as a crypto trader sometimes, there's this question that usually comes to my mind and that is if there are people out there who are into Bitcoin investment fulltime and then if crypto currency paid me more than my current job, would I quit my job to go into Bitcoin fully?

So yesterday, as I went out at night to grab some snacks for myself. I bumped into a group of friends who were also into cryptocurrency trading. Then it turned on me that I should drop my question of whether Bitcoin or crypto trading could be a full-time hustle that would continuously put food on our tables in the near future and if they could quit their current jobs going into Bitcoin investment fulltime?Their responses were quit alike saying that
 "to them, Bitcoin would continue to be a side hustle and since the price of cryptocurrency is volatile they could loss the value of their investment at anytime. they also said that they couldn't quit their jobs as that would continue to bring more capital for their investment"

after this encounter, I decided to bring this question too to the Bitcoin community itself so I would hear from other traders like myself. What is your opinion about this would you quit your job and go into Bitcoin investment, considering it as a full-time hustle?
