How to know if a cloud mining is profitable?
It is always profitable for the cloud and almost never for the miner. Genius business model; dunno why people keep throwing their money at it but I guess they repeatedly count on people not understanding diff and mining - and it seems to work every time.
Well I can almost totally agree to this one as my income on Cloud comes from intensive trading almost all day long for the maximum profit. For only mining purpose I would not recommend at all.
