So cloud mining is not an investment, it's a lottery, if you pick the correct scammer at the correct time you may win, you will loose in all the other cases.
The problem is that your winnings come from money stolen from somebody else. You know this and you approve this. So it s no different then stealing money from that other person by yourself.
Did you consider that if you play lottery and win you are stealing money from others?
We must understand this is not an investment, and they are not real companies it's like a lottery (without the positive social impact of lottery, here the scammer get the big part and of course rules aren't transparent nor fair)
They evaluate the risk of being caught by law and assumes the risk to perform the scam
We should evaluate the risk related to put money on them considering that their main objective is to steal as much they can
Anyway in the process someones are lucky and earns.
With the "real" miners you will loose, slowly, but certain
