In all the time I am in Bitcoin I managed to make some decent profits but not enough to get rich. Actually, by far not. But right now that's not really my purpose. I am perfectly fine with making decent profits every year as I like to see my wealth grow constantly.
People can see bitcoin as a faster way to earn and to become rich. For me it is possible for bitcoin because we can also see its faster development through the years and its transaction and value is well developed so it is much tangible for people who are willing to work hard to earn. And compare to fiat in bitcoin there is much more high probability to earn more or in other words to be successful in businesses because bitcoin is an investment itself. You could also try on doing signature campaign where you can earn by posting to have an capital for trading in investment.
