No body can ever become rich with bitcoins..
Yes i have seen many become poor with gambling...
I think, you may be wrong or by mistake wrote wrongly. One can become rich with bitcoin investments over the time but difficult to become a rich from gambling. Whoever brought bitcoins around 100+ within a year their investments increased around 5 to 6 times. So invest wisely and grow your money.
I really think he mis-spelled it, it's true that no one get rich in gambling as people who get big profits there is already rich because they can start with big bankroll already.
