That is all nice, but how many of your referrals are earning 4000$ every 20 days?
How many of them are earning anything and how many of them will lose money because they will never reach ROI?
It is amazing for you, but i am sure it is not amazing for them.
Cloud mining is not a way to make money. Cloud mining will not be able to provide us with a good income, a lot of things to watch out for because cloud mining is a very risky thing. Many circulated the news that almost all cloud mining only plays numbers only, they do not have any hardware mining. so they will run away when it has to get the money that has been determined.
