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?
I started as a trader then I switched to become a long term hodler. Before I engage myself in crypto, I already have a stable job and a running business that up to now still existing. But I still don't quit my job despite of having other source of income, why? Because this is where I can earn a passive and stable income aside from being a crypto investor.
So my answer to your question is no, I will not quit my job and won't consider being a crypto investor/trader as a full time hustle. I agree with your friends, their job can give them additional capital for their investment hence it's wise to keep your stable job while treat crypto as a side hustle. This way, incase something didn't go as planned with your investment, you still have other source to be able to earn a decent income.
