My system is a ponzi, that's exactly what it is. A ponzi is a system that the host takes investments and guarantees a return. However, this ponzi will never stop, as there is no way for this to ever collapse (unless, of course, my cloud mining site stops paying out). If the the cloud mining site every stops paying out, I will immediately send all people their account balance so that their money is not trapped in the cloud mining account any longer. This makes it a safe investment to earn 5% each day.
