People cheat - or try to cheat - because they think it's a convenient shortcut to get rich. But it's usually a mistake.
I agree, they are not getting rich by scamming. If they do that, think and afraid in karma. This is a bad habit so please who do this, stop it. It cannot give a better life.
Indeed earning from scamming cannot give them a satisfied life, as they will all the time will be worry about getting to the users and it will be dangerous as well, market says it is not good to keep scammed bitcoin as if you will earn your bitcoin then it will be much better than scamming, bitcoin is very good way of earning but if they use it incorrectly then it cannot give them profit, it is very hard to earn bitcoin as it is very expensive so please dont so this.
