I wouldn't want to quit my day job to go full time on bitcoin on the off chance that bitcoin becomes worthless(it's not gonna happen anytime soon, I can tell you that.) If bitcoin price were to skyrocket though, I'd probably sell some of my bitcoins into fiat.
You will not be rich, only those people who have balls to quit their job for bitcoin are getting the best rewards, sometimes we need to learn how to risk as that can only be the way to achieve our dreams.
