We should go for both job and bitcoin. A stable job is a full requirement in life while BTC just to make sure it adds up something on your life, something to spice up your life. BTC because a great knowledge in the advance digital money could be an advatage for future transaction.
Well it really depends if you still need Bitcoin as a way for extra earnings, because if you are earning thousands of dollars per month than doing Bitcoin as a side job is not efficient not unless your trading capital is big. If you have a big role in a company then you might want to focus on that instead. I as student can both balance study and earning Bitcoin as I still have a lot of free time compared to other people.
I will agree with you. Indeed it is a sincere piece of advice. He should take such bold decision according to his financial condition.
If he is making real big profit with bitcoins and thinks that he has sufficient knowledge and experience about crypto trading, he should quit job then. Make sure that he is having enough bitcoins in wallet to convert into fiat for meeting his daily needs.
If ever I master trading, i will really quit my job, sometimes we can get more earnings in trading than in our real job, well it still depend on the market trends but eventually when we have time for it we can get that tume as a opportunity to watch and earn in trading, plus joining campaigns and investing in ICo too. When I think my earning can be sable enough I will really quit my job.
