Sure thing. It is not impossible for bitcoin to reach 50k. But it requires much time and more demands. As a matter of fact, the demand is always growing, thus bitcoin always rises. There will be a time when I leave my job and stick to my friend "Bitcoin" because bitcoin is the future, bitcoin is the hero, bitcoin is life. Added to that, I believe that nothing is impossible. People should always be optimistic toward anything even if it has 1% of success.
Some people are making a lot of money thanks to bitcoin and they are able to leave their jobs, but the majority of people here in the forum are not so lucky so I think this is still not the right time to leave your job in order to pursue a career in bitcoin, the best thing we can do a t the moment is to do both, keep working and use your spare time to earn bitcoin as a side income.
