining. We would not invest in anything we considered to be a Ponzi or Scam. As a project, we are not directly funded by any organisation and depend on ad revenue, our own, and other donations, and our external investments. We also provide links including referral links to trusted 3rd party sites, not including *External Advertiser - Check our Badlist*s beyond our control. Updated August 2015
PS - As a friendly tip, we probably aren't the people to generally ask about good bitcoin investments. We are pretty good at what we do, but so far, like yourselves no doubt, we aren't really that succesful when it comes to our own investments. Mintsy being our latest fail.
