You may earn good money in compare to your job at a moment, and that may attract you to get full time in job but the risk is if bitcoin disappears suddenly in future and if you have not saved enough money then you will be left with nothing.
if everyone can get a lot of money from bitcoin I think everyone will go full time for bitcoin. because it works with bitcoin is not tiring, very comfortable and relaxed. no need to worry when bitcoin will disappear in the future. because you've got a lot of advantages of bitcoin and bitcoin I think it will last for 20-30 years or more and it was a good time to continue to get a profit from bitcoin.
Yeah bitcoin will not disappear overnight, its here to survive for a long time but it will be great if we can manage to earn from both of the which can surely make us rich in future.
