As far as I know those people or individuals who got scam or became a victim are those don't have any idea what He/she doing or what the person entering at. It is some kind of stupidity if We allow the scammers to fool us. But having your own mining rig is good, however joining in any of the cloud mining site was just some kind a ridiculous things and most of the time they are scam mining site.
