The best thing about Bitcoin is that it's decentralized which means no one in particular can control the money that is flowing through the system. I guess that is why some people think that it's easier for them to get rich through it. Earning bitcoin is also the same as earning from any other types of currency. you have to work hard and think of strategies on how to earn more of it. The difference is that Bitcoin's value is higher when you convert it. Thus, after working hard to save a big stash of BTC, you'll have a big reward as well.
