If your aim is to get rich with bitcoins I think you are a little late I think you have a way better chance with altcoins instead since the prices can go sky high very rapidly unlike bitcoin, if you are a good trader bitcoin can give you good earnings but not as much as before.
Trading is the best way to make a big earning through bitcoin, but it has got the highest risk of losing. So the dreamy guys who wanna be rich through gambling should make some initial arrangement for investment. Based on the investment one will be benefitted, without investment being rich needs luck.
Anyway you need luck, but if the question is not how to win one time but how to make money then you're right
