I think cloudminr is a great example of "how to scam people".
What was the plan in my point of view?

start a cloud-miner.
make people to invest with big discounts and profit calculations.
make them to reinvest instead of payout but make payouts to look like a serious service.
wait until you've got enough BTC and the BTC price is high.
pretend that your service AND - for sure - your twitter-account has been hacked and it takes time to restart a new service
use the time to sell the scammed BTC
still pretend that the "hackers" do that
disappear

i think this is what happend and will happen. i don't belive the official story.

Yeah this seems to be the business plan for all Cloud Mining services, thus far. Sucks to get scammed when it does happen tho.
