It's a risky move for anyone to take, and the options you have mentioned are not necessarily high earning. For a start, bounties is the only one you can get involved in for free, and that is assuming you have free internet access and plenty of time on your hands. Mining for any decent amount will cost a fair bit to set up, although once you've 'broken even', it can be quite lucrative, especially if the coins you're mining are on an upward trajectory. And thirdly, getting involved in trading (with no outside income) is a very risky game, and definitely not for beginners. You could lose all your money very quickly if you don't know what you're doing. My advice would be to stick to the day job, even if it is not earning a great deal of money, as at least you know you'll have your expenses covered. Then spend your spare time learning and slowly building a cryptocurrency portfolio. Good luck to anyone taking the plunge though.
