Hi Guys

i was interested in maybe cloud mining and looked for monthly or a quarterly contact to limit the initial investment and to see if it generates a positive return.  However, cloud mining seems incredibly expensive if I understand things correctly.

Cloudhashers will give me 1 day of 35Ghash speed for $12.  That is very expensive as I would earn about $12 after 1 month of mining at 180 Ghash/s.

Bitcoin hashing sells 4month of 1gh/s for 4Bitcoins.  So I would need to earn more than 1coin a month at 1gh/s to make this a profitable envedour.

What am I missing or why is cloud mining popular?  Seems rather expensive compared to buying a UBS stick that gives you 2 Gh/s and putting that on your computer
