1.  I have the same question.  I found a list of ponzies in here and almost effed up.  But where is a list of legit sites to cloud btc mine other than buying a physical rig, or renting hashes at a website like genesis-mining.com?
2.  Isn't there anyone in here that makes money with actual mining instead of trading and/or signature campaigns?
3.  How much giga hash power would I have to rent to make 1 btc and how long would it take?
