I think you can, but barely. It would definitely make your living conditions worse, and would be much easier for you to earn more from a job.
You can earn with trading, but it is quite difficult. I mean you need to read a lot and have a great practice. And always there is a chance that you lose.
You can just try and decide if trading is yours or not.
Well, I agree that you can easily make money in trading but its quite difficult and if you do not have any knowledge about trading you can't make money and income. In addition to that, I think you can't earn money without job and we all know that bitcoin is an alternative way to earn income but if you are expert on bitcoin it can serve as your job.
